pfam14889: PBP-Tp47_a (This model is not part of the current CDD release)
Penicillin-binding protein Tp47 domain a
This is the first domain in this unusual penicillin-binding protein PBP), Tp47 is mainly composed of beta-strands and is sequentially non-contiguous. The first three domains in Tp47 interact with each other through intimate domain-domain interfaces. Domain A contacts domain B through its N-terminal segment. Domain A also interacts tightly with domain C, Tp47 is unusual in that it displays beta-lactamase activity, and thus it does not fit the classical structural and mechanistic paradigms for PBPs, and thus Tp47 appears to represent a new class of PBP.
