Members of this family are probably proteases (after a isoprenyl group is attached to the Cys residue in the C-terminal CAAX motif of a protein to attach it to the membrane, the AAX tripeptide being removed by one of the CAAX prenyl proteases). The family contains the CAAX prenyl protease. The proteins contain a highly conserved Glu-Glu motif at the amino end of the alignment. The alignment also contains two histidine residues that may be involved in zinc binding. While they are involved in membrane anchoring of proteins in eukaryotes, little is known about their function in prokaryotes. In some known bacteriocin loci, Abi genes have been found downstream of bacteriocin structural genes where they are probably involved in self-immunity. Investigation of the bacteriocin-like loci in the Gram positive bacteria locus from Lactobacillus sakei 23K confirmed that the bacteriocin-like genes (sak23Kalphabeta) exhibited antimicrobial activity when expressed in a heterologous host and that the associated Abi gene (sak23Ki) conferred immunity against the cognate bacteriocin. Interestingly, the immunity genes from three similar systems conferred a high degree of cross-immunity against each other's bacteriocins, suggesting the recognition of a common receptor. Site-directed mutagenesis demonstrated that the conserved motifs constituting the putative proteolytic active site of the Abi proteins are essential for the immunity function of Sak23Ki - thus a new concept in self-immunity.

The CAAX prenyl protease, in eukaryotes, catalyzes three covalent modifications, including cleavage and acylation, at the C-terminus of certain proteins in a process connected to protein sorting. This family describes a bacterial protein family homologous to one domain of the CAAX-processing enzyme. Members of this protein family are found in genomes that carry a predicted protein sorting system, PEP-CTERM/exosortase, usually in the vicinity of the EpsH homolog that is the hallmark of the system. The function of this protein is unknown, but it may relate to protein motification.

>PF02517 Abi: CAAX protease self-immunity; InterPro: IPR003675 Members of this family are probably proteases (after a isoprenyl group is attached to the Cys residue in the C-terminal CAAX motif of a protein to attach it to the membrane, the AAX tripeptide is removed by one of the CAAX prenyl proteases) Back     alignment and domain information
