Description

Sclerotium rolfsii endogenous sclerotium rolfsii hydrolase and application thereof

Technical Field

The invention relates to an endogenous sclerotium rolfsii glue hydrolase of sclerotium rolfsii and application thereof, belonging to the technical field of enzyme engineering.

Background

Sclerotium rolfsii gum (also known as Scleroglucan, Scleroglucan) is a non-ionic water-soluble microbial exopolysaccharide formed by alternately connecting beta-D-1, 3 glucopyranose and beta-D-1, 6 glucopyranose residues, and a main chain unit connected with 3 beta-1, 3 glycosidic bonds is connected with a side chain of 1 beta-1, 6 glycosidic bond on average. The repeated unit structure makes the branching degree of sclerotium rolfsii gum reach about 0.33. In addition to having the bioactivity characteristics common to most beta-1, 3 glucans, the high branching frequency makes it highly water soluble. Due to the unique chemical structure and high molecular weight characteristic, the sclerotium rolfsii gum has good water solubility, pseudoplasticity, moisture retention, salt resistance and viscosity stability, and is widely applied to the industries of food, biomedicine, petrochemical industry, cosmetics and the like.

Currently, sclerotium rolfsii gum is mainly produced in a microbial fermentation mode. Sclerotinia sclerotiorum rolfsii is the most important production strain, and can be produced by fermentation by using glucose, sucrose, fructose, xylose, molasses and the like. Research aiming at the production of sclerotium rolfsii gum mainly focuses on the aspects of improving the yield and the productivity of sclerotium rolfsii gum and the like. Sclerotium rolfsii gum produced by the sclerotium fungi fermentation method has higher molecular weight, so that the solubility, the fluidity and the dispersibility of the sclerotium rolfsii gum are poorer, and the difficulty is brought to the industrial application of the sclerotium rolfsii gum. The activity of sclerotium rolfsii gum is closely related to viscosity and molecular weight, when the molecular weight is too large, the water solubility is poor, and when the molecular weight is too low, the physiological activity of sclerotium rolfsii gum can be lost. How to select a proper degradation method to modify sclerotium rolfsii glue to obtain an ideal molecular weight and improve the water solubility of the sclerotium rolfsii glue on the basis of keeping the activity, so that the industrial application of the sclerotium rolfsii glue is expanded.

It has been shown that the beta-1, 3 glucanase genes BGLM, PGLA, EXG1 and BGLF from Bacillus circulans, Paenibacillus, Saccharomyces cerevisiae and Alkaliphilic nocardiopsis are expressed in colibacillus and Pichia pastoris through recombination, and there is almost no hydrolysis to sclerotium rolfsii after treatment with 4 enzyme crude enzyme solutions. In addition, the sclerotium rolfsii gum can form a rigid triple helix structure after being dissolved in water, glucose groups on side chains are uniformly distributed on the outer side of the helix structure, and helix aggregation is prevented through the action of electrostatic force, so that the polysaccharide structure can be stabilized, and the gelling capacity of the sclerotium rolfsii gum can be reduced. The triple helix structure is very stable to heat and the sclerotium rolfsii gum can be dissolved to form a random coil single-chain structure only when dispersed in dimethyl sulfoxide (DMSO) or at a pH value of more than 12.5. The three-dimensional structure of the sclerotium rolfsii gum enables a glucoside connecting bond to be wrapped, the combination and hydrolysis efficiency of glucan hydrolase is greatly influenced, and early researches find that the conventional beta-glucanase can not play a role in hydrolyzing the sclerotium rolfsii gum so as to improve the molecular weight of the sclerotium rolfsii gum. Therefore, the screening of the hydrolase with the sclerotium rolfsii gum degradation capability has important significance for preparing the sclerotium rolfsii gum with low molecular weight.

Scraping 1cm²Inoculating the hypha into a 250mL shake flask filled with 50mL sclerotinia sclerotiorum seed culture medium, and culturing for 72h under the conditions of 28 ℃ and 220r/min to obtain a first-stage seed solution. Transferring the primary seed solution with the inoculation amount of 5% into a 500mL shake flask filled with 100mL seed culture medium, and culturing at 30 ℃ and 220r/min for 72h to obtain a secondary seed solution. Inoculating the secondary seed liquid into a fermentation medium in an inoculation amount of 5% for fermentation.

