“…The temperature giving 50% residual activities of the AAG and NAGs were 72°C and 52°e, respectively, which were consistent with the previous results. 29 ) Table III shows the effects of various metal ions (1 mM) on the AAG and NAG activities. For the AAG, no or less than 5% inhibition was observed by Fe 2 +, Cu 2 +, Zn 2 +, Ca 2 +, Mg2+, and Cd 1 +, and the 10-15 % inhibition was by Se 2 +, Sb 2 +, Co 2 +, NF +, Li +, Pb 2 +, and Sr2 +.…”
