Synopsis: Three structures of a putative RNA 5-methyluridine methyltransferase from T. thermophilus, including its complex with S-adenosyl-L-homocysteine, are presented. The structures reveal the mode of cofactor binding, architecture of the putative active site, and the presence of a deep cleft adjacent to the active site that may bind RNA.
