Summary: CpeT/CpcT family (DUF1001)
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
CpeT/CpcT family (DUF1001) Provide feedback
This family consists of proteins of proteins belonging to the CpeT/CpcT family. These proteins are around 200 amino acids in length. The proteins contain a conserved motif PYR in the amino terminal half of the protein that may be functionally important. The species distribution of the family is interesting. So far it is restricted to cyanobacteria, cryptomonads and plants. It has been shown that CpcT encodes a bilin lyase responsible for attachment of phycocyanobilin to the beta subunit of phycocyanin .

InterPro entry IPR010404
This entry represents the CpcT/CpeT biliprotein lyase family, which have been shown to covalently attach chromophores to cystiene residue(s) of phycobiliproteins [PUBMED:17895251, PUBMED:16644722]. In the chromatically adapting cyanobacterium Fremyella diplosiphon, the proteins have been shown to be induced by green light, as part of the cpeCDESTR operon [PUBMED:12067341].

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
