Family

Outer membrane porin, bacterial (IPR005318)

Short name: OM_porin_bac

Family relationships

None.

Description

This family contains bacterial outer membrane porins with serine protease activity [PMID: 9636669]. The serine peptidase domain belongs to MEROPS peptidase family S43 (clan PA(S)).

However many of these proteins are not peptidases and are classified as 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 of peptidases in the S43 family. The putative role of these protein could be to bind ligands and to facilitate the diffusion through the outer membrane.
