ID   3.1.7.5
DE   geranylgeranyl diphosphate diphosphatase.
AN   geranylgeranyl diphosphate phosphatase.
CA   (2E,6E,10E)-geranylgeranyl diphosphate + H2O = (2E,6E,10E)-
CA   geranylgeraniol + diphosphate.
CC   -!- Involved in the biosynthesis of plaunotol.
CC   -!- There are two isoenzymes with different ion requirements.
CC   -!- Neither require Mg(2+) but in addition PII is inhibited by Zn(2+),
CC       Mn(2+) and Co(2+).
CC   -!- It is not known which isoenzyme is involved in plaunotol
CC       biosynthesis.
