Wheat (Triticum aestivum) RNA was used to program synthesis of the alpha-amylase protein by Xenopus laevis oocytes. A 41,500-dalton protein was made which was identified as alpha-amylase by immunoprecipitation with rabbit anti-alpha-amylase antiserum raised against the purified wheat protein and by its co-migration with authentic alpha-amylase on sodium dodecyl sulfate polyacrylamide gels. Synt...

Four hundred and forty 1-day-old Arbor Acre broilers were fed commercial starter diets with 0, 250, 750 and 2,250 mg/kg of an alpha-amylase preparation from 1 to 21 days of age to investigate the effects of an exogenous enzyme on growth performance, activities of digestive enzymes in the pancreas and anterior intestinal contents and pancreatic amylase mRNA expression. Body weight gain (BWG) and...

Several investigated bank vole populations are polymorphis for the number of salivary amylase loci, and individual chromosomes may carry one, two or three linked amylase structural genes. In the present study, we have used bank vole stocks homozygous for different chromosomes to investigate the relationship between amylase production and gene number. By measuring the amylase activity in parotid...

The enzymatic activity of salivary amylase bound to the surface of several species of oral streptococci was determined by the production of acid from starch and by the degradation of maltotetraose to glucose in a coupled, spectrophotometric assay. Most strains able to bind amylase exhibited functional enzyme on their surface and produced acid from the products of amylolytic degradation. These s...

Abstract Violations of no-arbitrage conditions measure the shadow cost intermediary constraints. Intermediary asset pricing and intertemporal hedging together imply that risk these constraints tightening is priced. We describe a “forward CIP trading strategy” bets on violations shrinking show its returns help identify price this risk. This strategy yields highest for currency pairs associated w...

Alpha-amylase was immobilized onto polyaniline-polyvinyl alcohol (PAni-PVA) film by cross linking with glutaraldehyde. The activity yield and immobilization efficiency was calculated as 13.58% and 30.60% respectively. The PAni-PVA-Amylase films were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and amylase activity assay. The immobilized α-amylase had its optimum activity at p...

We study incentive provision in a model of securities issuance with an informed issuer and uninformed investors. We show that the presence of an informed intermediary may increase surplus even if we allow for collusion between the intermediary and the issuer. Collusion is neutralized by introducing a misalignment between the interests of the issuer and those of the intermediary. To achieve this...

The gene for beta-amylase was isolated from Bacillus polymyxa by molecular cloning in B. subtilis. B. subtilis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydrolysis with this beta-amylase produces maltose, not glucose, whereas maltotrio...
