Penicillinase from calf stomach is an enzyme that degrades penicillin by hydrolyzing the cyclic amide bonds in the lactam ring of penicillin, which can inactivate penicillin. Penicillinase from calf stomach can be isolated from penicillin resistant strains. Penicillinase from calf stomach has potential application as a marker for steroid hormone enzyme linked immunosorbent assay.
