the direct detection of the products of protease degradation of a susceptible form of penicillinase provides strong evidence that , in stripped protoplasts of b. licheniformis 749/c , penicillinase synthesis continues in the presence of trypsin or chymotrypsin and that , in these modified membranes , the protease is able to act on an early form of the enzyme that has not yet attained the protease-resistant conformation characteristic of the membrane-bound and exopenicillinases .
