Beta-amylase degradation by serine endoproteinases from green barley malt
Proteolytic degradation of barley proteins is examined in green (unkilned) malt and germinating seeds from Hordeum vulgare L. cv. Harrington. Zymographic analysis of the Harrington green malt extracts using commercial preparations of barley beta-amylase incorporated as a proteolytic substrate in 2-D SDS gels shows multiple proteolytic activities. A developmental study shows that the several gre...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولIMMUNOHISTOCHEMTCAL LOCALIZATION OF a-AMYLASE IN BARLEY ALEURONE CELLS
a-Amylase was localized in aleurone cells of barley using immunohistochemical methods. Anti-a-amylase antibody was produced by rabbits immunized with enzyme purified from malt diastase and Himalaya variety barley seeds. Immunoelectrophoresis showed that the antibodies to both antigens were immunologically similar, therefore, they were used interchangeably in the localization of a-amylase. Fluor...
متن کاملGibberellic acid-controlled synthesis of alpha-amylase in barley endosperm.
Because the endosperm half of a barley seed produces several hydrolytic enzymes in response to added gibberellins (1, 4, 5, 8), it is an attractive experimental system for a study of the mechanism of action of gibberellic acid. The only living cells in the half seed are those of the aleurone layers. These are an apparently homogeneous collection of respiring, nondividing cells which have the hi...
متن کاملalpha-Amylase Isozymes in Gibberellic Acid-treated Barley Half-seeds.
The presence of multiple forms of alpha-amylase in gibberellic acid-treated embryoless barley half-seeds was demonstrated by separation on diethylaminoethyl-Sephadex and isoelectric focusing polyacrylamide gel disc electrophoresis. Two major alpha-amylase fractions (A and B), each consisting of two to three isozyme components, were purified. alpha-Amylase fractions A and B were distinguishable ...
