| Glossary: |
plaunotol = 18-hydroxygeranylgeraniol |
| Other name(s): |
geranylgeranyl diphosphate phosphatase |
| Systematic name: |
geranyl-diphosphate diphosphohydrolase |
| Comments: |
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. |
