Activity and some properties of choline kinase, cholinephosphate cytidyltransferase and choline phosphotransferase during liver development in the rat
(Elsevier, 1973-10-17)
The activity of choline kinase (ATP:choline phosphotransferase, EC 2.7.1.32) cholinephosphate cytidyltransferase (CTP:cholinephosphate cytidyltransferase, EC 2.7.7.15) and cholinephosphotransferase (CDP-choline:1,2-diacy ...
Protein---carbohydrate interaction. : Part XXII. A chemically-synthesized d-mannan and the interaction of some synthetic d-mannans with concanavalin A
(Elsevier, 1970-06)
1,6-Anhydro-[beta]--mannopyranose was polymerized in the presence of chloroacetic acid. A high-molecular-weight fraction insoluble in 80% ethanol was isolated and studied. Periodate-oxidation studies showed the polymer to ...
The measurement of phosphatidate phosphohydrolase in human amniotic fluid
(Elsevier, 1978-03-30)
Phosphatidate phosphohydrolase (EC 3.1.3.4) activity can be found in late gestational human amniotic fluid and is thought to originate in type II alveolar cells of the fetal lungs where it plays an important role in lung ...
The solution behavior of the bovine myelin basic protein in the presence of anionic ligands binding behavior with the red component of trypan blue and sodium dodecyl sulfate
(Elsevier, 1976-04-14)
The interaction of the azo dye (2,3'-dimethyldiphenyl-7-azo-8-amino-l-napthol 3,6-disulfonic acid (TBR) and sodium dodecyl sulfate with the bovine myelin basic protein has been studied using absorbance, circular dichroism ...
Biosynthesis of keratan sulfate: Purification and properties of a galactosyltransferase from bovine cornea
(Elsevier, 1979-02)
A soluble galactosyltransferase was purified 22,000-fold from bovine cornea. The enzyme catalyzes the transfer of galactose from UDP-galactose to N-acetyl--glucosamine, [alpha]- and [beta]-glucosaminides, bovine cornea and ...
Effects of K+ on the catalytic and regulatory properties of homoserine dehydrogenase of Pseudomonas fluorescens
(Elsevier, 1971-04-14)
Partially purified homoserine dehydrogenase (-homoserine; NADP+ oxidoreductase, EC 1.1.1.3) isolated from Pseudomonas fluorescens requires K+ for its stability. At 1 mM K+, the apparent first-order rate constant for enzyme ...
Incorporation of ricinoleic acid into glycerolipids
(Elsevier, 1971-11-05)
The coenzyme A thiol ester of ricinoleic acid was synthesized and characterized. Ricinoleoyl-CoA has been tested as an acyl donor in several in vitro systems using rat liver microsomal acyltransferases.It is essentially ...
Studies in molecular structure, symmetry and conformation VI. Crystal and molecular structure of 1-aminocyclopentane carboxylic acid monohydrate
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Company Limited ; Springer Science+Business Media, 1972-07)
1-aminocyclopentane carboxylic acid monohydrate is monoclinic: space group P 2 1 / c , a = 11·24, b = 6·27, c = 11·22 Å and β = 97·6 °. The crystal structure was solved by the symbolic addition method and refined to an R ...
Crystal and molecular structure of 4-amino-4-carboxyl thiapyran hydrobromide
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-09)
4-Amino-4-carboxylthiapyran hydrobromide crystallizes in the monoclinic space group P 2 1 / m , with a = 9.72 Å, b = 6.60 Å and c =7.10 Å,β = 94.8 ° and Z = 2. The structure was solved by the heavy atom method with 786 ...
