Competitive stimulation: Further evidence for two carriers in the transport of neutral amino acids
(Elsevier, 1967-09-09)
1. 1. Two explanations have been proposed for the stimulation of uptake of one amino acid in the presence of another, a phenomenon which has been demonstrated for some pairs of amino acids in uptake studies with ascites ...
Protein-carbohydrate interaction XX. On the number of combining sites of concanavalin A, the phytohemagglutinin of the jack bean
(Elsevier, 1968-10-15)
Equilibrium dialysis of concanavalin A against methyl [alpha]--mannopyranoside and methyl [alpha]--glucopyranoside conducted at 2[deg] in the presence of 1 M NaCl showed that concanavalin A is bivalent. plot of the data ...
Electron paramagnetic resonance studies on the cytochrome oxidase from yeast

Nature of the anodic tellurate wave at the dropping mercury electrode
(Elsevier, 1962-04)
Tellurate solutions at the dropping mercury electrode show an adsorption type anodic wave in the vicinity of zero volts vs. S.C.E. The presence of this anodic wave is attributed to depolarization of mercury electrode and ...
Electrochemical oxidation-reduction paths for pyrimidine, cytosine, purine and adenine : Correlation and application
(Elsevier, 1969-07)
In order to evaluate the striking discrepancy between the experimental ease of polarographic reduction of adenine and cytosine, and that predicted by molecular orbital calculation, the electrochemical oxidation-reduction ...
Uranium chalcogenides--II Heat capacities and thermodynamic properties of US2 and US3 from 5 to 350[deg]K
(Elsevier, 1968-08)
Heat capacity measurements and calculations of thermodynamic properties have been carried out for the compounds US2 and US3 from 5 to 350[deg]K. The temperature dependence of the heat capacities is of normal sigmate type, ...
Purification and properties of an acid phosphomonoesterase from Neurospora crassa
(Elsevier, 1961-09-02)
An acid phosphomonoesterase was purified 1400-fold from mycelium of Neurospora crassa with a 40% recovery. The enzyme had a pH maximum of 5.6 with [beta]-glycerol phosphate or glucosamine 6-phosphate as substrates, and ...
