Structure and mechanism of the RNA triphosphatase component of mammalian mRNA capping enzyme

The 5′ capping of mammalian pre-mRNAs is initiated by RNA triphosphatase, a member of the cysteine phosphatase superfamily. Here we report the 1.65 Å crystal structure of mouse RNA triphosphatase, which reveals a deep, positively charged active site pocket that can fit a 5′ triphosphate end. Structu...
