An "extension" of the carbohydrate binding specificity of concanavalin A
(Elsevier, 1973-08-30)
Evidence based on the quantitative precipitin method and hapten inhibition technique demonstrates that concanavalin A may interact with internal 2-O-linked [alpha]--mannopyranosyl residues as may occur in glycoproteins and ...
Trimethylstannyl-2,4-cycloheptadiene: A fluxional molecule
(Elsevier, 1972-05-16)
Trimethylstannyl-2,4-cycloheptadiene (II) was synthesized and shown to be fluxional on the NMR time scale. The activation energy for the [1,5] trimethyltin migration is estimated to be ca. 18 kcal/mole. This value is ...
The control of fatty acid composition in glycerolipids of the endoplasmic reticulum
(Elsevier, 1970-02-03)
A functional relationship between constitutive enzymes of the endoplasmic reticulum that are involved in lipid metabolism and the proteins and phosphoglycerides constituting these membranes was examined by altering the ...
Thermodynamics of Fe(II)Fe(III) oxide systems II. Zinc- and cadmium-doped Fe3O4 and crystalline magnetite
(Elsevier, 1976-06)
Four doped samples of composition MzFe3 - xO4, in which for M = cadmium, x = 0.005 and 0.010, and for M = zinc, x = 0.005 and 0.066, were prepared using a high-temperature solid-state ceramic technique. X-ray, magneto-t.g.a., ...
Evidence for a novel flavin prosthetic group associated with NADH dehydrogenase from Peptostreptococcus elsdenii
(Elsevier, 1971-05-12)
1. 1. NADH dehydrogenase (EC 1.6.99.3) has been purified from the strictly anaerobic rumen bacterium Peptostreptococcus elsdenii. The purified protein is specific for NADH as electron donor; it can use 2,6-dichlorophenolindophenol ...
Electrophilic alkylation of 1-SB9H9
(Elsevier, 1977-06-21)
Reaction of closo-1-SB9H9 with either ethyl or methyl iodide in the presence of A1C13 produces alkylated derivatives of the type 1-SB9H(9-x)Rx (R = C2H5, CH3;x = 1---5), which were identified by GC/MS, 11B and 1H NMR ...
The purification and properties of an alcohol dehydrogenase from mouse liver
(Elsevier, 1974-04)
1. 1. An alcohol dehydrogenase (alcohol: NAD oxidoreductase, EC ( [middle dot] [middle dot] ) was isolated from the supernatant fraction of mouse liver and purified 206-fold.2. 2. A number of aliphatic aldehydes, ranging ...
Destruction and resynthesis of mouse [beta]-glucosidases
(Elsevier, 1979-02-01)
1. 1. Injection of a single dose of conduritol B epoxide into mice produced almost complete destruction of glucocerebrosidase ( glucohydrolase, EC 3.2.1.45) in liver, spleen, brain, and kidney within 5 h. Restoration of ...
Soluble cytochrome b5 reductase from human erythrocytes
(Elsevier, 1972-07-12)
1. An enzyme that catalyzes the reduction of erythrocyte cytochrome b5 has been isolated from the supernatant fraction of erythrocyte hemolysates by chromatography on DEAE-cellulose, Amberlite CG-50, and Bio-Gel P-60.2. ...
