Studies on hydroperoxide-dependent substrate hydroxylation by purified liver microsomal cytochrome P-450
(Elsevier, 1976-08)
Highly purified liver microsomal cytochrome P-450 catalyzes the hydroperoxide-dependent hydroxylation of a variety of substrates in the absence of NADPH, NADPH-cytochrome P-450 reductase, and molecular oxygen. The addition ...
Characterization of the [omega]-hydroxylase of Pseudomonas oleovorans as a nonheme iron protein
(Elsevier, 1977-10)
The [omega]-hydroxylase of Pseudomonas oleovorans, which catalyzes the hydroxylation of fatty acids and alkanes and the epoxidation of alkenes in the presence of a reduced pyridine nucleotide, a reductase, rubredoxin, and ...
Ethanolamine phosphokinase: Activity and properties during liver development
(Elsevier, 1972-07-13)
The conditions for maximal activity of ethanolamine phosphokinase from rat liver were determined. All of the activity was located in the supernatant fraction after centrifugation at 100 000 x g for 60 min. The enzyme ...
Sulfhydryl groups in relation to the structure and catalytic activity of 2-OXO-4-hydroxyglutarate aldolase from bovine liver
(Elsevier, 1977-03-15)
Bovine liver 2-oxo-4-hydroxyglutarate aldolase (suggested name: 2-oxo-4hydroxyglutarate glyoxylate-lyase catalyzing the reaction: 2-oxo-4-hydroxyglutarate rlhar2 pyruvate + glyoxylate) contains eight to ten sulfhydryl ...
A sensitive fluorescent method for the detection of glycoproteins in polyacrylamide gels
(Elsevier, 1976-05-21)
A sensitive method is described for the detection of glycoproteins after polyacrylamide gel electrophoresis. Dansyl hydrazine is condensed with aldehydic functions generated by periodate oxidation of protein bound carbohydrate. ...
Studies in molecular structure, symmetry and conformation
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Company Limited ; Springer Science+Business Media, 1971-06)
1-aminocyclohexane carboxylic acid hydrochloride crystallizes in the monoclinic space group P 2 1 with unit cell dimensions a = 9·36, b = 6·40, c = 7·40 Å and β = 96·0 °. The structure has been solved by beta synthesis and ...
The relative utilization of the acyl dihydroxyacetone phosphate and glycerol phosphate pathways for synthesis of glycerolipids in various tumors and normal tissues
(Elsevier, 1975-03-24)
Rates of phosphatidate synthesis from dihydroxyacetone phosphate via acyl dihydroxyacetone phosphate or glycerol phosphate are compared in homogenates of 13 tissues, most of which are deficient in glycerol phosphate ...
Gas-liquid chromatography of carbohydrate derivatives: the separation and quantitative determination of synthetic and naturally occurring glycosyl derivatives of amino acids
(Elsevier, 1972-05)
A gas-liquid chromatographic separation of the trimethylsilyl derivatives of several synthetic and naturally occurring glycosyl derivatives of amino acids is described. This technique may be used for the qualitative and ...
Radioiodination of sulfhydryl-sensitive proteins
(Elsevier, 1975-08)
A new procedure is described for the radioiodination of proteins with sulfhydryl groups essential for their biological activity. Aniline is iodinated with 125I-labeled sodium iodide in the presence of chloramine-T, the ...
