Studies of 3-aminopyridine adenine dinucleotide phosphate.
3-Aminopyridine adenine dinucleotide phosphate (AADP) was prepared from NADP and 3-amino-pyridine through the pig brain NADase-catalyzed pyridine base exchange reaction. The purified dinucleotide was chemically characterized and spectral properties of the compound were determined. The importance of the application of AADP in studies of NADP-requiring biochemical processes was indicated by the demonstration of AADP as an effective inhibitor of five NADP-requiring enzymes, by the demonstration of the fluorescence enhancement on the binding of AADP to yeast glucose-6-phosphate dehydrogenase when glucose-6-phosphate is present, and by the functioning of AADP as a fluorimetric substrate for snake venom nucleotide pyrophosphatase.
