| 2 S-adenosyl-L-methionine + adenine2085 in 23S rRNA | since methyl groups are incorporated in protein-free 23S rRNA molecules, the structure of rRNA alone must contain sufficient information to specify the methylation site. Highest incorporation is obtained with Bacillus subtilis 23S rRNA. Escherichia coli 23S rRNA acts as a poorer substrate (35% of the methylation obtained with Bacillus subtilis 23S rRNA) | Bacillus subtilis | 2 S-adenosyl-L-homocysteine + N6-dimethyladenine2085 in 23S rRNA | - |
