Enzyme Commission Summary:
Undecaprenyl pyrophosphate synthase catalyses the consecutive condensation reactions of a farnesyl diphosphate with eight isopentenyl diphosphates, in which new cis-double bonds are formed, to generate undecaprenyl diphosphate that serves as a lipid carrier for peptidoglycan synthesis of bacterial cell wall [Guo05].
