Amylases from aleurone layers and starchy endosperm of barley seeds.
Amylases from incubated aleurone layers or from starchy endosperm of barley seeds (Hordeum vulgare L. cv. Himalaya) were investigated using acrylamide gel electrophoresis and analytical gel filtration with Sephadex G-200. Electrophoresis of amylase from aleurone layers yields seven visually distinct isozymes with an estimated molecular weight of 43,000. Because each isozyme hydrolyzes beta-limi...
متن کاملCharacteristics of two forms of alpha-amylases and structural implication.
Complete (Ba-L) and truncated (Ba-S) forms of alpha-amylases from Bacillus subtilis X-23 were purified, and the amino- and carboxyl-terminal amino acid sequences of Ba-L and Ba-S were determined. The amino acid sequence deduced from the nucleotide sequence of the alpha-amylase gene indicated that Ba-S was produced from Ba-L by truncation of the 186 amino acid residues at the carboxyl-terminal r...
متن کاملα′ Subunit of soybean β-conglycinin forms complex with rice glutelin via a disulphide bond in transgenic rice seeds*
The alpha' and beta subunits of soybean beta-conglycinin were expressed in rice seeds in order to improve the nutritional and physiological properties of rice as a food. The alpha' subunit accumulated in rice seeds at a higher level than the beta subunit, but no detectable difference in mRNA transcription level between subunits was observed. Sequential extraction results indicate that the alpha...
متن کاملMultiple forms of membrane-bound beta-glucosidase in human leucocytes.
insulin has been suggested by Cuatrecasas & Illiano (197 1) on the basis of neuraminidase treatment of adipose-tissue cells. Enzymic digestion was reported to have no effect on the total quantity of insulin receptor in the membranes or on the affinity of the receptor for insulin, but abolished the effect of insulin on glucose transport and on lipolysis. As shown in Fig. 1, neuraminidase action ...
متن کاملEnzymic Mechanism of Starch Breakdown in Germinating Rice Seeds: 8. Immunohistochemical Localization of beta-Amylase.
Rabbit antiserum against beta-amylase isolated from germinating seeds of rice was produced, and its specific cross-reactivity with beta-amylase was confirmed by means of Ouchterlony double immunodiffusion and immunoelectrophoresis procedures. The cellular localization of beta-amylase was studied by indirect fluorescence microscopy of thin sectioned germinating rice seed specimens (1-day stage) ...
