UniProtKB - Q6Q3H2 (TPSVS_VITVI)
Protein
Valencene synthase
Gene
ValCS
Organism
Vitis vinifera (Grape)
Status
Functioni
Involved in the biosynthesis of valencene, a major volatile emitted from flowers of grapevine. Can use farnesyl diphosphate as substrate, but not geranyl diphosphate or geranylgeranyl diphosphate. Produces mainly (+)-valencene and (-)-7-epi-alpha-selinene along with five minor products.

Expressioni
Tissue specificityi
Expressed in flowers and anthers. Detected inside the pollen grains, but not in stems, leaves, tendrils, roots, seeds, pistils or caps.2 Publications
Developmental stagei
Expressed at prebloom in flower buds but barely detectable after anthesis and in early stages of fruit onset. Detected again two months after flowering, then increases and reaches a maximum when the fruit is at peak maturity. Also expressed in very young seeds.2 Publications
