Accepted name: (2Z,6Z)-farnesyl diphosphate synthase
Reaction: dimethylallyl diphosphate + 2 isopentenyl diphosphate = 2 diphosphate + (2Z,6Z)-farnesyl diphosphate
(1a) dimethylallyl diphosphate + isopentenyl diphosphate = diphosphate + neryl diphosphate
(1b) neryl diphosphate + isopentenyl diphosphate = diphosphate + (2Z,6Z)-farnesyl diphosphate
Other name(s): cis,cis-farnesyl diphosphate synthase; Z,Z-FPP synthase; zFPS; Z,Z-farnesyl pyrophosphate synthase
Systematic name: dimethylallyl-diphosphate:isopentenyl-diphosphate cistransferase (adding 2 isopentenyl units)
Comments: This enzyme, originally characterized from wild tomato, specifically forms (2Z,6Z)-farnesyl diphosphate via neryl diphosphate and isopentenyl diphosphate. In wild tomato it is involved in the biosynthesis of several sesquiterpenes. See also EC [(2Z,6E)-farnesyl diphosphate synthase] and EC [(2E,6E)-farnesyl diphosphate synthase].
