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.

D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
