beta amylase/zea mays

In the present work, alpha- and beta-amylase enzymes from Zea mays malt were recovered by continuous extraction in a PEG/CaCl2 aqueous two-phase system (ATPS). The influences of the flux rate (RQ), free area of vane (A(free)) and vane rotation (RV) on enzyme recovery were studied by optimization

The present study investigated the impact of 1800-MHz electromagnetic field radiations (EMF-r), widely used in mobile communication, on the growth and activity of starch-, sucrose-, and phosphate-hydrolyzing enzymes in Zea mays seedlings. We exposed Z. mays to modulated continuous wave homogenous

beta-Amylase of maize (Zea mays L.) caryopses was studied during development and germination by means of enzymic, electrophoretic, and immunochemical techniques. beta-Amylase activity increased during caryopsis development to a maximum value at the beginning of the water content plateau (at this

A maize (Zea mays L.) cDNA clone (pZMB2) encoding beta-amylase was isolated from a cDNA library prepared from the aleurone RNA of germinating kernels. The cDNA encodes a predicted product of 488 amino acids with significant similarity to known beta-amylases from barley (Hordeum vulgare), rye (Secale

The etched (et) mutation in maize causes distinct depressions and structural gaps in the endosperm and also gives rise to virescent seedlings, α- and β-Amylase activities were observed to be higher in et (+) et (+) kernels and seedlings as compared to that of the et et mutant. The total amylase and

The presence of phospholipids reduces the breakdown of amylose catalyzed by β-amylase, phosphorylase and α-amylase. The activities of the β-amylases of sweet potato (Ipomoea batatas) and barley (Hordeum vulgare L.) disminish to less than 10% of the activity in the control without the phospholipids.
