In enzymology a rubber cis-polyprenylcistransferase (EC 2.5.1.20) is an enzyme that catalyzes the chemical reactionpoly-cis-polyprenyl diphosphate + isopentenyl diphosphate diphosphate + a poly-cis-polyprenyl diphosphate longer by one C5 unitThus the two substrates of this enzyme are poly-cis-polyprenyl diphosphate and isopentenyl diphosphate whereas its two products are diphosphate and poly-cis-polyprenyl diphosphate longer by one C5 unit.This enzyme belongs to the family of transferases specifically those transferring aryl or alkyl groups other than methyl groups.
