Microbial transglutaminases(MTG)are a family of enzymes that catalyze post-translational modification of proteins by inter or intra-molecular crosslinking through acyl-transfer reaction.Because of the modification of protein functional properties,MTG showed a broad range of applications in the food industry,biomedicine and textile industry.In this paper,correlation techniques,research progress of constructing engineered strains which can produce microbial transglutaminase were reviewed and direction of futu...
