[Possible participation of pyrophosphate in ADP and ATP biosyntheses from exogenous adenine by a culture of Corynebacterium species VSTI-301].

The autolyzing culture of Corynebacterium species VSTI-301 producing the synthesis of ATP from exogenous adenine was found to contain enzyme systems, which phosphorylate AMP into ADP and ADP into ATP in the presence of pyrophosphate. The optimal conditions for manifestation of activities of both systems in a cell-free extract were determined. One of the enzymes, i. e. pyrophosphate : ADP phosphotransferase, was isolated and purified 76-fold.
