Accepted name: 23S rRNA (adenine2030-N6)-methyltransferase
Reaction: S-adenosyl-L-methionine + adenine2030 in 23S rRNA = S-adenosyl-L-homocysteine + N6-methyladenine2030 in 23S rRNA
Other name(s): YhiR protein; rlmJ (gene name); m6A2030 methyltransferase
Systematic name: S-adenosyl-L-methionine:23S rRNA (adenine2030-N6)-methyltransferase
Comments: The recombinant RlmJ protein is most active in methylating deproteinized 23S ribosomal subunit, and does not methylate the completely assembled 50S subunits [1].
