D-hydantoinase from Vigna angularis was immobilized by covalent linkage to aminopropyl glass beads. Thermal stability, resistance to storage at different pH values and temperatures of this biocatalyst were studied. This enzyme preparation was used as a catalyst to prepare enantioenriched N-carbamoyl-D-phenylglycine, N-carbamyl-D-p-fluorophenylglycine and(More)
D-Hydantoinase from Vigna angularis hydrolyzed rac-5-monosubstituted-hydantoins with polar and aromatic side chains and dihydrothymine but rac-5,5-disubstituted-hydantoins were not substrates of this enzyme. 5-Phenylhydantoin was the best substrate. By using this substrate, Ncarbamoyl-D-phenylglycine was obtained in quantitative yield and over 98% ee.
Seven professional usability labs and one university student team have carried out independent, parallel usability tests of the same state-of-the-art, live, commercial web site. The web site used for the usability tests is, a major provider of free web-based e-mail. The panel will discuss similarities and differences in process, results and(More)
