Acetolactate and Acetoin Synthesis in Ripening Peas.
The role of acetolactate as a precursor in valine biosynthesis was first indicated by the isotopic studies of Strassman et al. (18) and was subsequently supported by work on valine-less mutants of Escherichia coli (21,22) and Neurospora crassa (24). The direct conversion of acetolactate to a number of valine precursors, and to valine itself, has since been demonstrated in cell-free extracts of ...
متن کاملIsolation of glutamine synthetase and glutamotransferase from green peas.
The enzyme system catalyzing this has been termed “glutamine synthetase” and for convenience this name will be used here. Ammonia in this reaction can be replaced by hydrasine or hydroxylamine, all three bases reacting at the same rate (4). All organic bases and amino acids tested have been found to be inactive. With hydroxylamine, a hydroxamic acid is produced, estimation of which provides a c...
متن کاملEnzymatic synthesis of oligosaccharides
The biological interest of oligosaccharides is growing very rapidly, and necessitates the development of efficient synthesis reactions. The stereoand regio-selectivity of enzyme catalysis is a key advantage in this field, as a complementary tool to the chemical approach. Two types of enzymes can be applied to the obtention of oligosaccharides: Hydrolytic enzymes, which can catalyze either rever...
متن کاملMicrowave Drying Characteristics of Green Peas and its Quality Evaluation
The drying characteristics of green peas were examined in a microwave dryer for power level of 20,40 and 60W. The green peas were pretreated with citric acid solutions and blanched with hot water at 85C before drying. The drying process was continued until sample moisture fell to equilibrium moisture content. The blanched samples dried faster than those in other pretreatments and control condit...
متن کاملEnzymatic synthesis of oligosaccharides from maltose by germinated green gram (Phaseolus radiatus).
A rat liver enzyme, capable of synthesizing linear dextrins from maltose, was discovered in this laboratory (1). Later, a similar enzyme was identified and highly purified from bovine plasma by Miller and Copeland (2, 3). The mechanism of rat liver transglycosylase has recently been studied by Stetten (4). Transferases which are capable of oligosaccharide synthesis from disaccharides have been ...
