    摘要: The present invention relates to a method for separating and purifying a target protein, a method for preparing a target protein, and a method for bioconversion by a whole cell enzyme or a partially purified enzyme. According to the present invention, when the sHSPs are added in cultivation, separation and purification processes for preparing a target protein, the target protein can be obtained at high yields by preventing the loss of protein by proteases. Also, when sIISPs are added in a reaction process using a whole cell enzyme or a partially purified enzyme, the yield of bioconversion using enzyme can be increased by preventing the loss of enzyme by proteases.

    摘要: A method for producing target proteins by deleting or amplifying ibpA and/or ibpB genes coding for inclusion body-associated proteins. Two methods for producing target proteins using ibpA and/or ibpB genes coding for inclusion body-associated proteins of E. coli are described. The first method enhances the secretory production and activity of target proteins using ibpA and/or ibpB genes-deleted bacteria. The second method enhances the production of target proteins in the cytoplasm and also converts the target proteins from soluble form to insoluble inclusion body, using ibpA and/or ibpB gene-amplified bacteria.

    摘要: The present invention relates to a composition containing sHSPs for prevention of protein degradation and a composition for two-dimensional (2-D) gel electrophoresis. Furthermore, the present invention relates to the improved method of 2-D gel electrophoresis, which is characterized by using sHSPs. According to the present invention, decreasing of protein spots was prevented in the 2-D gel electrophoresis, thereby obtaining 2-D gel with much more protein spots.
