Peptide Acceptors in the Arginine Transfer Reaction

Peptide acceptors in the leucine, phenylalanine transfer reaction.

The reaction of choline dehydrogenase with some electron acceptors.

1. The choline dehydrogenase (EC 1.1.99.1) WAS SOLUBILIZED FROM ACETONE-DRIED POWDERS OF RAT LIVER MITOCHONDRIA BY TREATMENT WITH Naja naja venom. 2. The kinetics of the reaction of enzyme with phenazine methosulphate and ubiquinone-2 as electron acceptors were investigated. 3. With both electron acceptors the reaction mechanism appears to involve a free, modified-enzyme intermediate. 4. With s...

Direct Energy Transfer in Systems of Polymerized Acceptors

We study the direct incoherent energy transfer from an immobile excited donor molecule to acceptor molecules, which are all attached to polymer chains, randomly arranged in a viscous solvent. The decay forms are found explicitly, in terms of an optimal-fluctuation method, for arbitrary confomations of polymers. Long-range transfer of excitation energy from excited donor to acceptor molecules, i...

Kinetic studies on the arginine kinase reaction.

A highly purified preparation of arginine kinase from the tail muscle of the crayfish, Panulirus longipes, has been used to investigate the mechanism of the reaction. The results of initial velocity, product inhibition, and isotope exchange at equilibrium studies are consistent with the reaction having a random mechanism in which all the steps are in rapid equilibrium except those concerned wit...

Thermodynamics of the arginine kinase reaction.

The effect of temperature, pH, free [Mg(2+)], and ionic strength on the apparent equilibrium constant of arginine kinase (EC 2.7.3.3) was determined. At equilibrium, the apparent K' was defined as [see text] where each reactant represents the sum of all the ionic and metal complex species. The K' at pH 7.0, 1.0 mM free [Mg(2+)], and 0. 25 M ionic strength was 29.91 +/- 0.59, 33.44 +/- 0.46, 35....
