The 2.05 A crystal structure of yeast REMARK 400 RNA triphosphatase Cet1p reveals a novel active site REMARK 400 fold whereby an 8-strand beta barrel forms a REMARK 400 topologically closed triphosphatase tunnel. REMARK 400 Interactions of a sulfate bound in the center of the REMARK 400 tunnel with a divalent cation and basic amino acids REMARK 400 projecting into the tunnel suggest a catalytic REMARK 400 mechanism that is supported by mutational data. REMARK 400 Discrete surface domains are responsible for Cet1p REMARK 400 homodimerization and Cet1p-binding to the REMARK 400 guanylyltransferase component of the yeast capping REMARK 400 apparatus. The structure and mechanism of the fungal REMARK 400 RAN triphosphatases are completely different from REMARK 400 those of the mammalian mRNA capping enzymes.
