Identification of some soluble esterases of the carrot (Daucus carota I.)

Creator:: Carino, Lourminia Almeda
Abstract:: Substrate and inhibitor specificities have been used to classify esterases. The purpose of this work was to determine the substrate and inhibitor specificities of the esterases in an aquous extract of lyophilyzed carrots. Esterase activity was determined manometrically at 37°C. The optimum pH of the carrot esterases with several substrates...

Identification of some esterases of the green bean (Phaseolus vulgaris L.)

Creator:: Putnam, Teryl Beebe
Abstract:: This investigation was conducted to differentiate the esterases in a water extract of freeze-dried green beans on the basis of inhibitor and substrate specificities. An attempt was made to classify these esterases according to the criteria used for animal esterases. Activity of the esterases was measured manometrically using the Gilson...

S-adenosylmethionine : [triangle]²⁴-sterol methyltransferase and the regulation of ergosterol biosynthesis in Saccharomyces cerevisiae

Creator:: Bailey, Richard B.
Abstract:: The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase (EC 2.1.1.41) activity by endogenous cellular components has been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺, NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition by potassium cation has been studied, and we have found that energy...

Biological oxidation of sorbitol

Creator:: Cummins, Joseph Thomas
Abstract:: The oxidation of sorbitol by soluble extracts of A. suboxydans proceeds by two pathways depending upon which pyridine nucleotide is present. In the presence of TPN, sorbose is formed. In the presence of DPN fructose is produced. Both products of the oxidation of sorbitol have been identified by paper chromatography,...

Effect of cadmium on ceruloplasmin levels in the rat

Creator:: Robinson, Alfred Vern
Abstract:: Injection of a 2.0 mg Cd ²⁺ /kg B.W. (I.P. as CdC1 ₂ in .05 M NaAc, pH = 6.9-7.2, .15 M or p = .15 with NaCl) resulted in a decrease in ceruloplasmin (EC 1.12.3) p-phenylenediamine oxidase activity within one hour of injection. Maximal decrease (40%) occurred within six...

Multiple forms of carboxylesterases in the green bean (Phaseolus vulgaris L.) and pea (Pisum sativum L.)

Creator:: Veerabhadrappa, Patnagere Siddaveera Sheety
Abstract:: Esterase activity of an aqueous extract of the green bean was separated into fourteen bands, while aqueous extracted pea esterases revealed seven bands, by polyacrylamide-gel electrophoresis. The fourteen bands of bean esterase activity formed three groups; slow, intermediate and fast moving. α-Naphthyl acetate, propionate, and n-butyrate and AS naphthol acetate...

The role of innate immunity in cnidarian-dinoflagellate symbiosis

Creator:: Poole, Angela Z.
Abstract:: Cnidarians, such as corals and sea anemones serve as hosts to a variety of organisms including symbiotic dinoflagellates, bacteria, virus, and apicomplexans. As corals are vital to the health and productivity of the reef ecosystem it is important to understand how these organisms interact with each component of the holobiont....

Urinary estrogens and progestins in pregnant pony mares

Creator:: Riad, Mohamed Tarek
Abstract:: Urinary steroids have been studied during early and late pregnancy in domestic horses or sporadic samples at various stages of pregnancy in wild equidae. In our studies, urinary estrone sulfate (E1S) and pregnanediol glucuronide (PdG) were monitored throughout pregnancy in six pony mares by enzyme immunoassay (EIA). Both hormones were...

Effect of berry integrity on proanthocyanidin extraction during wine production

Creator:: Cerpa-Calderon, Fiorella Karen
Abstract:: Proanthocyanidins are a grape-derived phenolic class of compound that provide wine with bitterness and astringency. Because of this, proanthocyanidins are considered to be essential components of wine quality. Proanthocyanidins are localized in the seed, skin and stem tissue of the grape berry and the composition of proanthocyanidins will vary depending...
