Zusammenfassung

Die Einwirkung in vitro von 6 ANAD, dem 6-Aminonicotinsäureamid-Analogen des NAD, auf ATP:Pyruvatphosphotransferase (Pyruvatkinase) und ATP:Kreatinphosphoryltransferase (Kreatinphosphokinase) aus Kaninchenmuskel wird untersucht. In Konzentrationen von 10−3 M hemmt 6 ANAD diese Reaktionen (in Richtung der Phosphorylierung des ADP zum ATP) um ca. 40%.

Summary

The in vitro effects of 6 ANAD, the 6-aminonicotinic acid amide-analogue of NAD, on ATP : pyruvate phosphotransferase (pyruvate kinase) and ATP:creatine phosphoryltransferase (creatine phosphokinase) of rabbit muscle was investigated. 6 ANAD inhibits these reactions performed as phosphorylations of ADP to ATP in 10−3 molar concentrations about 40 per cent.
