Allergenic 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...
متن کاملGlycolipid composition of Hevea brasiliensis latex.
Glycolipids of fresh latex from three clones of Hevea brasiliensis were characterized and quantified by HPLC/ESI-MS. Their fatty acyl and sterol components were further confirmed by GC/MS after saponification. The four detected glycolipid classes were steryl glucosides (SG), esterified steryl glucosides (ESG), monogalactosyl diacylglycerols (MGDG) and digalactosyl diacylglycerols (DGDG). Sterol...
متن کاملGenes expressed in the latex of Hevea brasiliensis.
Rubber (cis-1,4-polyisoprene), an important raw material for many industrial uses, is synthesized in the latex of Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg. We postulated that the genes uniquely or preferentially expressed in the latex may be important for rubber biosynthesis. We constructed cDNA libraries from the latex of H. brasiliensis to investigate the genes expressed in the latex...
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 کاملA 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...