Inoculating the strain to potato glucose agar (PDA) culture medium, activating for 4d, scraping fresh hyphae, transferring to PDA culture medium covered with glass paper, and scraping fresh hyphae on the glass paper for DNA extraction after 5 d. Since sclerotium rolfsii produces a large amount of extracellular polysaccharide and DNA extraction is difficult, the experiment refers to a Cetyltrimethylammonium bromide (CTAB) method improved by Liuli and the like for DNA extraction.

3. Sclerotium rolfsii gene analysis

Selecting the concentration range obtained by extraction in the step 2 to be between 50 and 150 mu g/mu L, and OD₂₆₀/OD₂₈₀DNA samples ranging between 1.8-2.0 were subjected to genome sequencing. The PacBio platform is used for whole genome sequencing, genome splicing is carried out by combining the sequencing result of the Illumina platform, and the sclerotinia rolfsii WSH-G01 genome with the size of 38Mb is obtained, wherein the genome comprises 116 Contigs and 42 Scaffolds, and the GC content is 46.51%. Based on the obtained whole genome sequence, the near-source relationship between the sclerotinia rolfsii WSH-G01 and other typical white rot fungi is analyzed according to NCBI retrieval and data processing (figure 1).

Comparing with typical white rot fungus with polysaccharide degradation activity, it is found that the sclerotium rolfsii WSH-G01 is close to Schizophyllum commune and Coprinopsis cinerea okayama relatives, and the exopolysaccharide produced by Schizophyllum commune is highly similar to sclerotium rolfsii gum in structure. After functional annotation of the genes associated with the glucan degrading enzyme of strain WSH-G01, it was found that 200 genes associated with the glucan degrading enzyme were possessed, including 68 genes of the Carbohydrate-binding-domain family, 14 genes of Carbohydrate esterase (Carbohydrate esterase), 82 genes of Glycoside hydrolase (Glycoside hydrolase), 30 genes of Glycoside transferase (Glycoside transferase), and 6 genes of Glycoside lyase (Polysaccharide lyase) (table 1). The result shows that the sclerotinia rolfsii WSH-G01 has the degradation potential of sclerotium rolfsii glue.

TABLE 1 sclerotium rolfsii WSH-G01 polysaccharide degrading enzyme gene distribution

Example 2 enzyme Activity analysis of Sclerotinia sclerotiorum WSH-G01 under different enzyme production systems

Two different culture systems of sclerotium rolfsii shown in Table 2 were designed, and the seed solution of sclerotium rolfsii WSH-G01 cultured according to step 1 of example 1 was inoculated with 5% of inoculum size into a high-yield enzyme system and a low-yield enzyme system, respectively, and cultured under the same environment (30 ℃).

TABLE 2 cultivation systems for different enzymes

The activity of the beta-glucanase in the fermentation process is detected, on the premise of ensuring that the biomass in different culture systems is the same, when the culture is carried out for 3 days, the enzyme activity difference of extracellular beta-glucan hydrolase is obvious, the enzyme activity is hardly detected in a low-yield enzyme culture system, and the enzyme activity of the beta-glucanase in a high-yield culture system reaches 8.62U/mL (figure 2). The method shows that in a high-yield enzyme culture system, the thalli is easy to induce and express polysaccharide hydrolase when polysaccharide is used as a sole carbon source so as to obtain enough energy substances. The design of two culture systems with obviously different enzyme production activities provides a theoretical basis for the excavation of the sclerotinia sclerotiorum glue hydrolase gene.

Example 3 transcriptome sequencing and analysis of Sclerotinia sclerotiorum WSH-G01 in two enzyme production systems

High enzyme activity (HE) and low enzyme activity (LE) samples with obvious enzyme production difference when cultured for 3d in the embodiment 2 are selected, total RNA is extracted respectively, and an original cDNA library is constructed.

