title: Detection and changes of nucleotide pyrophosphotransferase activity in cultures of Streptomyces griseus strains on solid media.
abstract: The occurrence of nucleotide pyrophosphotransferase (ATP: nucleotide 5'-phosphate pyrophosphotransferase, EC 2.7.4) and the changes in its activity were studied during differentiation in cultures of two Streptomyces griseus strains grown on the surface of a solid medium. One of the strains does not sporulate and produce nucleotide pyro photransferase in submerged culture. Nucleotide pyrophosphotransferase could be detected, though in much differing amounts, in surface cultures of both strains.
