Characterization of cytosolic forms of CTP: choline-phosphate cytidylyltransferase in lung, isolated alveolar type II cells, A549 cell and Hep G2 cells
(Elsevier, 1989-12-18)
The subcellular forms of cytidylyltransferase (EC 2.7.7.15) in rat lung, rat liver, Hep G2 cells, A549 cells and alveolar Type II cells from adult rats were separated by glycerol density centrifugation. Cytosol prepared ...
Assay and properties of the enzyme catalyzing the biosynthesis of 1-O-alkyl dihydroxyacetone 3-phosphate
(Elsevier, 1981-10-01)
The properties of the enzyme alkyl dihydroxyacetone phosphate synthase (1-O-acyl dihydroxyacetone 3-phosphate + ROH --> 1-O-alkyl dihydroxyacetone 3-phosphate + fatty acid) in Ehrlich ascites tumor cell microsomes were ...
Are cationic [eta]3-allyl complexes general precursors to metallacyclobutanes? Synthesis and structure of [mu]-chloro-bis[([eta]3-allyl)-2,2'-bipyridyldicarbonylmolybdenum(II)] tetrafluoroborate
(Elsevier, 1984-08-28)
Silver tetrafluoroborate reacts with Cl(bipy)(CO)2([eta]3-C3H5)Mo in CH2Cl2 to give the dimeric cation, ([mu]-Cl)[(bipy)(CO)2([eta]3-C3H5)Mo]2+, isolated as the crystalline BF4- salt with CH2Cl2 of solvation (5). Complex ...
Expert system for interpretation of the infrared spectra of environmental mixtures
(Elsevier, 1988)
A program for the identification of the principal components of mixtures through interpretation of the infrared mixture spectrum (IntIRpret) was developed. This program, which was developed as a preliminary screening tool ...
1,4-Additions of the highly functionalized copper reagents RCu(CN)ZnI [middle dot] 2 BFP3 to trisubstituted enones. A new BF3 promoted cyclization reaction
(Elsevier, 1988)
The new copper reagents RCu(CN)Zn I [middle dot] 2 BF3 1 containing various functional groups like esters, cyanides, chlorides or enoates react with [beta], [beta]'- disubstituted enones to afford the Michael adducts 4-7 ...
Calcium compartmentation in isolated renal tubules in suspension
(Elsevier, 1988-04)
Substantial increases of total cell Ca2+ have been observed in suspensions of isolated rabbit proximal tubules subjected to hypoxic injury or treated with exogenous ATP followed by apparent recovery with reoxygenation of ...
[omega]-1 and [omega]-2 hydroxylation of prostaglandins by rabbit hepatic microsomal cytochrome P-450 isozyme 6
(Elsevier, 1985-11-15)
Incubation of prostaglandin E1 (PGE1) with liver microsomes from control rabbits and from rabbits treated with ethanol or imidazole yielded 18-, 19-, and 20-hydroxy metabolites, representing hydroxylation at [omega]-2, ...
The thermodynamics of the divalent metal fluorides. III. Heat capacity of the fast ion conductor SrSnF4 from 6 to 344 K
(Elsevier, 1989-07)
The heat capacity of the fast ion conductor SrSnF4 was measured by adiabatic calorimetry from 6 T/K 19F spin-lattice relaxation time T1 occurs. Standard molar thermodynamic functions are given at selected temperatures from ...
Vibrational spectra, assignments and normal coordinate analyses for crystalline zirconium tetrachloride and tetrabromide
(Elsevier, 1981)
Raman and far-IR spectra have been obtained of crystalline ZrCl4 and ZrBr4. The observed frequencies have been interpreted on the basis of the C2h symmetry of the Bravais unit cell and have been subjected to a normal ...
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, ...
