Fig. 3From: Immobilization of E. coli expressing γ-glutamyltranspeptidase on its surface for γ-glutamyl compound productionThe transpeptidation (gray bar) and the hydrolysis (white bar) activities of the immobilized cells of SH2161 expressing GGT on the extracellular surface were assayed using 100 mM CaCl2, with and without 3% NaCl. Values are expressed as the averages of three samples ± standard deviations. The activity without NaCl is taken from Fig. 2Back to article page
