125I-N6-(N-[6-N-(5-iodo-4-azidosalicyl)-aminohexyl]- aminocarbamoylmethyl)-nicotinamide adenine dinucleotide (125I-N6-I-ASA-AH-NAD+) was synthesized by coupling N6-([6-aminohexyl]-carbamoylmethyl)-NAD+ with 4-azidosalicylic acid N-hydroxysuccinimide ester followed by radioiodination. The utility of 125I-N6-I-ASA-AH-NAD+ as an effective site-directed photoprobe was demonstrated by the photolabeling of both glutamate dehydrogenase and 15-hydroxyprostaglandin dehydrogenase. Both enzymes can be saturated with labeled probe with apparent dissociation constants comparable to those reported for NAD+. Photoincorporation of the probe into both enzymes was found to be protected specifically by NAD+. These results indicate that 125I-N6-I-ASA-AH-NAD+ can be a specific photoprobe for NAD(+)-linked enzymes.
