Name
23S rRNA (adenosine1067-2'-O)-methyltransferase;
23S rRNA A1067 2'-methyltransferase;
thiostrepton-resistance methylase;
nosiheptide-resistance methyltransferase
Class

Sysname
S-adenosyl-L-methionine:23S rRNA (adenosine1067-2'-O)-methyltransferase
Reaction(IUBMB)
S-adenosyl-L-methionine + adenosine1067 in 23S rRNA = S-adenosyl-L-homocysteine + 2'-O-methyladenosine1067 in 23S rRNA
Substrate
S-adenosyl-L-methionine [CPD:C00019];
adenosine1067 in 23S rRNA
Product
S-adenosyl-L-homocysteine [CPD:C00021];
2'-O-methyladenosine1067 in 23S rRNA
Comment
The methylase that is responsible for autoimmunity in the thiostrepton producer Streptomyces azureus, renders ribosomes completely resistant to thiostrepton [2].
