Evidence for a novel flavin prosthetic group associated with NADH dehydrogenase from Peptostreptococcus elsdenii
(Elsevier, 1971-05-12)
1. 1. NADH dehydrogenase (EC 1.6.99.3) has been purified from the strictly anaerobic rumen bacterium Peptostreptococcus elsdenii. The purified protein is specific for NADH as electron donor; it can use 2,6-dichlorophenolindophenol ...
Electrophilic alkylation of 1-SB9H9
(Elsevier, 1977-06-21)
Reaction of closo-1-SB9H9 with either ethyl or methyl iodide in the presence of A1C13 produces alkylated derivatives of the type 1-SB9H(9-x)Rx (R = C2H5, CH3;x = 1---5), which were identified by GC/MS, 11B and 1H NMR ...
The purification and properties of an alcohol dehydrogenase from mouse liver
(Elsevier, 1974-04)
1. 1. An alcohol dehydrogenase (alcohol: NAD oxidoreductase, EC ( [middle dot] [middle dot] ) was isolated from the supernatant fraction of mouse liver and purified 206-fold.2. 2. A number of aliphatic aldehydes, ranging ...
Destruction and resynthesis of mouse [beta]-glucosidases
(Elsevier, 1979-02-01)
1. 1. Injection of a single dose of conduritol B epoxide into mice produced almost complete destruction of glucocerebrosidase ( glucohydrolase, EC 3.2.1.45) in liver, spleen, brain, and kidney within 5 h. Restoration of ...
Soluble cytochrome b5 reductase from human erythrocytes
(Elsevier, 1972-07-12)
1. An enzyme that catalyzes the reduction of erythrocyte cytochrome b5 has been isolated from the supernatant fraction of erythrocyte hemolysates by chromatography on DEAE-cellulose, Amberlite CG-50, and Bio-Gel P-60.2. ...
Determination of anserine, carnosine, and other histidine compounds in muscle extractives
(Elsevier, 1971-01)
A method for the determination of anserine, carnosine, homocarnosine, histidine, 1-methylhistidine, and 3-methylhistidine with the Phoenix amino acid analyzer is described. A study of the separation of these compounds on ...
The enthalpies of combustion and formation of [2.2]-paracyclophane and triptycene
(Elsevier, 1973-09)
The enthalpies of combustion, ΔHoc, for crystalline [2.2]-paracyclophane (C16H16) and triptycene (C20H14) have been measured by oxygen combustion calorimetry. The derived standard enthalpies of formation at 298.15 ...
Electron diffraction study of the molecular structure of trifluoromethyl hypofluorite
(Elsevier, 1971-06)
The following structural parameters and estimated standard deviations were found for trifluoromethyl hypofluorite: rg(C-F) = 1.319 +/- 0.003 A, rg(C-O) = 1.395 +/- 0.006 A, rg(O-F) = 1.421 +/- 0.006 A, [angle-measured](F-C-F) ...
Nephrotoxic effects of tetanus toxin: An ultrastructural study
(Elsevier, 1975-12)
Generalized nephrotoxicity was observed in the rat as early as 6 hr after intramuscular injection of 1000 of tetanus toxin. The most striking morphological changes, including swelling and rupture of the mitochondria, ...
2-acetamido-2-deoxy-[alpha]-D-galactosidases of clostridium perfringens. separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]-D-galactosidases have been separated from filtrates of cultured Clostridium perfringens by electrophoresis in 6.5% poly(acryl-amide) gels. One of the enzymes had a mobility of ...
