2.1.1.173 |
Accepted name: |
23S rRNA (guanine2445-N2)-methyltransferase |
Reaction: |
S-adenosyl-L-methionine + guanine2445 in 23S rRNA = S-adenosyl-L-homocysteine + N2-methylguanine2445 in 23S rRNA |
Other name(s): |
ycbY (gene name); rlmL (gene name) |
Systematic name: |
S-adenosyl-L-methionine:23S rRNA (guanine2445-N2)-methyltransferase |
Comments: |
The enzyme methylates 23S rRNA in vitro, assembled 50S subunits are not a substrate [1]. The enzyme specifically methylates guanine2445 at N2 in 23S rRNA. |
