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-C20 prenyl diphosphates, producing main products that are not decarboxylated .
