ENZYMATIC PREPARATION OF TRIPHOSPHOPYRIDINE NUCLEOTIDE FROM DIPHOSPHOPYRIDINE NUCLEOTIDE

Preparation of triphosphopyridine nucleotide.

Enzymatic Synthesis of Triphosphopyridine Nucleotide

Von Euler and Vestin (1) demonstrated the synthesis of triphosphopyridine nucleotide (TPN) when diphosphopyridine nucleotide (DPN) was incubated with adenosine triphosphate (ATP) in the presence of crude yeast maceration juice. In subsequent reports (2) from the Stockholm laboratory, several mechanisms for this reaction were considered but none was established. With crude pigeon liver fractions...

Enzymatic studies with analogues of diphosphopyridine nucleotide.

It has been previously shown (l-3) that the nicotinamide moiety of diphosphopyridine nucleotide can be replaced by other pyridine bases without the loss of the coenzyme function. The observation that both the 3-acetylpyridine and pyridine-3aldehyde analogues of diphosphopyridine nucleotide function as coensymes with various dehydrogenases (3) indicated that the amide group on DPN was not essent...
