This domain is found in peptide chain release factors such as RF-1 (Swiss:P07011) and RF-2 (Swiss:P07012), and a number of smaller proteins of unknown function such as Swiss:P40711. 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.
