This entry represents peptidoglycan binding domain (PGBD), as well as related domains that share the same structure. PGBD may have a general peptidoglycan binding function, has a core structure consisting of a closed, three-helical bundle with a left-handed twist. It is found at the N or C terminus of a variety of enzymes involved in bacterial cell wall degradation [PubMed9555893, PubMed7121588, PubMed1683402]. Examples are:

  • Muramoyl-pentapeptide carboxypeptidase
  • N-acetylmuramoyl-L-alanine amidase cwlA precursor (cell wall hydrolase, autolysin, )
  • Autolytic lysozyme (1,4-beta-N-acetylmuramidase, autolysin, )
  • Membrane-bound lytic murein transglycosylase B
  • Zinc-containing D-alanyl-D-alanine-cleaving carboxypeptidase, VanX [PubMed6743245].

Many of the proteins having this domain are as yet uncharacterised. However, some are known to belong to MEROPS peptidase family M15 (clan MD), subfamily M15A metallopeptidases. A number of the proteins belonging to subfamily M15A are non-peptidase homologues as they either have been found experimentally to be without peptidase activity, or lack amino acid residues that are believed to be essential for the catalytic activity.

Eukaryotic enzymes can contain structurally similar PGBD-like domains. Matrix metalloproteinases (MMP), which catalyse extracellular matrix degradation, have N-terminal domains that resemble PGBD. Examples are gelatinase A (MMP-2), which degrades type IV collagen [PubMed10190290], stromelysin-1 (MMP-3), which plays a role in arthritis and tumour invasion [PubMed12810425, PubMed12888258], and gelatinase B (MMP-9) secreted by neutrophils as part of the innate immune defence mechanism [PubMed12950257]. Several MMPs are implicated in cancer progression, since degradation of the extracellular matrix is an essential step in the cascade of metastasis [PubMed11956636].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.

Alignments of sequences to 7 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have different domain combinations including a PGBD-like domain.

Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.

Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 7 hidden Markov models representing the PGBD-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
