plaunotol = 18-hydroxygeranylgeraniol
geranylgeranyl diphosphate phosphatase
Involved in the biosynthesis of plaunotol. There are two isoenzymes with different ion requirements. Neither require Mg2+ but in addition PII is inhibited by Zn2+, Mn2+ and Co2+. It is not known which isoenzyme is involved in plaunotol biosynthesis.
