Protein Family Models

The PRC-barrel is an all beta barrel domain found in photosystem reaction centre subunit H of the purple bacteria and RNA metabolism proteins of the RimM group. PRC-barrels are approximately 80 residues long, and found widely represented in bacteria, archaea and plants. This domain is also present at the carboxyl 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 [1]. [1]. 12429060.

Members of this family belong to the broader family of PRC-barrel domain proteins (see Pfam model PF05239), but are found only in endospore-forming bacteria of the Firmicutes lineage. Most such species have exactly two members of this family and all have at least one; the function is unknown. One of two members from Bacillus subtilis, YmxH, is strongly induced by the mother cell-specific sigma-E factor.
