It has been reported that neutral salts such as NaCl activate the thermolysin-catalyzed hydrolysis of substrates containing glycine at the P1 position (carboxylic side of the cleavage bond) [Holmquist, B. & Vallee, B.L. (1976) Biochemistry 15, 101-107]. In this paper, we demonstrate that high concentrations (1-4 M) of neutral salts greatly enhance the thermolysin activity in both hydrolysis and synthesis of N-carbobenzoxy-L-aspartyl-L-phenylalanine methyl ester (ZAPM), a precursor of a peptide… CONTINUE READING
