2BH2 - PubMed Abstract: 
A single base (U1939) within E. coli 23S ribosomal RNA is methylated by its dedicated enzyme, RumA. The structure of RumA/RNA/S-adenosylhomocysteine uncovers the mechanism for achieving unique selectivity. The single-stranded substrate is "refolded" on the enzyme into a compact conformation with six key intra-RNA interactions ...
