Synthetic mTG construct used for transformation of E. coli BL21 (DE3) cells. The construct consists of restriction enzyme sites, the pro-domain required for folding and the mTG gene separately expressed. Each one has a preceding PelB sequence to direct periplasm secretion, whereupon folding will occur in the periplasm. Another ribosome binding site (RBS) precedes the mTG gene to ensure proper translation
