2b3t is a 2 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
PRMC_ECOLI Methylates the class 1 translation termination release factors RF1/PrfA and RF2/PrfB on the glutamine residue of the universally conserved GGQ motif, i.e. on 'Gln-235' in RF1 and on 'Gln-252' in RF2.[1][2][3]
