TLDR
Multiple inhibition studies show that phosphate, sulfate, and acetate as inhibitors of pyridoxal-P binding are all competing for the same site, which appears to bind divalent anions tighter than monovalent anions and is sterically hindered for binding long chain carboxylic acids and phenylphosphate.

The Role of Acetaldehyde in Mediating the Deleterious Effect of Ethanol on Pyridoxal 5′-Phosphate Metabolism

TL;DR: The hypothesis that the deleterious effect of ethanol oxidation on pyridoxal phosphate metabolism is mediated at least in part by acetaldehyde which displaces this coenzyme from protein binding, thereby enhancing its degradation is supported.

L-Glutamate decarboxylase from bacteria.

TL;DR: Typical results of purification of the enzyme from E. coli harvested from 90 liters of medium or approximately 500 g of cell paste are presented in a tabulated form in this chapter.

Mechanism of the stereospectific irreversible inhibition of bacterial glutamic acid decarboxylase by (R)-(--)-4-aminohex-5-ynoic acid, an analogue of 4-aminobutyric acid.

TL;DR: If the decarboxylation of glutamate occurs with retention of configuration, the irreversible inhibition of this enzyme by the 4-(R) isomer can be rationalized on the basis of reversibility of the protonation step in the normal catalytic mechanism.

Determination of molecular weights and frictional ratios of proteins in impure systems by use of gel filtration and density gradient centrifugation. Application to crude preparations of sulfite and hydroxylamine reductases

TL;DR: With a Stokes radius measured by the chromatographic method and a sedimentation coefficient determined by density gradient centrifugation, reasonable estimates for both the molecular weight and the frictional ratio (f/f0) of a macromolecule are available.

Studies on liver alcohol hydrogenase complexes. 3. multiple inhibition kinetics in the presence of two competitive inhibitors.

TL;DR: The present kinetic analysis quantitatively reconfirmed the previous conclusion that o-phenanthroline and adenosine diphosphate ribose interact independently with different sites of the enzyme.

Isolation and Characterization of Multiple Forms of Glutamate-Aspartate Aminotransferase from Pig Heart

TL;DR: Electrophoretic analyses carried out on a water extract of a single heart taken immediately after the death of the animal reveal the presence of the various subforms, indicating either that theVarious subforms exist as such in the living cell or, if they are artifacts, that they must be formed very early in the preparation and under extremely mild conditions.
