Penicillin is an active-site inhibitor for four genera of bacteria.
The hypothesis that penicillin acts as an active-site inhibitor cell wall biosynthesis was tested by a method of partial proteolytic mapping of penicillin-binding sites versus substrate-binding sites in cell wall D-alanine carboxypeptidases. This enzyme was obtained from four genera of bacteria, purified, and tested.
