32-203 7.48e-73

Five transmembrane core domain of membrane protein insertase YidC, Alb3, and similar proteins; This group is composed of the bacterial and chloroplastic members of the YidC/Oxa1/Alb3 protein family of insertases, including bacterial YidC, and chloroplastic ALBINO3 (Alb3) and Alb3-like proteins such as ALBINO3-like protein 1 (also called Alb4). Membrane protein insertase YidC, also called foldase YidC or membrane integrase YidC, facilitates proper folding, insertion, and assembly of inner membrane proteins and complexes. Depending on the nature of the substrate, YidC functions in a Sec-independent (YidC only) or a Sec-dependent manner as part of a complex containing YidC, the SecYEG channel, and SecDFYajC. YidC from Gram-negative bacteria contains an extra transmembrane segment (TM1) at the N-terminus and a large periplasmic domain, located between TM1 and TM2, that adopts a beta-super sandwich fold that is found in sugar-binding proteins such as galactose mutarotase. Alb3 and Alb3-like proteins are required for the post-translational insertion of the light-harvesting chlorophyll-binding proteins (LHCPs) into the chloroplast thylakoid membrane. Alb3 acts independently and may also function cooperatively with the thylakoid cpSecYE translocase to insert proteins co-translationally into the thylakoid membrane, similar to bacterial YidC that can function with the SecYEG translocase. YidC/Oxa1/Alb3 family insertases contain a core domain of five transmembrane (5TM) segments that is essential to insertase function.

30-203 1.48e-70

membrane protein insertase, YidC/Oxa1 family, C-terminal domain; 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.

membrane protein insertase, YidC/Oxa1 family, C-terminal domain; 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.

32-203 2.36e-41

Five transmembrane core domain of YidC/Oxa1/Alb3 protein family of insertases; The YidC/Oxa1/Alb3 protein family of insertases facilitate the insertion, folding and assembly of proteins of the inner membranes of bacteria and mitochondria, and the thylakoid membrane of plastids. Members include bacterial YidC, mitochondrial Cox18 and Oxa1, and chloroplastic Alb3 and Alb4. Membrane protein insertase YidC, also called foldase YidC or membrane integrase YidC, facilitates proper folding, insertion, and assembly of inner membrane proteins and complexes. Oxa1 and Cox18/Oxa2 mediate the insertion of both mitochondrion-encoded precursors and nuclear-encoded proteins from the matrix into the mitochondrial inner membrane. Alb3 and Alb3-like proteins, including Alb4, are required for the post-translational insertion of the light-harvesting chlorophyll-binding proteins (LHCPs) into the chloroplast thylakoid membrane. YidC/Oxa1/Alb3 family insertases contain a core domain of five transmembrane (5TM) segments that is essential to insertase function.

34-203 6.59e-39

Five transmembrane core domain of mitochondrial inner membrane protein Oxa1 and similar proteins; This group is composed mostly of the mitochondrial members of the YidC/Oxa1/Alb3 protein family of insertases, including mitochondrial inner membrane proteins Oxa1, Oxa1-like (Oxa1L), cytochrome c oxidase assembly protein 18 (Cox18, also called Oxa2), and Arabidopsis thaliana mitochondrial ALBINO3-like protein 3 (ALB33). It also includes Arabidopsis thaliana chloroplastic ALBINO3-like protein 2 (ALB32). Members of this group mediate the insertion of both mitochondrion-encoded precursors and nuclear-encoded proteins from the matrix into the mitochondrial inner membrane. Oxa1 and Cox18/Oxa2 are essential for the activity and assembly of cytochrome c oxidase, playing central roles in the translocation and export of the N-terminal and C-terminal parts, respectively, of the COX2 protein into the mitochondrial intermembrane space. ALB32 may be involved in the insertion of integral membrane proteins into the chloroplast thylakoid membranes. YidC/Oxa1/Alb3 family insertases contain a core domain of five transmembrane (5TM) segments that is essential to insertase function.
