The preparation and characterization of phosphorylated derivatives of histidine
(Elsevier, 1968-02-12)
1. Phosphorylated derivatives of histidine were synthesized and studied in order to provide a better understanding of the chemistry of phosphohistidine-containing proteins. 1-Phosphohistidine, 1,3-diphosphohistidine, ...
A simple computer circuit for automatic spectrophotometric analysis of binary mixtures by differential reaction rates
(Elsevier, 1965-05)
A simple analogue computer circuit, for application with a continuous reading spectrophotometer to give automatic analysis of binary mixtures of closely related substances using a differential reaction rate technique, is ...
Effects of ethylenic bond position upon acyltransferase activity with isomeric cis-octadecenoyl coenzyme a thiol esters
(Elsevier, 1969-04-29)
The specificity of the acyl-CoA:phospholipid acyltransferases has been studied using the 16 positional isomers of cis-octadecenoic acid. The results showed that the acyl-transferases acting at both the 1- and 2-positions ...
Determination of the possible conformations of the residues linked in a polypeptide chain
(Wiley Subscription Services, Inc., A Wiley Company, 1965-05)
No Abstract.
Stereochemical criteria for polypeptides and proteins : VI. Non-bonded energy of polyglycine and poly--alanine in the crystalline [beta]-form
(Elsevier, 1968-12-03)
This paper describes calculations on the packing energy in the crystal structures of [beta]-forms of polyglycine and poly--alanine. It is shown that the non-bonded interactions between [beta]-chains, in a pleated sheet ...
Evaluation of lipoprotein size–density distributions from sedimentation coefficient distributions obtained at several solvent densities. I. Theory
(Wiley Subscription Services, Inc., A Wiley Company, 1969-01)
A method is presented for the treatment of distribution functions obtained by ultra-centrifugal sedimentation velocity experiments on the plasma lipoproteins, so that adequate corrections can he made for the effects of ...
The inhibition of phosphoribosyl-pyrophosphate amidotransferase activity by cordycepin monophosphate
(Elsevier, 1964-09-18)
1. 1. Cordycepin monophosphate has been shown to inhibit the activity of phosphoribosyl-pyrophosphate amidotransferase (ribosylamine-5-phosphate:phyrophosphate phosphoribosyltransferase (glutamate-amidating), EC 2.4.2.14) ...
Force fields for nitriles
(Elsevier, 1968-11)
A valence force field for nitriles based on the force field obtained for hydrocarbons is found to give very good agreement with the observed bands for several mono- and di-nitrile molecules. The average deviation between ...
Studies on the estimation of deoxyribonucleic acid and ribonucleic acid in rat brain
(Elsevier, 1963)
A method for the estimation of DNA and RNA in rat brain is described. The principal modifications of preexisting methods involve initial lipid extraction with chloroform-methanol and continuous stirring during alkaline ...
