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 ...
Hydrocarbon oxidation by a bacterial enzyme system : I. Products of octane oxidation
(Elsevier, 1963)
A Pseudomonad which grows on hexane as sole carbon source was isolated from soil by enrichment-culture technique. Cell-free, soluble enzyme preparations of the organism catalyze the oxidation of 14C-labeled octane to ...
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 ...
Ethanolaminephosphotransferase in rat lung: selectivity for endogenous and exogenous diacylglycerol
(Elsevier, 1988-05-02)
Ethanolaminephosphotransferase (EC 2.7.8.1) activity was determined in lung microsomes using diacylglycerols generated endogenously from [14C]glycerol 3-phosphate and different mixtures of fatty acids Ethanolaminephospho ...
The sulfhydryl content of -threonine dehydrogenase from Escherichia coli K-12: relation to catalytic activity and Mn2+ activation
(Elsevier, 1990-01-19)
When oxidized to cysteic acid by performic acid or converted to carboxymethylcysteine by alkylation of the reduced enzyme with iodoacetate, a total of six half-cystine residues/subunit are found in -threonine dehydrogenase ...
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 ...
Renaturation of glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides after denaturation in 4 M guanidine hydrochloride: kinetics of aggregation and reactivation
(Elsevier, 1993-04-21)
In 4 M guanidine hydrochloride (GdnHCl), the dimeric enzyme glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides (G6PD) dissociated to subunits and was extensively unfolded. Rapid dilution of this high GdnHCl ...
