title: Isolation and characterization of proteases from Bacteroides melaninogenicus.
abstract: We isolated two types of intracellular proteases from a strain of Bacteroides melaninogenicus. These enzymes were extracted from cells by ultrasonic treatment and were partially purified. These two enzymes (proteases I and II) differed in molecular weight, heat stability, sensitivity to reducing agents, Km value, and optimum pH for activity.
