comparison of the action of highly purified pepsinlike enzymes ( rhizopus proteinase , mucor proteinase , rennin ) with that of swine pepsin a indicates significant differences among them , either in the binding of the substrate ( as estimated by k ( m ) ) , or in the catalytic efficiency ( as measured by k ( cat ) ) , or both .
