: (2E,6E)-farnezil difosfat + 8 [[izopentenil difosfat]] <math>\rightleftharpoons</math> 8 [[difosfat]] + ditrans,oktacis-undekaprenil difosfat

Undekaprenil pirofosfatna sintaza katalizuje konsekutivne reakcije kondenzacije [[farnezil difosfat]]a sa osam izopentenilnih difosfata, u kojima se nove -{cis}--dvostruke veze formiraju. Time se generiše undekaprenil difosfat koji služi kao [[lipid]]ni nosilac za peptidoglikansku sintezu bakterijskog ćelijskog zida.
