Spectroscopic and scattering investigation of isopoly-molybdate and tungstate solutions
(Elsevier, 1984)
Detailed spectroscopic and scattering investigations of isopoly-molybdate and -tungstate solutions as a function of concentration and pH were made. From scattering results the apparent molecular weights were determined as ...
Vibrational analysis of peptides, polypeptides, and proteins. XXIV. Conformation of poly(Α-aminoisobutyric acid)
(Wiley Subscription Services, Inc., A Wiley Company, 1984-10)
Raman and polarized ir spectra have been obtained on built-up monomolecular films of poly(Α-aminoisobutyric acid), and analyzed in the context of normal mode calculations on 3 10 -, Α-, and Α′-helix conformations of this ...
Vibrational analysis of peptides, polypeptides, and proteins. XXI. Β-Calcium-poly( L -glutamate)
(Wiley Subscription Services, Inc., A Wiley Company, 1984-08)
The observed Raman and ir spectra of Ca-poly( L -glutamate) in the Β conformation have been analyzed by means of a normal mode calculation. The force field for the main chain was transferred without refinement from Β-poly( ...
DNA polymerase in nuclei isolated from herpes simplex virus type-2-infected cells. Characterization of the reaction product and inhibition by substrate analogs
(Elsevier, 1984-02-24)
Nuclei isolated from herpes simplex virus (HSV) type 2-infected KB cells were examined for their capacity to serve as an in situ source of herpes DNA polymerase. In contrast to purified enzymes with added template, approx. ...
Estimation of acyldihydroxyacetone phosphate and lysophosphatidate in animal tissues
(Elsevier, 1984-11-14)
Chemical and enzymatic methods have been developed to measure small quantities (10-8-10-10 mol) of acyldihydroxyacetone phosphate in animal tissues. Lipids extracted from tissue samples with acidic CHCl3/ methanol were ...
Nicotinamide adenine dinucleotide (NAD+). Formal potential of the NAD+/NAD[middle dot] couple and NAD[middle dot] dimerization rate
(Elsevier, 1984-03-30)
The rate constant, kd, for the dimerization of the free radical (NAD[middle dot]), produced on the initial one-electron reduction of NAD+, was measured by double potential-step chronoamperometry, fast-scan cyclic voltammetry ...
Synthesis of N-acetyllactosamine containing a -[6-3H]galactopyranosyl group
(Elsevier, 1984-07-01)
A simple and convenient method for the introduction of radiolabel onto C-6' of N-acetyllactosamine is described. 1-N-Benzyl-3-O-[beta]--galactopyranosyl--arabinosylamine (1) was synthesized from 3-O-[beta]--galactopyrano ...
Dual-mode EPR spectrometry of O2-pulsed cytochrome c oxidase
(Elsevier, 1984-06-26)
O2-activated bovine heart cytochrome c oxidase has been examined by dual-mode EPR spectrometry. Resonances have been observed at g = 10 and 4.5 in the parallel mode and at g = 10, 5, 1.8 and 1.7 in the normal mode. The ...
