ABSTRACT The l,d-transpeptidase Ldtfm catalyzes peptidoglycan cross-linking in β-lactam-resistant mutant strains of Enterococcus faecium. Here, we show that in Escherichia coli Ldtfm homologues are responsible for the attachment of the Braun lipoprotein to murein, indicating that evolutionarily related domains have been tailored to use muropeptides or proteins as acyl acceptors in the l,d-transpeptidation reaction.
