IntEnz Enzyme Nomenclature


Accepted name:
ditrans,polycis-undecaprenyl-diphosphate synthase [(2E,6E)-farnesyl-diphosphate specific]
Other names:
ditrans,polycis-undecaprenyl-diphosphate synthase
UPP synthetase
bactoprenyl-diphosphate synthase
undecaprenyl diphosphate synthetase
undecaprenyl pyrophosphate synthetase
undecaprenyl-diphosphate synthase
undecaprenyl pyrophosphate synthase
Systematic name:
(2E,6E)-farnesyl-diphosphate:isopentenyl-diphosphate cistransferase (adding 8 isopentenyl units)



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 [3].
