Structure of a TrmA–RNA complex: A consensus RNA fold contributes to substrate selectivity and catalysis in m(5)U methyltransferases
TrmA catalyzes S-adenosylmethionine (AdoMet)-dependent methylation of U54 in most tRNAs. We solved the structure of the Escherichia coli 5-methyluridine (m(5)U) 54 tRNA methyltransferase (MTase) TrmA in a covalent complex with a 19-nt T arm analog to 2.4-Å resolution. Mutation of the TrmA catalytic...
