Crystal structure of the SpoU Methyltransferase AviRb from Streptomyces viridochromogenes

Template:ABSTRACT PUBMED 15581897

Function

[AVRB_STRVR] Specifically methylates the 2'-O-ribose position of uridine-2479 in 23S ribosomal RNA. Confers resistance to antibiotic avilamycin, an orthosomycin antibiotic.^{[1] [2]}
