Amino acid residues of the Escherichia coli tRNA(m(5)U54)methyltransferase (TrmA) critical for stability, covalent binding of tRNA and enzymatic activity
The Escherichia coli trmA gene encodes the tRNA(m(5)U54)methyltransferase, which catalyses the formation of m(5)U54 in tRNA. During the synthesis of m(5)U54, a covalent 62-kDa TrmA-tRNA intermediate is formed between the amino acid C324 of the enzyme and the 6-carbon of uracil. We have analysed the...
