A Stimulator Protein of Rubber Biosynthesis from Hevea brasiliensis Latex
A rubber biosynthesis stimulator protein (RBSP)from the C-serum of Hevea brasiliensis latex was purified and characterised. This proteinaceous factor stimulates the incorporation of isopentenyl diphosphate into rubber and thereby enhances the rate of rubber biosynthesis. The heat stable RBSP is shown to have a molecular weight of 13 068 Da by mass spectroscopy. Amino acid sequence of peptide fr...
متن کاملMetabolic routes affecting rubber biosynthesis in Hevea brasiliensis latex
The cytosolic mevalonate (MVA) pathway in Hevea brasiliensis latex is the conventionally accepted pathway which provides isopentenyl diphosphate (IPP) for cis-polyisoprene (rubber) biosynthesis. However, the plastidic 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway may be an alternative source of IPP since its more recent discovery in plants. Quantitative RT-PCR (qRT-PCR) expression profiles ...
متن کاملInsights into rubber biosynthesis from transcriptome analysis of Hevea brasiliensis latex.
Hevea brasiliensis is the most widely cultivated species for commercial production of natural rubber (cis-polyisoprene). In this study, 10,040 expressed sequence tags (ESTs) were generated from the latex of the rubber tree, which represents the cytoplasmic content of a single cell type, in order to analyse the latex transcription profile with emphasis on rubber biosynthesis-related genes. A tot...
متن کاملCDNA library from the latex of Hevea brasiliensis
Latex from Hevea brasiliensis contains 30-50% (w/w) of natural rubber (cis-1,4-polyisoprene), the important raw material for many rubber industries. We have constructed a cDNA library from the latex of H. brasiliensis to investigate the expressed genes and molecular events in the latex. We analyzed 412 expressed sequence tags (ESTs). More than 90% of the EST clones showed homology to previously...
متن کاملAllergenic Proteins of Hevea brasiliensis Latex Fractions
A spectrum of proteins derived from the rubber tree, Hevea brasiliensis, reacted with IgE in the plasma from persons allergic to natural rubber latex. Latex B-serum, C-serum and rubber particle membrane proteins were all found to contain allergenie proteins. Variations were observed in the reactivity of the latex, IgE positive plasma to the different proteins. Monoclonal antibodies have been de...
