EC | 2.5.1.117 | ||||||
Accepted name: | homogentisate solanesyltransferase | ||||||

Glossary: | 2-methyl-6-all-trans-nonaprenylbenzene-1,4-diol = 2-methyl-6-solanesylbenzene-1,4-diol = MSBQ | ||||||
Other name(s): | HST; PDS2 (gene name) | ||||||
Systematic name: | all-trans-nonaprenyl-diphosphate:homogentisate nonaprenyltransferase | ||||||
Comments: | Requires Mg2+ for activity. Part of the biosynthesis pathway of plastoquinol-9. The enzymes purified from the plant Arabidopsis thaliana and the alga Chlamydomonas reinhardtii are also active in vitro with unsaturated C10 to C20 prenyl diphosphates, producing main products that are not decarboxylated [2]. | ||||||
