ID 2.5.1.88 DE Trans,polycis-polyprenyl diphosphate synthase ((2Z,6E)-farnesyl DE diphosphate specific). CA (2Z,6E)-farnesyl diphosphate + n isopentenyl diphosphate = n diphosphate CA + trans,polycis-polyprenyl diphosphate (n = 9-11). CC -!- Highest activity with (2Z,6E)-farnesyl diphosphate as allylic CC substrate. CC -!- Broad product specificity with the major product being dodecaprenyl CC diphosphate. CC -!- Synthesizes even C(70) prenyl diphosphate as the maximum chain-length CC product. DR Q47RM6, DPDP_THEFY ; //
