Reaction: S-adenosyl-L-methionine + adenosine1067 in 23S rRNA = S-adenosyl-L-homocysteine + 2'-O-methyladenosine1067 in 23S rRNA
Other name(s): 23S rRNA A1067 2'-methyltransferase; thiostrepton-resistance methylase; nosiheptide-resistance methyltransferase
Systematic name: S-adenosyl-L-methionine:23S rRNA (adenosine1067-2'-O)-methyltransferase
Comments: The methylase that is responsible for autoimmunity in the thiostrepton producer Streptomyces azureus, renders ribosomes completely resistant to thiostrepton .
