IUBMB Enzyme Nomenclature


Accepted name: trans,polycis-polyprenyl diphosphate synthase [(2Z,6E)-farnesyl diphosphate specific]

Reaction: (2Z,6E)-farnesyl diphosphate + n isopentenyl diphosphate = n diphosphate + trans,polycis-polyprenyl diphosphate (n = 9-11)

Systematic name: (2Z,6E)-farnesyl-diphosphate:isopentenyl-diphosphate cistransferase (adding 9-11 isopentenyl units)

Comments: Highest activity with (2Z,6E)-farnesyl diphosphate as allylic substrate. Broad product specificity with the major product being dodecaprenyl diphosphate. Synthesizes even C70 prenyl diphosphate as the maximum chain-length product [1].
