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. ...
2-acetamido-2-deoxy-[alpha]-D-galactosidases of clostridium perfringens. separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]-D-galactosidases have been separated from filtrates of cultured Clostridium perfringens by electrophoresis in 6.5% poly(acryl-amide) gels. One of the enzymes had a mobility of ...
2-acetamido-2-deoxy-[alpha]--galactosidases of clostridium perfringens. Separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]--galactosidases have been separated from filtrates of cultured Clostridium perfringens by electrophoresis in 6.5 % poly(acryl-amide)gels. One of the enzymes had a mobility of 0.32-0.36 ...
Formation of Dg-1-amino-2-propanol by a highly purified enzyme from Escherichia coli
(Elsevier, 1968-05-14)
Increased synthesis of phosphatidylcholine by rat lung following premature birth
(Elsevier, 1980-01-18)
Pregnant rats were delivered prematurely at 20 days and 21 days gestation (2 and 1 day premature). The survival was 52 +/- 3% at 20 days gestation and 100% at 21 days gestation. [Me-14C]Choline incorporation into ...
Purification and properties of S-protein (hemoprotein 559) from human erythrocytes
(Elsevier, 1971-01-19)
1. 1. A procedure employing mild conditions has been developed for purifying S-protein (hemoprotein 559, erythrocyte), a protein present in the stromal fraction of human red blood cells. S-protein, solubilized by extracting ...
Simple, rapid, and highly efficient separation of amino acid phenylthiohydantoins by reversed-phase high-performance liquid chromatography
(Elsevier, 1982-04)
A rapid and efficient separation of amino acid phenylthiohydantoins by high-performance liquid chromatography has been accomplished by step-gradient elution with use of a mobile phase of acetate-buffered aqueous acetonitrile ...
Variant properties of bovine liver 2-keto-4-hydroxyglutarate aldolase; its [beta]-decarboxylase activity, lack of substrate stereospecificity, and structural requirements for binding substrate analogs
(Elsevier, 1971-10-20)
1. 1. 2-Keto-4-hydroxyglutarate aldolase (2-oxo-4-hydroxyglutarate glyoxylatelyase; reaction: 2-oxo-4-hydroxyglutarate [left harpoon over right] pyruvate + glyoxylate) catalyzes the cleavage and the formation of both optical ...
Phosphatidate phosphatase : Activity and properties in fetal and adult rat lung
(Elsevier, 1978-09-28)
The purpose of this work is to compare the properties of phosphatidate phosphatase (-[alpha]-phosphatidate phosphohydrolase, EC 3.1.3.4) in fetal and adult rat lung and to establish the developmental profile of activity ...
Solution behavior, circular dichroism and 220 MHz PMR studies of the bovine myelin basic protein
(Elsevier, 1975-09-09)
Bovine myelin basic protein has been investigated with regard to its solution behavior, circular dichroism and 220 MHz PMR spectral properties.At pH 4.8 [gamma]/2 = 0.1 acetate buffer, light scattering yielded a Mr of 17 ...
