EFFECT OF DIFFERENT ALLYLIC DIPHOSPHATES ON THE INITIATION OF NEW RUBBER MOLECULES AND ON CIS-1,4-POLYISOPRENE BIOSYNTHESIS IN GUAYULE (PARTHENIUM ARGENTATUM GRAY)

摘要

Natural rubber biosynthesis is the rubber-particle-bound rubber-transferase-catalyzed cis-1,4-polymerization of isoprene monomers derived from isopentenyl diphosphate (IPP). In addition to IPP, allylic diphosphate is required to initiate new rubber molecules.
