Enzyme Information

2.1.1.187
23S rRNA (guanine(745)-N(1))-methyltransferase.
based on mapping to UniProt P36999
S-adenosyl-L-methionine + guanine(745) in 23S rRNA = S-adenosyl-L- homocysteine + N(1)-methylguanine(745) in 23S rRNA.
-!- The enzyme specifically methylates guanine(745) at N(1) in 23S rRNA. -!- Formerly EC 2.1.1.51.
