pfam00472: RF-1 (this model, PSSM-Id:395378 is obsolete and has been replaced by 459823)
RF-1 domain
This domain is found in peptide chain release factors such as RF-1 and RF-2, and a number of smaller proteins of unknown function. This domain contains the peptidyl-tRNA hydrolase activity. The domain contains a highly conserved motif GGQ, where the glutamine is thought to coordinate the water that mediates the hydrolysis.
