Transfer RNAs are synthesized as a primary transcript that is processed to produce a mature tRNA. As part of the maturation process, a subset of the nucleosides are modified. Modifications in the anticodon region often modulate the decoding ability of the tRNA. At position 34, the majority of yeast cytosolic tRNA species that have a uridine are modified to 5-carbamoylmethyluridine (ncm(5)U), 5-carbamoylmethyl-2'-O-methyluridine (ncm(5)Um), 5-methoxycarbonylmethyl-uridine (mcm(5)U) or 5-methoxycarbonylmethyl-2-thiouridine (mcm(5)s(2)U). The formation of mcm(5) and ncm(5) side chains involves a complex pathway, where the last step in formation of mcm(5) is a methyl esterification of cm(5) dependent on the Trm9 and Trm112 proteins.
