title: Affinity chromatography on immobilised triazine dyes. Studies on the interaction with multinucleotide-dependent enzymes.
abstract: A systematic investigation into the interaction of several triazinyl dyes with two enzymes from purine metabolism, IMP dehydrogenase (IMP: NAD+ oxidoreductase, EC 1.2.1.14( and adenylosuccinate synthetase (IMP: L-aspartate ligase (GDP-forming), EC 6.3.4.4) has been conducted. Evidence from kinetic inhibition studies, enzyme inactivation with specific affinity labels and specific elution techniques from agarose-immobilised dyes indicate that triazine dyes such as Procion Blue H-B (Cibacron Blue F3G-A), Red HE-3B and Red H-3B are able to differentiate between the nucleotide-binding sites of these enzymes. This information has been exploited to design specific elution techniques for the purification of these enzymes by affinity chromatography.
