    摘要: The present invention relates to a method for preparing LK8 protein, more precisely, a method for mass-production of LK8 protein using Saccharomyces cerevisiae transformed by a gene coding LK8 protein having angiogenesis inhibiting activity. The transformed strain of the present invention and production processes of LK8 protein are expected to contribute greatly to the commercialization of LK8 protein as a novel angiogenesis inhibitor.

    摘要: Provided is a method for improving secretion efficiency of a recombinant foreign protein in a yeast expression system. The method includes transforming a yeast host with a recombinant foreign gene construct containing a galactose-inducible promoter, a secretion signal sequence and a gene encoding the foreign protein to construct a transformed yeast strain; and culturing the transformed yeast strain under the condition that the activity of the galactose-inducible promoter is controlled. Improved secretion efficiency of the foreign protein can be achieved by decreasing overexpression-induced insoluble precipitation of the recombinant foreign protein suffered by a conventional galactose-inducible promoter-based yeast expression system, via appropriate control of a level of galactose functioning as an inducer of the galactose-inducible promoter in cells. Due to improved secretion efficiency of the recombinant foreign protein, present invention makes a contribution to improvement in productivity of recombinant foreign proteins in the yeast expression system and reduction in production costs.
