Molecular cloning and expression of a mammalian homologue of a translationally controlled tumor protein (TCTP) gene from Penaeus monodon shrimp

We previously observed secretion of native-type Streptomyces mobaraensis transglutaminase (MTGase) in Corynebacterium glutamicum by co-expressing the subtilisin-like protease SAM-P45 from S. albogriseolus which processes the pro-region. In the present study, we have used a chimeric pro-region consisting of S. mobaraensis and Streptomyces cinnamoneus transglutaminases for the production of MTGase in C. glutamicum. As a result, secretion of MTGase using the chimeric pro-region is increased compared to that using the native pro-region.
