Reaction: prenyl diphosphate + 3 (3-methylbut-3-en-1-yl diphosphate) = 3 diphosphate + nerylneryl diphosphate
(1a) prenyl diphosphate + 3-methylbut-3-en-1-yl diphosphate = diphosphate + neryl diphosphate
(1b) neryl diphosphate + 3-methylbut-3-en-1-yl diphosphate = diphosphate + (2Z,6Z)-farnesyl diphosphate
(1c) (2Z,6Z)-farnesyl diphosphate + 3-methylbut-3-en-1-yl diphosphate = diphosphate + nerylneryl diphosphate
