RT "The thiostrepton-resistance-encoding gene in Streptomyces laurentii is
RT located within a cluster of ribosomal protein operons.";
RL Gene 164:137-142(1995).
CC -!- FUNCTION: Specifically methylates the adenosine-1067 in 23S ribosomal
CC RNA. Confers resistance to antibiotic thiostrepton.
CC {ECO:0000250|UniProtKB:P18644}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine(1067) in 23S rRNA + S-adenosyl-L-methionine = 2'-O-
CC methyladenosine(1067) in 23S rRNA + H(+) + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:43212, Rhea:RHEA-COMP:10409, Rhea:RHEA-COMP:10410,

CC Evidence={ECO:0000250|UniProtKB:P18644};
CC -!- SIMILARITY: Belongs to the class IV-like SAM-binding methyltransferase
CC superfamily. RNA methyltransferase TsnR/AvirB family. {ECO:0000305}.
