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 ...

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.

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

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

Insights from natural rubber biosynthesis evolution for pathway engineering
Trends in Plant ScienceNatural 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.

Natural rubber, cis-1,4-polyisoprene, is a vital industrial material synthesized by plants via a side branch of the isoprenoid pathway by the enzyme rubber transferase. While the specific structure of this enzyme is not yet defined, based on activity it is probably a cis-prenyl transferase.

CHAPTER 2. Natural Rubber: Biosynthesis, Structure, Properties and Application
2013Rubber from Hevea brasiliensis, known as natural rubber (NR), contains rubber hydrocarbon and ca. 6% of non-rubber components. The biosynthesis of the NR latex particles takes place in the laticifers of the Hevea rubber tree. Rubber molecule is synthesized by the addition of isopentenyl diphosphate into farnesyl diphosphate, the initiating molecule ...

EuHDZ25 positively affects rubber biosynthesis by targeting EuFPS1 in Eucommia leaves
International Journal of Biological MacromoleculesEucommia ulmoides is a temperate gum source plant that produces trans-polyisoprene (TPI), also known as Eucommia rubber. The structural configuration and function of TPI offer a new material with important potential for industrial development. In this study, we detected the TPI content in the leaves of diploid and triploid E. ulmoides plants.
