SCO1/SenC Provide feedback
This family is involved in biogenesis of respiratory and photosynthetic systems. SCO1 (P23833) is required for a post-translational step in the accumulation of subunits COXI and COXII of cytochrome c oxidase . SenC (Q52720) is required for optimal cytochrome c oxidase activity and maximal induction of genes encoding the light-harvesting and reaction centre complexes of R. capsulatus .

This family is involved in biogenesis of respiratory and photosynthetic systems.
In yeast the SCO1 protein is specifically required for a post-translational step in the accumulation of subunits 1 and 2 of cytochrome c oxidase (COXI and COX-II) [PUBMED:1944230]. It is a mitochondrion-associated cytochrome c oxidase assembly factor. The SCOP homologue in Bacillus subtilis is also required for the expression of cytochrome c oxidase [PUBMED:10837475].
The purple nonsulphur photosynthetic eubacterium Rhodobacter capsulatus is a versatile organism that can obtain cellular energy by several means, including the capture of light energy for photosynthesis as well as the use of light-independent respiration, in which molecular oxygen serves as a terminal electron acceptor. The SenC protein is required for optimal cytochrome c oxidase activity in aerobically grown R. capsulatus cells and is involved in the induction of structural polypeptides of the light-harvesting and reaction centre complexes [PUBMED:7592491].

This clan contains families related to the thioredoxin family. Thioredoxins are small enzymes that are involved in redox reactions via the reversible oxidation of an active centre disulfide bond. The thioredoxin fold consists of a 3 layer alpha/beta/alpha sandwich and a central beta sheet.

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the SCO1-SenC domain has been found. There are 30 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
