General Information

General Information Comment Organism
physiological function isoform SPS2 weakly complements the yeast coq1 disruptant, which does not form ubiquinone. Transformants produce ubiquinone 9 instead of the native yeast product ubiquinone 6. SPS2 is involved in providing solanesyl diphosphate for plastochinone-9 formation Oryza sativa
