Abstract

SUMMARY: Extracellular penicillinases produced by ATCC 9945A and from the same structural gene, , were compared. The two strains secreted the same exolarge penicillinase (mol. wt, 30500; isoelectric point, pI = 5.00-5.04; NH-terminal amino acid, Ser). In contrast, the exo-small enzyme from (mol. wt, 29500; pI = 5.00-5.04; NH-terminal amino acid, Glu or Asn) was slightly different from that of (mol. wt, 29500; pI = 5.13; NH-terminal amino acid, Lys). The difference in the NH-terminal residue is most probably due to differences in degradation by host-specific proteolytic enzymes.
