A PF14888 PBP-Tp47_c Penicillin-binding protein Tp47 domain C Domain Domain C is the largest domain in this unusual penicillin-binding protein PBP), Tp47. This domain is mainly characterised by an immunoglobulin fold with two opposing beta-sheets that form the typical barrel-like structure. In contrast to the classical immunoglobulin fold, however, this has an additional beta-strand inserted after strand 3. Also, the strands are connected by rather large loops. Helices are inserted between strands 2 and 3 and between strands 4 and 5. Domain C interacts with domain B via a surface that has a slightly concave, goblet-like shape. Tp47 is unusual in that it displays ?-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 [1].

A PF14889 PBP-Tp47_a Penicillin-binding protein Tp47 domain a Domain 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 ?-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 [1].
