2.5.1.B41 | metabolism |
hexaprenyl diphosphate and heptaprenyl diphosphate, intermediates of two isoprenoid pathways (acyclic terpenes and menaquinones), are biosynthesized by one trifunctional (all-E)-isoprenyl diphosphate synthase, E-IDS. Geranylfarnesyl diphosphate/hexaprenyl diphosphate and heptaprenyl diphosphate are the primary substrates for the biosynthesis of acyclic terpenes and menaquinone-7, respectively. (All-E)-and E,Z-mixed isoprenyl diphosphates are formed by E-IDSs and Z-IDSs, respectively, which have no sequence similarity with each other |
