Substrates: Trm13p belongs to the RFM superfamily of MTases despite the absence of a significant sequence similarity to previously characterized members of this superfamily. The model reveals residues potentially responsible for cofactor binding, tRNA binding, and catalysis of the 2'-O-methylation reaction. The model suggests a presence of one to three disulfide bonds and/or metal ion binding site next to the substrate binding pocket Products: -
