The PRC-barrel is a partly opened all-beta barrel domain of approximately 80 residues long, which is found in several bacterial, archaeal and plant proteins.
The PRC-barrel domain is found in subunit H of the photosynthetic reaction centre (PRC) in purple bacteria. PRC is an integral membrane pigment-protein complex that carries out light-driven electron transfer reactions during photosynthesis. At the core of the reaction centre is a collection of light-harvesting cofactors and closely associated polypeptides. The core protein complex is made of L, M and H polypeptide subunits . The H subunit has a single transmembrane helix and a large cytoplasmic domain . The core of the cytoplasmic domain contains the PRC-barrel.
A PRC-barrel domain is also present at the C terminus of the pan-bacterial protein RimM, which is involved in ribosomal maturation and processing of 16S rRNA. A family of small proteins conserved in all known euryarchaea are composed entirely of a single stand-alone copy of the domain

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry
out SCOP domain assignments to all genomes at the superfamily level.
Alignments of sequences to 6 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.
Browse and view proteins in genomes which have
different domain combinations including a PRC-barrel domain domain.
Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
There are 6 hidden Markov models representing the PRC-barrel domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