Extracting RNA of sclerotium rolfsii: the extraction is carried out according to the extraction method of the column type RNA extraction kit of the biological engineering (Shanghai) corporation.

Construction of a sclerotium rolfsii cDNA library: the reverse transcription operation was performed by using a high-quality sclerotium rolfsii WSH-G01 RNA as a template and referring to the method of a reverse transcription kit of TaKaRa Co.

Sequencing and optimizing the data, and performing sequence analysis by taking the obtained genome as a reference, wherein the alignment rate of the HE sample and the LE sample respectively reaches 69.28% and 70.95%. Finally, 2584 genes (P) with significant differences are screened from 9086 genes by comparing the gene expression level differences of HE and LE samples<0.01&|log₂FC | ≧ 1), wherein 1054 of the expression genes are significantly up-regulated and 1530 of the expression genes are significantly down-regulated.

Functional annotation is carried out on the obtained 2584 significant difference genes by GO enrichment, and 32 GO enriched entries are obtained. As can be seen from fig. 3A, the genes with the most significant enrichment difference have molecular activity functions, and the two types of genes with the highest enrichment ratio have molecular catalytic functions and molecular binding functions. The glucan hydrolase generally has the catalytic activity of glycosidic bond hydrolysis and the substrate binding activity simultaneously in structure, and the significant differential enrichment of the two genes indicates that the sclerotium rolfse genes with differential expression are in samples of two different culture systems. Analysis using KEGG revealed that the differential genes were enriched to 130 Pathway of KEGG, with 21 being significantly enriched, with the most significantly enriched metabolic Pathway being the carbohydrate metabolic Pathway (fig. 3B). The change of the carbon source metabolic pathway of the sclerotinia rolfsii WSH-G01 in different culture systems is probably caused by the fact that hyphae in an HE sample produce more sclerotium rolfsase.

Extracting total RNA of strains in a high-yield enzyme culture system, and constructing a cDNA library by using reverse transcriptase. According to the CDS sequences of 14 hydrolases obtained through prediction, primers are designed to amplify gene fragments of 14 hydrolases, and 10 gene fragments (shown as SQE ID No. 2-11 respectively) are successfully amplified. The 10 obtained fragment DNAs are homologously recombined to a pichia pastoris expression vector pPIC9K, and the pichia pastoris GS115 is transformed by an electrical transformation method after the recombination vector is linearized.

Selecting YPD plate with well-grown single colony up to 2mg/mL G418, screening for His resistant to high concentration G418⁺Transformants, further Mut⁺After type selection, positive transformants were verified by PCR.

The positive transformants were selected and inoculated into a tube containing 2mL YPD medium, cultured at 30 ℃ and 220r/min for 24 hours, transferred at 2% inoculum size to a 250mL shake flask containing 50mL BMGY medium, and cultured at 30 ℃ and 220r/min to OD₆₀₀Centrifuging to collect thallus, washing with normal saline twice, inoculating into 250mL shake flask containing 50mL BMMY culture medium, culturing at 30 deg.C and 220r/min, adding methanol to the culture medium every 24 hr to final concentration of 0.5%, sampling, centrifugingRespectively collecting supernatant and thallus, analyzing the expression amount of target protein and optimal protein harvesting time, and detecting and identifying the expression of recombinant protein by SDS-PAGE and activity experiment.

As a result, as shown in FIG. 4, a total of 10 recombinant strains having an expression ability were obtained. All the extracellular expression proteins were subjected to the measurement of the hydrolase activity using laminarin as a substrate, and it was found that 5 of 10 soluble expressed recombinant enzymes had the laminarin hydrolase activity and were each a β -1, 3-glucanase, and the amino acid sequences were obtained by translation from the gene sequences thereof, respectively, as shown in table 4.

In addition, the dispersity of sclerotium rolfsii gum after enzyme hydrolysis of GME9860 shown in SEQ ID No.1 is higher than that before treatment, which shows that degradation of high molecular weight polysaccharide and generation of part of low molecular weight polysaccharide occur in an enzyme reaction system, so that the molecular weight distribution of polysaccharide becomes wider.
