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 ...
2-acetamido-2-deoxy-[alpha]--galactosidases of clostridium perfringens. Separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]--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 0.32-0.36 ...
Electrochemical reduction of thymine in dimethyl sulfoxide autoprotonation of the radical anion and reduced free radical
(Elsevier, 1979-09-25)
Thymine is reduced in dimethyl sulfoxide (E1/2 of -2.4 V); the decrease in apparent faradaic n from one at inifinite dilution to two-thirds at concentraitons above 2 mM is due to proton transfer by thymine to the initially ...
Electron diffraction study of the molecular structure of bis(trifluoromethyl)peroxide
(Elsevier, 1977-07)
The following structural parameters and estimated standard deviations (3[sigma]) have been found for (CF3O)2,: rg, (O-O) = 1.419 +/- 0.020 A, rg (C-O) = 1.399 +/- 0.009 A, rg (C-F) = 1.320 +/- 0.003 A, [angle](C-O-O) = ...
Phonon Raman spectra, molecular motions, and phase transitions of dimethylacetylene crystal
(Elsevier, 1973-07-15)
The phonon Raman spectra of crystals of dimethylacetylene, perdeutero-dimethylacetylene and their mixtures have been investigated down to 20[deg]K. The high temperature phase shows only one line and the low temperature ...
Adenine nucleotide translocation in liver mitochondria of hypothyroid rats
(Elsevier, 1977-01-30)
In measurements using a disc filtration method, liver mitochondria obtained from hypothyroid rats translocate external ADP at 0 [deg]C via the atractyloside-sensitive carrier much more slowly than do mitochondria from ...
Determination of acyl-CoA concentrations using pancreatic lipase
(Elsevier, 1971-11-13)
A rapid and sensitive assay for acyl-CoA thiol esters has been devised using pancreatic lipase as a hydrolytic agent in the presence of dithionitrobenzoic acid to detect the liberated CoA. Acyl thiol esters containing 12-22 ...
