Natural rubber biosynthesis—A living carbocationic polymerization?

Progress in Polymer Science, 2006
Abstracts An exhaustive in-depth review of the biochemical literature concerning the biosynthesis of polyisoprenes, including natural rubber (NR, cis -1,4-polyisoprene c PIP) by rubber-producing plants, and the polymer chemical literature on biomimetic and related syntheses, leads us to postulate that the biosynthesis of polyisoprenoids in general ...

Latex-specific transcriptome analysis reveals mechanisms for latex metabolism and natural rubber biosynthesis in laticifers of Hevea brasiliensis

Industrial Crops and Products, 2021
Abstract Natural rubber, produced in the laticifers of the para rubber tree (Hevea brasiliensis), is a valuable biopolymer of commercial and strategic importance. While the basic pathway of rubber biosynthesis has been established, further understanding of its regulatory mechanisms might be obtained by studying laticifer-specific gene expression ...

Subcellular proteome profiles of different latex fractions revealed washed solutions from rubber particles contain crucial enzymes for natural rubber biosynthesis

Journal of Proteomics, 2018
Rubber particle (RP) is a specific organelle for natural rubber biosynthesis (NRB) and storage in rubber tree Hevea brasiliensis. NRB is processed by RP membrane-localized proteins, which were traditionally purified by repeated washing. However, we noticed many proteins in the discarded washing solutions (WS) from RP.

Comparative full-length transcriptome analysis provides novel insights into the regulatory mechanism of natural rubber biosynthesis in Taraxacum kok-saghyz Rodin roots

Industrial Crops and Products, 2021
Abstract Taraxacum kok-saghyz Rodin (TKS) is a promising alternative rubber-producing plant due to the high-quality natural rubber (NR) synthesized in its root. Nevertheless, the comprehensive molecular mechanisms of NR biosynthesis in TKS roots remains segmented and elusive. In the current study, to elucidate the regulatory mechanism of NR synthesis

Insights from natural rubber biosynthesis evolution for pathway engineering

Trends in Plant Science
Natural rubber (NR), valued for its elasticity and impact resistance, is essential for numerous industrial and medical applications, with global demand continuously rising. While approximately 2500 plant species from more than 40 families can produce rubber, the majority is sourced from Hevea brasiliensis grown in tropical regions.

Unusual subunits are directly involved in binding substrates for natural rubber biosynthesis in multiple plant species

Phytochemistry, 2018
Rubber particles from rubber-producing plant species have many different species-specific proteins bound to their external monolayer biomembranes. To date, identification of those proteins directly involved in enzymatic catalysis of rubber polymerization has not been fully accomplished using solubilization, purification or reconstitution approaches. In

Silencing the lettuce homologs of small rubber particle protein does not influence natural rubber biosynthesis in lettuce (Lactuca sativa)

Phytochemistry, 2014
Natural rubber, cis-1,4-polyisoprene, is an important raw material in chemical industries, but its biosynthetic mechanism remains elusive. Natural rubber is known to be synthesized in rubber particles suspended in laticifer cells in the Brazilian rubber tree (Hevea brasiliensis). In the rubber tree, rubber elongation factor (REF) and its homolog, small

UNRAVELING THE MYSTERY OF NATURAL RUBBER BIOSYNTHESIS. PART II: COMPOSITION AND GROWTH OF IN VITRO NATURAL RUBBER USING HIGH-RESOLUTION SIZE EXCLUSION CHROMATOGRAPHY

Rubber Chemistry and Technology, 2014
ABSTRACT The superior properties of natural rubber (cis-1,4-polyisoprene [NR]) are a function of its structure and composition, properties that still remain a mystery and that are irreplaceable by any synthetic rubber. NR from guayule (Parthenium argentatum) has been gaining special interest for its hypoallergenic properties while maintaining ...

Natural rubber biosynthesis in plants: rubber transferase.

Methods in enzymology, 2013
Rubber 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-

CRISPR-Cas9 enabled molecular genetic studies of natural rubber biosynthesis in lettuce

2022
Natural rubber (NR) is an industrially essential biopolymer due to its irreplicable properties. To date the only necessary components identified for NR biosynthesis are two membrane-bound proteins, cis-prenyltransferase (CPT) and CPT binding protein (CBP) that form a complex in which CPT catalyzes the addition of isopentyl pyrophosphate (IPP) subunits ...
