Protein Family Models

This is the periplasmic domain of YidC, a bacterial membrane protein which is required for the insertion and assembly of inner membrane proteins [1,2]. [1]. 18234665. The crystal structure of the periplasmic domain of the Escherichia coli membrane protein insertase YidC contains a substrate binding cleft. Ravaud S, Stjepanovic G, Wild K, Sinning I;.

This model describes full-length from some species, and the C-terminal region only from other species, of the YidC/Oxa1 family of proteins. This domain appears to be univeral among bacteria (although absent from Archaea). The well-characterized YidC protein from Escherichia coli and its close homologs contain a large N-terminal periplasmic domain in addition to the region modeled here.

Essentially all bacteria have a member of the YidC family, whose C-terminal domain is modeled by TIGR03592. The two copies are found in endospore-forming bacteria such as Bacillus subtilis appear redundant during vegetative growth, although the member designated spoIIIJ (stage III sporulation protein J) has a distinct role in spore formation. YidC, its mitochondrial homolog Oxa1, and its chloroplast homolog direct insertion into the bacterial/organellar inner (or only) membrane. This model describes an N-terminal sequence region, including a large periplasmic domain lacking in YidC members from Gram-positive species. The multifunctional YidC protein acts both with and independently of the Sec system.
