Chemical modification studies on Ricinus communis (Castor Bean) agglutinin.
Ricinus communis agglutinin was subjected to various chemical treatments and the effect on its hemagglutinating and saccharide-binding properties was studied. Acetylation, succinylation and citraconylation led to a complete loss in the activity of the agglutinin, whereas reductive methylation had no effect on the activity, showing that charged amino groups were involved in the hemagglutinating ...
متن کاملChemical Investigations of the Castor Bean Plant Ricinus communis
In 2009 a National Security Science and Technology grant was awarded to the Human Protection and Performance Division for the investigation of several forensic aspects of the castor bean plant Ricinus communis. A major focus of this grant was to understand the chemical composition of the seeds, and to ascertain if these differences could be used for provenance classification. This technical rep...
متن کاملThe surface glycoproteins of human skin fibroblasts detected after electrophoresis by the binding of peanut (Arachis hypogaea) agglutinin and Ricinus communis (castor-bean) agglutinin I.
A new methodology was developed to study the cell-surface glycoproteins of cultured human skin fibroblasts. This was based on the binding of a variety of biotinyl-lectins to nitrocellulose electrophoretic transfers of total fibroblast lysates after separation in sodium dodecyl sulphate/polyacrylamide gels, followed by reaction with avidin-biotinyl-peroxidase complexes and detection with 3,3'-di...
متن کاملFunctional characterization of castor bean (Ricinus communis) DGAT3 and DAcT enzymes in Arabidopsis thaliana
Background Triacylglycerols (TAGs) are the main seed storage lipids of plants. TAGs chemichal properties are largely dependent on their fatty acid composition. Diacylglycerol Acyltransferase (DGAT) genes encode the main enzymes needed for TAG biosynthesis. Different types of DGAT genes (named DGAT1, DGAT2, DGAT3 and DAcT) have been identified in plants. DGAT1 and DGAT2 are well characterized, b...
متن کاملDifferential Expression Patterns of Lipid Genes in Developing Seeds of Castor Bean (ricinus Communis L.)
Castor bean (Ricinus communis L.) is one of the most important non-edible oilseed crops. Characterization of seed development and lipid accumulation from female flowers pollinated to mature seeds has been carried out. The temporal expression patterns of 65 lipid genes involved in fatty acid and triacylglycerol biosynthesis using the semi-quantitative RT-PCR technique were also investigated. The...
