A model of how the sickle-cell gene produces malaria resistance
(Elsevier, 1975-03)
A model of resistance to falciparum malaria provided by the sickle-cell gene in heterozygous state is presented based on earlier hypotheses, the life cycle of P. falciparum within its human host, and the nature of host ...
NMR evidence for an acetylcholine ATP complex
(Elsevier, 1975-06-02)
The interaction of acetylcholine with ATP was studied using proton NMR. T1 measurements indicate the formation of a complex with a probable composition of four (4) acetylcholine molecules for each ATP molecule.
The stereospecificity of alcohol oxidases from Tanacetum Vulgare and Candida Boidinii
(Elsevier, 1975-12-01)
The stereospecificity of the oxidation of trans-hex-2-en-1-ol and ethanol was determined for alcohol oxidases from leaves and from the yeast . It was found that both enzymes remove the pro-1R hydrogen. The enzyme from ...
Allozyme genetics in permanent translocation heterozygotes of the Oenothera biennis complex
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-08)
Allozyme inheritance and transmission genetics of 11 enzyme systems were determined in the permanent translocation heterozygotes Oenothera biennis, Oe. strigosa , and Oe. parviflora . Electrophoretic variation was examined ...
Simulation of differential effects on rates in membrane transport
(Elsevier, 1975-02)
Solute uptake by a mobile carrier mechanism has been simulated with an analog computer for the case where the movement of the carrier across the membrane is rate-limiting. The ratio of the rate constants for the translocation ...
Crystallographic characterization of flavodoxin from Anacystis nidulans
(Elsevier, 1975-05-05)
Flavodoxin isolated from the blue-green alga, Anacystis nidulans, crystallizes from ammonium sulfate in space group P212121, with a = 57.08 A, B = 69.24 A and C = 45.55 A. The diffraction patterns extend to a resolution ...
Use of [1 or 3-3H, U-14c]glucose to estimate the synthesis of glycerolipids via acyl dihydroxyacetone phosphate
(Elsevier, 1975-07-22)
SummaryBHK-21-cl3 fibroblasts were incubated with [1-3H, U-14c]glucose or [3-3H, U-14c]glucose to produce intracellular [3H]NADPH via the phosphogluconate pathway. 3H and 14C were then determined at the three positions of ...
A general analysis of resource allocation by competing individuals
(Elsevier, 1975-08)
The analysis presented in this paper is constructed to determine the pattern of resource allocations among competing individuals of the same and/or different species in some defined habitat. Competing individuals have at ...
