Since this methodology is laborious and in addition, the ester-linked acetyl moiety is highly labile, it is not surprising that the prevalence of .-acetylated peptidoglycan among the eubacteria is largely unknown.

The observed ratio of DAP incorporation to amino acid incorporation during the division cycle led to the development of a consistent description of peptidoglycan synthesis. It was proposed that

Biosynthesis of Peptidoglycan in ,: Regulation of Transpeptidation by Acceptor Peptidetidases. In contrast to cross-linking enzymes from other bacteria, the transpeptidase from this gram-positive organism is essentially insensitive to inhibition by penicillin (Hammes, 1976). Thus, the target of penicillin in . is different from that identified by Tipper and Strominger (1965) for . an
