New aspects of rubber biosynthesis
Botanical Journal of the Linnean Society, 1987New aspects of rubber biosynthesis. Following a review of the site of rubber biosynthesis in Hevea brasiliensis and Parthenium argentalum, evidence is given for the initiation of polyisoprene molecules from (ranMerpenoid precursors including geranylgeranyl pyrophosphate.

NATURAL RUBBER BIOSYNTHESIS: STILL A MYSTERY
Rubber Chemistry and Technology, 2018ABSTRACT Currently, Hevea brasiliensis (the Brazilian rubber tree) is the only commercially available source of natural rubber (NR) for use in many products, which vary from tires to medical products such as adhesive bandages. H. brasiliensis NR is used in these products because after vulcanization, superior properties, which include elasticity,

Genomics of Rubber Biosynthesis in Hevea brasiliensis
2020The Hevea brasiliensis rubber tree is the largest commercial producer of natural rubber. The ability to synthesize a naturally occurring polymer is one of the main attractions of studying latex rubber biosynthesis. Natural rubber consists of high molecular weight cis-polyisoprene, a branch product of the isoprenoid network, which is synthesized by ...

Of the major biosynthetic pathways of the plant, that associated with the synthesis of rubber has been among the last to be elucidated. All that we know today concerning isoprenoid biogenesis is information acquired since 1949, much of it since 1956. Today, however, rubber biosynthesis may be considered as a problem solved.

A Mathematical Model of Rubber Biosynthesis
Computational Mathematics and Modeling, 2005A mathematical model is developed for the biosynthesis of rubber in plants. The model computes the steady-state concentrations of end products and intermediate metabolites that are present in the metabolic pathway of rubber biosynthesis. A number of different reactions occurring in the rubber-biosynthesis metabolic pathway are examined: an irreversible

The Plant Journal, 2015
SummaryTwo protein families required for rubber biosynthesis in Taraxacum brevicorniculatum have recently been characterized, namely the cis‐prenyltransferases (TbCPTs) and the small rubber particle proteins (TbSRPPs). The latter were shown to be the most abundant proteins on rubber particles, where rubber biosynthesis takes place. Here we identified a

Structure and Biosynthesis Mechanism of Rubber from Fungi
Rubber Chemistry and Technology, 1990Abstract The structure of both terminal units and alignment of the isoprene units give conclusive evidence for the initiation and termination mechanisms of rubber formation in fungi. As shown in Figure 4, the polymerization is estimated to start from trans, trans-farnesyl pyrophosphate and proceeds by successive condensation of IPP to form ...

Natural rubber biosynthesis in plants: rubber transferase.
Methods in enzymology, 2013Rubber biosynthesis in plants is a fascinating biochemical system, which evolved at the dawn of the dicotyledoneae and is present in at least four of the dictolydonous superorders. Rubber biosynthesis is catalyzed by a membrane complex in a monolayer membrane envelope, requires two distinct substrates and a divalent cation cofactor, and produces a high-

Initiator-independent and initiator-dependent rubber biosynthesis in Ficus elastica
Archives of Biochemistry and Biophysics, 2006The rubber-producing tree, Ficus elastica (the Indian rubber tree), requires the same substrates for rubber production as other rubber-producing plants, such as Hevea brasiliensis (the Brazilian or Para rubber tree), the major source of commercial natural rubber in the world, and Parthenium argentatum (guayule), a widely studied alternative for natural

Journal of Chromatography A, 2018
The natural rubber molecule is one of the end products of isoprenoids metabolism in the plant. Dimethylallyl diphosphate (DMAPP) and farnesyl pyrophosphate (FPP) are two typical isoprenoids which control the rate of biosynthesis and the molecular weight of natural rubber.
