NametRNA(Pro) cmo5UGG modification
TypeSYSTEM
DescriptionThe tRNA methyltransferases CmoA and CmoB, usually encoded by tandem genes, work together to complete a tRNA wobble position modification, uridine-5-oxyacetic acid (cmo5U). This modification was shown to allow a tRNA(Pro) to recognize all four proline codons. This system has a fairly narrow taxonomic range, including E. coli, in which cmoA and cmoB occur but are not essential.
