Description

Construction and application of diosgenin synthetic strain

Technical Field

The invention belongs to the technical field of biology, and relates to construction and application of a diosgenin synthesis strain.

Background

Steroid compounds are widely distributed in nature and are important components of cell membranes, such as cholesterol common in animals, campesterol, sitosterol and stigmasterol in plants, and ergosterol in lower eukaryotes such as Saccharomyces cerevisiae, and play a vital role in survival of animals and plants. In addition, these steroid compounds can be used for further synthesizing other steroid hormones such as progesterone, vitamin D3, etc. in the living body. Steroid hormones, also known as steroid hormones, are endogenous drugs in humans and have an irreplaceable effect on maintaining human health. Steroid drugs are interesting molecules, and due to the diversity of the structures, the steroid drugs endow the steroid drugs with various pharmacological activities, are mainly applied to the aspects of medical care, have very strong pharmacological actions of resisting infection, allergy, virus and shock, and can improve protein metabolism, recover and strengthen physical strength, induce urination and reduce blood pressure. The sales of steroid hormone drugs in 2011 were statistically higher than $280 billion, accounting for about 6% of the total sales of medicines worldwide; the sales of steroid hormone drugs in 2016 are over $1000 billion, becoming the second largest class of drugs next to antibiotics.

Diosgenin (Diospgenin) is also called Diosgenin, and its structure is shown in figure 1. Since the discovery of diosgenin (diosgenera) contained in the rhizome of dioscorea as a source of steroid hormone drugs in 1940, plant and pharmaceutical specialists have paid great attention to plant research in this genus. The diosgenin has great similarity with steroid hormone medicines in structure, is a basic raw material of the steroid hormone medicines, has the effects of antiallergic, antiviral, antishock and the like, and is called as medicinal gold. The water-soluble steroid saponin and the derivatives thereof have various pharmacological activities such as gastric mucosa protection, anti-inflammatory, anticancer and the like. Along with the continuous expansion of the market demand of steroid hormone, the biosynthesis of precursor dioscin is widely focused, and the current synthesis process of dioscin is mainly a traditional acidolysis method. The yam saponin is finally obtained through a plurality of steps such as crushing, acidolysis, rinsing, extraction, crystallization and the like. The method is influenced by the uncertainty of the planting state of the source plant, namely the yellow ginger, the long period (more than 2 years), serious pollution of the extraction process and other factors, the supply and price of the dioscin have large fluctuation, an efficient, clean and stable steroid compound production mode is urgently expected, and the method can greatly promote the production of the dioscin in China and promote the development of the steroid hormone industry in China if the mode of production from plant extraction to biosynthesis can be changed.

EXAMPLE 4 overexpression of DGCYP90G Using high-copy plasmid, strain LP-BC was obtained

Construction of high-copy plasmid pRS426-URA3-pTEF1-DGCYP90G-tCYC1 by utilizing efficient homologous recombination ability of Saccharomyces cerevisiae

1. Obtaining homologous recombination fragments

First, PCR amplification (method 1) was performed using pRS425 plasmid as a template and primers 425-F and 425-50-tCYC1-R (see Table 7) to obtain fragment 425 (sequence 27), and the gel was recovered for use.

The Saccharomyces cerevisiae BY4742 strain genome is used as a template, primers 425-50-URA3-R and pTEF1-50-URA3-F (see table 7) are used for PCR amplification (1 with the same method), fragments 425-50-URA3-pTEF1-50 (sequence 28) are obtained, and the gel is recovered for later use.

The M3-DGCYP90G plasmid is used as a template, and primers pTEF1-up-F and tCYC1-down-R (see table 7) are used for PCR amplification (1 with the same method) to obtain a fragment pTEF1-DGCYP90G-tCYC1 (sequence 29), and the fragment pTEF 1-DGCYC 90G-tCYC1 is recovered for standby.

2. In vivo homologous recombination in Saccharomyces cerevisiae

Saccharomyces cerevisiae LP-104 strain competence was prepared (method same as example 1 step 3), added with 2. Mu.L of each of the above three fragments, transferred to an electric rotating cup after mixing uniformly, electric shocked for 5.6ms at 2.7kv, added with 1mL of 1M sorbitol, resuscitated at 30℃for 1h, and plated on a screening medium plate (formulation: 0.8% yeast selection medium SD-Ura-His-Leu-Trp,2% glucose, 0.01% Leu.,1.5% agar; each percentage number represents g/100 mL). The conditions of the screening culture are as follows: culturing at 30deg.C for more than 36 hr. 5 single clones were randomly selected and verified with primers 425-50-URA3-R and tCYC1-down-R, the correct size being 3274bp. Designated LP-BC.

Recombinant strain LP-BC is obtained by introducing high copy plasmid pRS426-URA3-pTEF1-DGCYP90G-tCYC1 into Saccharomyces cerevisiae LP-104.

Table 7 shows the primers for high copy plasmid construction

3. Saccharomyces cerevisiae LP-034, LP-074 and LP-085-Vc, LP-104, LP-BC (genotypes see Table 8) fermentation product detection

The method is the same as in step 2 of example 1, and the diosgenin yield is shown in FIG. 4.

The data show that the yield of dioscin from strain LP-074 is extremely low, while the yield of dioscin from strain LP-085, which expresses VcCYP90B27 from resveratrol on the basis of strain LP-074, is significantly increased. Further integrating a yam saponin synthesis module at the rDNA multicopy site, screening a strain LP-104 capable of producing 24.6mg/L yam saponin, further integrating high-copy plasmid, and improving the yam saponin yield to 32.3mg/L by over-expressing DGCYP 90G.

4. Fed-batch fermentation

Specific methods and procedures reference [ Paddon C J, westfall P J, pitera D J, et al high-Level Semi-Synthetic Production of the Potent Antimalarial Artemisinin [ J ]. Nature,2013,496 (7446):528-32 ], or Westfall P J, pitera D J, lenihan J R, et al product of Amorphadiene in Yeast, and Its Conversion to Dihydroartemisinic Acid, precursor to the Antimalarial Agent Artemisinin [ J ]. Proc Natl Acad Sci USA,2012,109 (3): E111-8 ] ], the final yield of diosgenin from LP-BC strain in a 5 liter fermentor was 1.3g/L, and the final OD600 was 401 (see FIG. 5).

The discovery result shows that VcCYP90B27 from rhizoma et radix Veratri has great help in the heterologous production of dioscin by Saccharomyces cerevisiae. In addition, the yield of the yam saponin of the LP-BC strain is the highest yield reported, and lays a solid foundation for biosynthesis of steroid hormone by a one-step method.
