Description

[0001] The present invention relates to an Escherichia coli and a Corynebacterium glutamicum shuttle vector for regulating expression of a gene of interest,

The present invention relates to an Escherichia coli and a Corynebacterium shuttle vector for controlling expression of a target gene, and Escherichia coli and Corynebacterium into which the shuttle vector is introduced.

Corynebacterium glutamicum is a gram-positive strain and is widely used for producing purine-based nucleic acids such as glutamate, lysine, amino acids such as threonine, and inosine acid. Corynebacterium glutamicum is easy to grow, can grow at a concentration as high as four times that of E. coli, and has a low dielectric constant and low probability of mutation. In addition, it is a non-pathogenic strain and has advantages as industrial strains such as not producing spores and not harmful to the environment.

The cloning vector is a loop-like DNA that can be replicated independently of the main chromosome in bacteria. Such a cloning vector includes an origin of replication for maintaining the plasmid in the strain, a selectable marker gene for selecting a strain having the vector, and a multi-cloning site for cloning of the foreign gene -cloning site, MCS).

The shuttle vector generally contains a vector that is sustainable in a plurality of strains. The E. coli-Corynebacterium glutamicum shuttle vector contains both the origin of replication of Escherichia coli and the origin of replication of Corynebacterium glutamicum. By using such a shuttle vector, a desired trait can be easily introduced into a target strain. For example, a gene encoding a foreign gene or a mutation in E. coli can be cloned into a shuttle vector, and the shuttle vector can be introduced into Corynebacterium glutamicum Can also be introduced into humans to induce desired traits.

On the other hand, various gene manipulation techniques for controlling the gene expression of bacteria are known. In order to utilize the CRISPRi (CRISPR interference) system which inhibits the expression of the target gene based on the inactivated Cas9 (dCas9), in the prior art, two kinds of plasmids of dCas9 and the guide RNA of the target gene (sgRNA) Respectively. Therefore, it has been difficult to co-transform the plasmid of dCas9 and two plasmids of sgRNA in order to produce a CRISPRi recombinant strain, and a plasmid capable of inducing overexpression of a specific gene or expressing a foreign gene is additionally added And they could not make various recombinant strains because they could not switch.

For the production of pCoryne-sgRNA-dCas9 without the desired gene, dCas9 was firstly synthesized in two portions of pUC57 vector. Specifically, by inserting tetR-tetO-dCas9-1 of pUC-dCas9-1 (Fig. 2a) into pCoryne-sgRNA-plasmid (Fig. 2c) using BamH I and Pst I restriction enzymes, pCoryne-sgRNA- 1 (Fig. 2d) for making a back, a dCas9-2 of pUC-dCas9-2 (Fig. 2b) the pCoryne-sgRNA - by inserting with the Apa I and Pst I restriction enzyme in dCas9-1 (Fig. 2d) pCoryne -sgRNA-dCas9 (Figure 2e). The DNA sequence of pCoryne-sgRNA-dCas9 according to Figure 2e is shown in SEQ ID NO: For transformation of Escherichia coli, a chemical transformation method using KCM buffer (500 mM KCl, 150 mM CaCl ₂ , and 250 mM MgCl ₂ ) was used, and in the case of Corynebacterium glutamicum, an electric trait using a MicroPulser Electroporator (BioRad) Transformation method was used and transfection was confirmed by colony PCR.

Preparation and Characterization of pCoryne-sgRNA-xylA-r-dCas9

In this example, a shuttle vector using CRISPRi for the xylA gene of Escherichia coli was constructed, and the expression of the xylA gene was regulated according to the shuttle vector. xylA is a gene encoding xylose isomerase of Escherichia coli. It is a gene capable of hydrolyzing D-xylose with D-xylulose to enable cell growth using xylose as a carbon source . A diagram of a shuttle vector (pCoryne-sgRNA-xylA-r-dCas9) that works in E. coli and Corynebacterium glutamicum using CRISPRi for the xylA gene is shown in FIG.

