SCO1/SenC; This family is involved in biogenesis of respiratory and photosynthetic systems. SCO1 is required for a post-translational step in the accumulation of subunits COXI and COXII of cytochrome c oxidase. SenC is required for optimal cytochrome c oxidase activity and maximal induction of genes encoding the light-harvesting and reaction centre complexes of R. capsulatus.

 50-191 9.23e-58

SCO (an acronym for Synthesis of Cytochrome c Oxidase) family; composed of proteins similar to Sco1, a membrane-anchored protein possessing a soluble domain with a TRX fold. Members of this family are required for the proper assembly of cytochrome c oxidase (COX). They contain a metal binding motif, typically CXXXC, which is located in a flexible loop. COX, the terminal enzyme in the respiratory chain, is imbedded in the inner mitochondrial membrane of all eukaryotes and in the plasma membrane of some prokaryotes. It is composed of two subunits, COX I and COX II. It has been proposed that Sco1 specifically delivers copper to the CuA site, a dinuclear copper center, of the COX II subunit. Mutations in human Sco1 and Sco2 cause fatal infantile hepatoencephalomyopathy and cardioencephalomyopathy, respectively. Both disorders are associated with severe COX deficiency in affected tissues. More recently, it has been argued that the redox sensitivity of the copper binding properties of Sco1 implies that it participates in signaling events rather than functioning as a chaperone that transfers copper to COX II.

 50-184 9.90e-03

TlpA-like family; composed of TlpA, ResA, DsbE and similar proteins. TlpA, ResA and DsbE are bacterial protein disulfide reductases with important roles in cytochrome maturation. They are membrane-anchored proteins with a soluble TRX domain containing a CXXC motif located in the periplasm. The TRX domains of this family contain an insert, approximately 25 residues in length, which correspond to an extra alpha helix and a beta strand when compared with TRX. TlpA catalyzes an essential reaction in the biogenesis of cytochrome aa3, while ResA and DsbE are essential proteins in cytochrome c maturation. Also included in this family are proteins containing a TlpA-like TRX domain with domain architectures similar to E. coli DipZ protein, and the N-terminal TRX domain of PilB protein from Neisseria which acts as a disulfide reductase that can recylce methionine sulfoxide reductases.
