structure in complex with cofactor SAM, to 2.2 A resolution. RsmI consists of an N-terminal putative RNA-binding domain and a C-terminal catalytic domain with a Rossmann-like fold, and belongs to the class III MTase family. SAM is specifically bound into a negatively charged deep pocket formed by both domains by making extensive contacts. Residues Asp100 and Ala124 are vital for SAM-binding. A base-flipping mechanism of the substrate RNA is possible
