| Abstract: | The pro-transglutaminase(pro-TG) gene was obtained by PCR amplification using Streptomyces mobaraensis genome DNA as template and subcloned into the expression plasmid pBEP43(+) via pMD18-T vector,then the plasmid was transformed into B.subtilis WB800.After 32 h flask fermentation,pro-TG protein was successfully expressed in the culture broth.Mature-transglutaminase was obtained after cutting the leader peptide by trypsin activation.BSA cross-linking experiment shows that the mature transglutaminase has cro... |
