摘要：

Evidence is given for the formation of an intermediary complex following the Michaelis complex in galactoside hydrolysis catalyzed by β-galactosidase. A two step scheme is proposed. The formation of the intermediary complex is the limiting step in phenylgalactoside hydrolysis, while each of the two steps is partially rate controlling in o-nitrophenylgalactoside hydrolysis. © 1969.
