Abstract
1. The suitability of cellulose and Sepharose as supports for affinity chromatography of two groups of cofactor-linked enzymes, dehydrogenases and kinases, was examined. Sepharose was found to be superior. 2. The selective capacities of the columns were measured by frontal analysis and are discussed in relation to the nucleotide contents. 3. The effect of various concentrations of enzyme and of non-specific protein on the performance of the affinity columns, and the effects of equilibration time, flow rate, sample volume and dilution of the nucleotide were examined. 4. The effect of interposing polymethylene and polyglycine extension arms between the matrix backbone and the nucleotide was investigated for several cofactor-dependent enzymes. Maximum binding was observed with an extension arm 0.8–1nm long.