To this end, sgRNA two kinds for the purpose of the xylA gene (sgRNA-xylA-r1: xylA promoter part, sgRNA-xylA-r2 of the gene: Start of the xylA gene codon part) the shuttle vector two kinds with CRISPRi, each including (pCoryne-sgRNA-xylA-r1-dCas9, pCoryne-sgRNA-xylA-r2-dCas9) was prepared and transformed into E. coli.

Two recombinant E. coli strains were cultured in LB medium at 37 ° C and 200 rpm overnight, then inoculated at a ratio of 1: 100 in LB medium supplemented with 0.1% xylose, and cultured at 37 ° C for 27 hours. Then, 100 nM aTc was used for induction at 0 hour, and a sample was obtained at 5 hours. RNA was extracted from this sample to make cDNA, and the amount of xylA expression was confirmed by RT-PCR. The sequence of the primers used in RT-PCR is shown in Table 2 below, and the control group was rssA , a gene of 16S rRNA.

Figure 3a is a strain CRISPRi shuttle vector is the expression of which the xylA purposes in E. coli (WT + pCoryne-sgRNA-xylA -r1-dCas9, WT + pCoryne-sgRNA-xylA-r2-dCas9) and the wild type strain (WT), and (WT + pZ8-0, WT + pCoryne-sgRNA-dCas9), and Fig. 3b shows the results of the growth of E. coli The strains CRISPRi shuttle vector is the expression of for the purpose of xylA (WT + pCoryne-sgRNA- xylA-r1-dCas9, WT + pCoryne-sgRNA-xylA-r2-dCas9) and the wild type strain (WT) and the control strain (WT + pZ8-0, WT + pCoryne-sgRNA-dCas9).

Result, the shuttle vector is introduced in dCas9 and sgRNA-xylA-r1, or sgRNA-xylA-r2 are both expressed strain is the amount of the wild-type strain and growth is slow, was young (Fig. 3a), the expression of xylA compared to the control strain the wild-type strain acn expression level in the rat . (Fig. 3B). In other words, it was confirmed that the shuttle vector of CRISPRi according to the present invention worked well in E. coli and mRNA transcription of xylA was reliably suppressed.

Preparation and Characterization of pCoryne-sgRNA-pyc-r-dCas9

In this example, the pyc < RTI ID = 0.0 > A shuttle vector was constructed using CRISPRi for gene expression and its phenotype was observed. pyc is because of the ability to switch to Corynebacterium as a gene that encodes a pyruvate carboxyl cyclase (pyruvate carboxylase) of glutamicum, configure the reductive branch of the TCA cycle, and oxaloacetic acetate (oxaloacetate) a pyruvate, pyc Is inhibited, Corynebacterium glutamicum does not grow normally. pyc A diagram of a shuttle vector (pCoryne-sgRNA-pyc-r-dCas9) that works in E. coli and Corynebacterium glutamicum using CRISPRi for gene targeting is shown in FIG.

For this purpose, a shuttle vector (pCoryne-sgRNA-pyc-r-dCas9) using CRISPRi containing sgRNA (sgRNA-pyc-r) for pyc gene was transformed into Corynebacterium glutamicum , The recombinant Corynebacterium glutamicum strain was cultured in BHIS medium at 30 ° C. overnight at 200 rpm and then cultured in CgXII medium supplemented with 2% sodium lactate at about OD 1.0 for 34 hours at 30 ° C. Respectively.

FIG. 4 shows that when the expression of pyc gene was inhibited by using pCoryne-sgRNA-dCas9 for transformation of Corynebacterium glutamicum using CRISPRi consisting of one plasmid, the growth of the recombinant strain was inhibited by wild type and control The results are as follows.

As a result, it was observed that the growth of dCas9 and sgRNA-pyc-r-expressing strains was inhibited in comparison with the wild type strain and the control strain in which neither dCas9 nor sgRNA were present or only dCas9 (Fig. 4). In other words, it was confirmed that the shuttle vector of CRISPRi according to the present example works in Corynebacterium glutamicum to suppress the expression of pyc .
