Characterization of the [omega]-hydroxylase of Pseudomonas oleovorans as a nonheme iron protein
(Elsevier, 1977-10)
The [omega]-hydroxylase of Pseudomonas oleovorans, which catalyzes the hydroxylation of fatty acids and alkanes and the epoxidation of alkenes in the presence of a reduced pyridine nucleotide, a reductase, rubredoxin, and ...
Free carboxylate groups required for transport of neutral amino acids by the Ehrlich ascites-tumor cell
(Elsevier, 1977-03-01)
Although uncharged structures analogous to the carboxyl group of the amino acid molecule have served in place of that group for transport into some cells, we find that substitution either by the carboxamide group or by the ...
Thermodynamics of the lanthanide halides II. Heat capacities and Schottky anomalies of SmCl3, EuCl3, and GdCl3 from 5 to 350 K
(Elsevier, 1977-01)
The heat capacities of SmCl3, EuCl3, and GdCl3 have been measured from 5 to 350 K by adiabatic calorimetry. For SmCl3 and EuCl3, the calculated Schottky heat capacities may be compared with the difference in heat capacity ...
Heat capacities of HfB2.035 and HfC0.968 from 5 to 350 K
(Elsevier, 1977-03)
Heat capacities were determined by adiabatic calorimetry on well-characterized samples of HfB2.035 and HfC0.968. The results are simply sigmoid except for a peak in the first derivative of the HfB2 smoothed results (not ...
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 ...
An immobilized naphthylamide substrate for proteinases with tryptic-like specifleity
(Elsevier, 1977-12)
An immobilized amino acid naphthylamide substrate for proteinases with tryptic-like specificity was prepared by reacting -arginine [beta]-naphthylamide with an N-hydroxysuccinimide-activated derivative of agarose. Hydrolysis ...
Hormonal regulation of membrane phenotype
(Alan R. Liss, Inc.Wiley Periodiocals, Inc., 1977)
Incubation of rat hepatoma cells (HTC) in tissue culture with glucocorticoids alters several membrane properties characteristic of transformed cells, without affecting the growth rate of these cells. Variant cell lines ...
Decrease in specific activity of heart and muscle aldolase in old mice
(Elsevier, 1977)
1. 1. Aldolase was purified from mouse heart and muscle cells by column chromatography. The enzyme from 3- and 30-month old mouse tissues was assayed under different temperature and pH conditions in order to determine the ...
Interaction of pneumococcal S-14 polysaccharide with lectins from Ricinus communis, Triticum vulgaris, and bandeiraea simplicifolia
(Elsevier, 1977-09)
Two purified lectins, namely, wheat-germ agglutinin (from Triticum vulgaris) and the hemagglutinin from Ricinus communis seeds, readily form a precipitate with pneumococcal S-14 polysaccharide, whereas the Bandeiraea ...
