Abstract:
A novel cutinase producing strain is provided to be easy for a high concentration cultivation and secrete and product the cutinase extracellularly. And a method for screening the strain is provided to screen and isolate the cutinase producing strain simply with high speed. A Pseudozyma sp. nov. strain producing cutinase is deposited as a deposition no. KCTC 17482. A method for screening the strain comprises the steps of: (a) measuring the decomposing activity of a strain mixture having lipase activity regarding para-nitro phenyl ester substrates having a fatty acid group; (b) selecting the strains showing the decomposing activity only on the para-nitro phenyl ester substrates having a carbon number of less than 4 of the fatty acid group; (c) culturing the selected strains; and (d) evaluating the cutin decomposing capability of the cultured strains. A composition comprises cutinase produced by the Pseudozyma sp. nov. strain as an effective ingredient. Further, a step of measuring the decomposing activity is performed by measuring an initial substrate decomposing speed.
Abstract:
PURPOSE: An expression vector is provided to be useful in producing and developing proteins for a medical and industrial purpose by inducing an activity expression of a protein difficult to be expressed by a fusion partner, and improving the solubility and an expression rate of an objective protein. CONSTITUTION: An expression vector for producing recombinant proteins includes E. coli phophoglycerate kinase (ePGK) gene or N-domain of E. coli phosphoglycerate kinase (N-ePGK) gene as a fusion partner in an expression vector including an objective protein gene. The objective protein gene, and the ePGK gene or N-ePGK gene as the fusion partner are connected. The objective protein is selected from the group consisting of an antigen, an antibody, a cell receptor, an enzyme, a structural protein, the blood serum and a cell protein.
