Fig. 1From: Immobilization of E. coli expressing γ-glutamyltranspeptidase on its surface for γ-glutamyl compound productionWild-type and cell-surface expressing forms of E. coli GGT. Arg232 is the residue in the fifth extracellular loop of YiaT, but the C-terminal of the wild-type YiaT protein is in the periplasm (Han and Lee 2015). By connecting GGT to the Arg232 residue of YiaT, GGT was expressed on the extracellular surface of E. coli cells (Suzuki and Sasabu 2023)Back to article page
