Optical probe study of a nonentangling macromolecule solution--bovine serum albumin: Water
(Elsevier, 1985-06)
The diffusion coefficient D of polystyrene latex spheres in bovine serum albumin:water was studied as a function of protein concentration c for 0 c D fails by as much as 25 to 50%, D being larger than predicted from the ...
Quarter field resonance and integer-spin/half-spin interaction in the EPR of Thermus thermophilus ferrodoxin. Possible new fingerprints for three iron clusters
(Elsevier, 1985-04-29)
We describe two new characteristics of the EPR of the seven-iron containing ferrodoxin from Thermus thermophilus. First, the reduced state of the 3Fe center, which has traditionally been considered to be EPR-silent, has ...
Stereospecific synthesis of [gamma]-butyrolactones from acyclic vinyl sulfoxides: an asymmetric synthesis of optically pure oak lactones
(Elsevier, 1985)
The sulfoxide-directed lactonization of several trisubstituted vinyl sulfoxides with dichloroketene proceeds in a completely stereospecific manner. The lactonization of (E) -3 (R) --tolylsulfinyloctene occurs with complete ...
Formation And Characterization of Amorphous Erbium-Based Alloys Prepared By Near-Isothermal Cold-Rolling of Elemental Composites
(American Institute of Physics, 1985)
Function of ribosomes and glutamyl-tRNA isoacceptors in protein synthesis in regenerating skeletal muscle
(Elsevier, 1985-04-19)
Ribosomes from 8-day-regenerating rat skeletal muscle have been shown to be more active in poly(U)-directed polyphenylalanine synthesis than ribosomes from control muscle. This difference persists after salt washing of the ...
Fischer-Tropsch synthesis on bimetallic ruthenium-gold catalysts
(Elsevier, 1985-06)
The effect of Au in the behavior of Ru as a Fischer-Tropsch catalyst was studied. Two series of catalysts were investigated, one supported on SiO2 and the other on MgO. Au did not seem to alter the product distribution on ...
Protein synthesis by hepatic mitochondria isolated from carbon tetrachloride-exposed rats
(Elsevier, 1985-03-20)
Hepatic mitochondria isolated from rats 40 h after dosage with 1.1 ml/kg CCl4 are uncoupled and display structural damage. Mitochondrial function returns during hepatic recovery. Because the products of mitochondrial protein ...
Regulation of amino acid transport system L by amino acid availability in CHO-K1 cells. A special role for leucine
(Elsevier, 1985-10-10)
Starvation of CHO-K1 cells for leucine leads to a 3-4-fold increase in transport system L activity, without modification of transport through systems A and ASC. The concentration of leucine must be below 10 [mu]M before ...
Carbazole-substituted dehydroalanine main chain polymers. Synthesis and characterization of poly[methyl 2-(9-carbazolyl) acetylaminopropenoate] and poly[2-(9-carbazolyl) acetylaminopropenoic acid]
(John Wiley & Sons, Inc., 1985-12)
The preparation and radical-initiated polymerization of a carbazole-substituted N -acylated dehydroalanine, namely, 2-(9-carbazolyl)acetylaminopropenoic acid ( 7 ) and its methyl ester ( 6 ) is reported. The monomers 6 ...
