The oxidation-reduction potentials of parsley ferredoxin and its selenium-containing homolog
(Elsevier, 1971-08-06)
We have measured the oxidation-reduction potential of parsley ferredoxin and its derivative in which the two atoms of labile sulfide have been replaced by selenide. The values are -0.416 V (25[deg], pH 7.94) and -0.378 V ...
Variant properties of bovine liver 2-keto-4-hydroxyglutarate aldolase; its [beta]-decarboxylase activity, lack of substrate stereospecificity, and structural requirements for binding substrate analogs
(Elsevier, 1971-10-20)
1. 1. 2-Keto-4-hydroxyglutarate aldolase (2-oxo-4-hydroxyglutarate glyoxylatelyase; reaction: 2-oxo-4-hydroxyglutarate [left harpoon over right] pyruvate + glyoxylate) catalyzes the cleavage and the formation of both optical ...
Isoenzymes of carbonic anhydrase I from primate red blood cells
(Elsevier, 1971-04-27)
The electrophoretic patterns of the multiple forms of carbonic anhydrase I were examined from the red cells of two species of macaque monkeys and orangutan. In the rhesus macaque, Macaca mulatta, it was possible to generate ...
Thermodynamics of polynuclear aromatic molecules I. Heat capacities and enthalpies of fusion of pyrene, fluoranthene, and triphenylene
(Elsevier, 1971-01)
The heat capacities of three crystalline condensed-ring aromatic substances were studied from 5 to 350 K by adiabatic cryogenic calorimetry and into the liquid phase with the intermediate-range adiabatic calorimeter. The ...
Structure analyses combining electron diffraction and microwave data : I. Study of XeOF4
(Elsevier, 1971-06)
Molecular parameters for XeOF4 derived from electron diffraction data are compared with those previously reported in vibrational and rotational spectroscopic studies of the molecule. Additional least-squares calculations ...
Studies in molecular structure, symmetry and conformation I
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Company Limited ; Springer Science+Business Media, 1971-04)
Crystals of 1-aminocyclooctanecarboxylic acid hydrobromide are orthorhombic, with a = 26·026, b =7·087, c = 6·149, Z = 4 and space group P 2 1 2 1 2 1 .The structure was solved in projections by direct methods and later ...
Biosynthesis, in vitro, of "histidine-protein" -- A biochemical marker in epidermal differentiation
(Elsevier, 1971-04-29)
Unusual protein containing a high level of histidine and eight other amino acids (i.e. glycine, alanine, serine, threonine, arginine, glutamic acid, aspartic acid and tyrosine) is localized in the epidermal granular cell ...
Confined jet mixing in the entrance of a tubular reactor
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1971-05)
The equations for the conservation of momentum and mass were solved numerically for the region downstream from the exit of an axial jet into a confined annular stream of the same fluid. An implicit, alternating direction ...
Purification and characterization of glycolic acid oxidase from pig liver
(Elsevier, 1971-03-10)
1. 1. A procedure for the isolation of glycolic acid oxidase (glycolate:O2 oxidoreductase, EC 1.1.3.1) from pig liver is described. The enzyme has been crystallized and the amino acid composition has been determined.2. 2. ...
