title: [Coenzym properties of some Ade-1- and Ade-N6-substituted NAD derivatives (author's transl)].
abstract: By reaction of NAD with different oxiranes or with aziridine, derivatives of the coenzyme are obtained with substituents in position 1 or on the amino group in position 6 of the adenine ring. While the Ade-1-substituted derivatives show high Km values with different dehydrogenases and are reduced only very slowly by these enzymes, the coenzyme derivatives substituted at the amino group behave very similarly to NAD. Correlations were found between coenzyme efficiency of the compounds and the lipophilic character of their substituents. The results can be interpreted from the structure of the active site of the dehydrogenases investigated.
