title: [Methylation of prokaryotic RNA by S-methyl methionine in in vivo experiments].
abstract: While cultivating the E. coli 113-3 strain on the mineral medium containing S-methyl-(methyl-3H)-methionine, the incorporation of methyl groups into 4S, 16S and 23S RNA proved to be over 5 times more effective as compared with the control, when L-(methyl-3H)-methionine acted as a donor of methyl groups. The ratio of methylated components has much in common and significant differences. All the types of RNA of E. coli grown in the mineral medium containing S-methyl methionine showed an increased ratio of m2G as compared with the corresponding types of RNA of E. coli after its cultivation in the methionine containing mineral medium.
