== Publication Abstract from PubMed ==
One of the modified nucleosides that frequently occurs in rRNAs and tRNAs is 5-methylcytidine (m(5)C). Escherichia coli Fmu/RsmB/RrmB is an S-adenosyl-L-methionine (AdoMet)-dependent methyltransferase that forms m(5)C967 in 16S rRNA. Fmu/RsmB/RrmB homologues exist not only in bacteria but also in archaea and eukarya and constitute a large orthologous group in the RNA:m(5)C methyltransferase family. In the present study, the crystal structure of a homologue of E. coli Fmu/RsmB/RrmB from the archaeon Pyrococcus horikoshii (PH0851) complexed with an AdoMet analogue was determined at 2.55 A resolution. The structure and sequence of the C-terminal catalytic domain are highly conserved compared with those of E. coli Fmu/RsmB/RrmB. In contrast, the sequence of the N-terminal domain is negligibly conserved between the bacterial and archaeal subfamilies. Nevertheless, the N-terminal domains of PH0851 and E. coli Fmu/RsmB/RrmB are both alpha-helical and adopt a similar topology. Next to the AdoMet-binding site, a positively charged cleft is formed between the N- and C-terminal domains. This cleft is conserved in the archaeal PH0851 homologues and seems to be suitable for binding the RNA substrate.
