Crystal and molecular structure of 4-amino-4-carboxyl thiapyran
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-11)
4-Amino-4-carboxylthiapyran crystallizes in space group P 2 1 / c with a = 10.61, b = 6.55, c = 10.97 Å, β =96.3 °, and Z = 4. The structure was solved by the heavy-atom method, with 897 observed reflections, and refined ...
Solution properties and structure of brain proteolipids
(Wiley Subscription Services, Inc., A Wiley Company, 1968-07)
Bovine white matter proteolipids have been studied by several physical methods and have been found to exist as micelles in 2 : 1 (v/v) chloroform–methanol solution. The data would indicate the existence of a critical micelle ...
Preparation of 32P-labeled inositides and their degradation by soluble kidney enzymes
(Elsevier, 1975-07-22)
A method is described for the preparation of radioactive inositol lipids for studies of their enzymic degradation. Kidney cytosol fractions have been used to produce diesteratic cleavage. High voltage electrophoresis at ...
Non-specific protein binding by adsorbents designed for the specific affinity chromatography of sialidase in crude bacterial extracts
(Elsevier, 1974-12-18)
A number of derivatives of Sepharose 4B gels were prepared containing tyramine, -Gly-Gly-Tyr and the tetrapeptide, Thr (But)-Phe-Pro-Tyr-. A specific inhibitor of sialidase, p-diazo-phenyl oxamic acid, was also coupled to ...
Interaction of pneumococcal S-14 polysaccharide with lectins from Ricinus communis, Triticum vulgaris, and bandeiraea simplicifolia
(Elsevier, 1977-09)
Two purified lectins, namely, wheat-germ agglutinin (from Triticum vulgaris) and the hemagglutinin from Ricinus communis seeds, readily form a precipitate with pneumococcal S-14 polysaccharide, whereas the Bandeiraea ...
Dependence of an alkyl glycol-ether monooxygenase activity upon tetrahydropterins
(Elsevier, 1990-08-01)
Glyceryl-ether monooxygenase (1-alkyl-sn-glycerol,tetrahydropteridine:oxygen oxidoreductase, EC 1.14.16.5) catalyzes the oxidative cleavage of 1-O-alkyl glycerol or glycol derivatives to a long-chain aldehyde and the ...
Stereospecific synthesis and enzyme studies of CDP-diacylglycerols
(Elsevier, 1982-09-14)
The fatty acid specificity of two enzymes that metabolize CDPdiacylglycerol, CDPdiacylglycerol hydrolase (EC 3.6.1.26) and CDPdiacylglycerol:inositol phosphatidyltransferase (EC 2.7.8.11), has been examined in guinea pig ...
Activation of CTP : Phosphocholine cytidylyltransferase in rat lung by fatty acids
(Elsevier, 1981-07-24)
CTP : phosphocholine cytidylyltransferase activity exists in both the microsome and cytosol fractions of adult lung, 36 and 59%, respectively. Although these enzyme activities are stimulated in vitro by added lipid activators ...
Estimation of acyldihydroxyacetone phosphate and lysophosphatidate in animal tissues
(Elsevier, 1984-11-14)
Chemical and enzymatic methods have been developed to measure small quantities (10-8-10-10 mol) of acyldihydroxyacetone phosphate in animal tissues. Lipids extracted from tissue samples with acidic CHCl3/ methanol were ...
Protein-carbohydrate interaction , : VI. Isolation of concanavalin a by specific adsorption on cross-linked dextran gels
(Elsevier, 1967-10-23)
1. 1.|A new method is described for the isolation and purification of concanavalin A based on its specific adsorption on cross-linked dextran gels and subsequent displacement with -glucose.2. 2.|The yield of concanavalin ...
