Synthetic models of metalloenzymes
(Elsevier, 1983)
Metal ions play an important role in the enzymic catalysis of many metalloproteins. The molecular details of the catalytic cycle are often obscured by the complexity of the biological system. It has been the goal of our ...
The kinetics and mechanism of oxidation of reduced spinach ferredoxin by molecular oxygen and its reduced products
(Elsevier, 1983-06-30)
Reduced spinach ferredoxin reacts with molecular oxygen in an autocatalytic reaction characterized by a hyperbolic dependence on oxygen concentration. The kinetics of the reaction indicate formation of a reduced ferredoxin-oxygen ...
Free fatty acids in an animal model of reye's syndrome
(Elsevier, 1983-09-20)
Recent studies have indicated that viral infections, aspirin treatment and hyperammonemia are associated with Reye's syndrome. It has also been reported that free fatty acids in serum and total lipids in the liver of Reye's ...
SYN -1,4-addition of carboxylate salts to cyclic allylic epoxides mediated by cuprous chloride
(Elsevier, 1983)
A mild method for the 1,4- opening of certain cyclic allylic epoxides has been found, using sodium carboxylates in the presence of cuprous chloride.
Dimerization occurs during the reversible acid inactivation of 2-oxo-4-hydroxyglutarate aldolase from Escherichia coli
(Elsevier, 1983-11-28)
Exposure of Escherichia coli 2-oxo-4-hydroxyglutarate aldolase (4-hydroxy-2-oxoglutarate glyoxylate-lyase, EC 4.1.3.16) (molecular WEIGHT = 63000) to phosphoric acid at pH 1.6 for 10 min at 4[delta]C causes 95% or greater ...
Fate of intravenously administered high-density lipoprotein labeled with radioiodinated cholesteryl oleate in normal and hypolipidemic rats
(Elsevier, 1983-03-01)
Radioiodinated cholesteryl oleate (125I-CO) was found to associate rapidly with plasma lipoproteins following intravenous administration to rats. The high-density lipoprotein (HDL) fraction was observed to contain the ...
Stacking Characteristics of Composite Cardboard Boxes
(Sage Publications, 1983)
This paper presents a simplified model and method for finding the deflection char acteristics of stacked cardboard boxes, provided the load-deflection characteristic of the box is known. A computer program, based on this ...
Small angle X-ray scattering, O. Clatter and O. Kratky, Academic, New York, 1982,515 pp. No price given
(John Wiley & Sons, Inc., 1983-06)
No Abstract.
Mutarotation of optically active poly( cis -5-ethyl- D -proline)
(John Wiley & Sons, Inc., 1983-06)
The mutarotation between form I and form II of poly( cis -5-ethyl- D -proline) has been experimentally realized. A number of hydrogen-bond-forming solvents have been found effective in initiating the mutarotational process. ...
Is cytochrome aa3 from thermus thermophilus a single subunit oxidase?
(Elsevier, 1983)
A reliable procedure has been developed for the purification of the cytochrome c1aa3 complex from the plasma membrane of T. thermophilus. The ratios heme C:heme A:Fe:C were found to be 1:2:3:2 confirming previous results, ...
