Enzyme Information

2.1.1.190
23S rRNA (uracil(1939)-C(5))-methyltransferase.
based on mapping to UniProt P55135
S-adenosyl-L-methionine + uracil(1939) in 23S rRNA = S-adenosyl-L- homocysteine + 5-methyluracil(1939) in 23S rRNA.
-!- The enzyme specifically methylates uracil(1939) at C(5) in 23S rRNA. -!- The enzyme contains an [4Fe-4S] cluster coordinated by four conserved cysteine residues.
