Enzyme Information
| 2.1.1.208 |
23S rRNA (uridine(2479)-2'-O)-methyltransferase.
based on mapping to UniProt Q9F5K6
S-adenosyl-L-methionine + uridine(2479) in 23S rRNA = S-adenosyl-L- homocysteine + 2'-O-methyluridine(2479) in 23S rRNA.
-!- Streptomyces viridochromogenes produces the antibiotic avilamycin A which binds to the 50S ribosomal subunit to inhibit protein synthesis. -!- To protect itself from the antibiotic, Streptomyces viridochromogenes utilizes two methyltransferases, 23S rRNA (uridine(2479)-2'-O)- methyltransferase and EC 2.1.1.209 whose actions confer avilamycin resistance to the RNA.
