Abstract

Escherichia coli cells showed maximum activity of gamma-glutamyltranspeptidase (EC 2.3.2.2) when they were grown at 20 degrees C, 14% of maximum activity at 37 degrees C, and none at 43 degrees C. The enzyme activity of intact cells grown at 20 degrees C was stably maintained after the temperature was changed to 45 degrees C. The activity increased during the exponential phase, and maximum activity was found at stationary phase. Its intracellular localization in the periplasmic space was confirmed.
