Abstract:

Rubber transferase, a cis-prenyltransferase catalyzing the incorporation of isopentenyl pyrophosphate into rubber molecules, is critical to the quality and the yield of natural rubber. However, the identity of the rubber transferase, and the mechanisms related to polymerization and the determination of the molecular mass of natural rubber remain equivocal. This article provides an overview of the rubber transferases of Hevea brasiliensis and other rubber-producing plants from aspects of the biological function, the purification, the characterization, and the regulation of the catalytic activity.

Key words: natural rubber; rubber transferase; rubber-producing plants; Hevea brasiliensis
