2e5x is a 1 chain structure with sequence from Pyrococcus horikoshii. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
[NTPA_PYRHO] Pyrophosphatase that hydrolyzes non-canonical purine nucleotides such as XTP and ITP/dITP to their respective monophosphate derivatives. Might exclude non-canonical purines from DNA precursor pool, thus preventing their incorporation into DNA and avoiding chromosomal lesions (Probable).[1]
