Enzyme Information
| 3.6.1.17 |
Bis(5'-nucleosyl)-tetraphosphatase (asymmetrical).
based on mapping to UniProt P50583
P(1),P(4)-bis(5'-guanosyl) tetraphosphate + H(2)O = GTP + GMP.
-!- Also acts on bis(5'-xanthosyl)-tetraphosphate and, more slowly, on bis(5'-adenosyl)-tetraphosphate and bis(5'-uridyl)-tetraphosphate (cf. EC 3.6.1.41).
