tRNA(guanine-26,N2-N2) methyltransferase This enzyme is responsible for two methylations of a characteristic guanine of most tRNA molecules. The activity has been demonstrated for eukaryotic and archaeal proteins, which are active when expressed in E. coli, a species that lacks this enzyme. At least one Eubacterium, Aquifex aeolicus, has an ortholog, as do all completed archaeal genomes. [Protein synthesis, tRNA and rRNA base modification] |
