This entry represents the NUDIX hydrolase domain of U8 snoRNA -decapping enzyme from Xenopus laevis (Nudt16) and similar proteins from animals and bacteria. Nudt16 was initially described as an RNA-binding and decapping enzyme but it was later reported to be specialised in the removal of hazardous (deoxy)inosine diphosphate from the nucleotide pool. It adopts a canonical NUDIX fold, an alpha-beta-alpha sandwich constituted by two beta-sheets whose strands interact in a way that could also be described as a single extended beta-sheet [1].	Domain
