| Abstract |
Among components alpha, beta, and gamma of penicillin-binding protein 1b, the alpha and gamma components were confirmed to represent the primary gene products by agreement of their N-terminal amino acid sequences with those predicted from the nucleotide sequence of the ponB (penicillin-binding protein 1b) gene with exclusion of the first methionine in each component. The generation of beta occurred primarily after cell disruption, and the simultaneous loss of alpha suggested the conversion of alpha to beta. The N-terminal amino acid sequence analyzed for beta showed that the conversion was due to the removal of 24 amino acids from the N terminus of alpha. |
