Micro method for determination of borohydride with NAD+
(Elsevier, 1973-08)
A spectrophotometric method for the determination of borohydride is described. It involves the reduction of NAD+ to a number of isomeric forms of NADH by borohydride. In the standard assay procedure herewith presented, ...
Soluble cytochrome b5 from human erythrocytes
(Elsevier, 1972-07-12)
1. A hemeprotein with properties similar to microsomal cytochrome b5 has been detected in the supernatant fraction of hemolysates of human, beef, and rabbit erythrocytes. A method has been developed for determining the ...
A game to help students comprehend enzyme structure and mechanism of action
(Elsevier, 1976-01)
Structural studies of capsular polysaccharide of type XII diplococcus pneumoniae
(Elsevier, 1974-10)
The capsular polysaccharide of Diplococcus pneumoniae Type XII contains residues of -glucose and -galactose in a molar ratio of 2:1. The methylated polysaccharide yielded upon hydrolysis 2,3,4,6-tetra- and 3,4,6-tri-O-me ...
Role of phospholipid in electron transfer in a reconstituted liver microsomal enzyme system containing cytochrome P-450
(Elsevier, 1971-08)
Phosphatidylcholine, which is required for fatty acid, hydrocarbon and drug hydroxylation in a reconstituted liver microsomal enzyme system, is essential for the enzymatic reduction of cytochrome P-450.
The inhibitive effects of steroid analogues in the binding of tritiated 5[alpha]-dihydrotecto3terone to receptor proteins from rat prostate tissue
(Elsevier, 1975-02)
The relationship between molecular structure and the binding potential of steroids to receptor proteins was investigated. Twenty-four selected steroids were studied in minced incubations of rat pro state tissue. Measurements ...
D-Glucuronic acid: A non-inhibitor of the concanavalin A system
(Elsevier, 1972-06-22)
D-Glucuronic acid is demonstrated not to inhibit the concanavalin A system; previous claims to the contrary are shown to be due to a pH effect. Concanavalin A does not precipitate biopolymers containing nonreducing, terminal ...
Tritium exchange reactions catalyzed by 2-oxo-4-hydroxyglutarate aldolase from Escherichia coli K-12
(Elsevier, 1979-05-10)
Tritiated water and tritiated substrates have been used to study exchange reactions catalyzed by Escherichia coli 2-oxo-4-hydroxyglutarate aldolase (4-hydroxy-2-oxoglutarate glyoxylate-lyase, EC 4.1.3.16, 2-oxo-4-hydroxyglutarate ...
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 ...
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. ...
