Acceptor specificity of ATP:nucleoside-5'-phosphate pyrophosphotransferase from Streptomyces adephospholyticus. Synthesis of the 3'-pyrophosphates of pyrimidine nucleotides, some oligoribonucleotides, 5'-diphosphonucleosidic coenzymes and mG-5'-ppp-5'-Am.

ATP: nucleoside-5'-phosphate pyrophosphotransferase [EC 2.7.6.4] of Streptomyces adephospholyticus synthesizes not only 3'-pyrophosphates of 5'-purine ribomononucleotides but also those of pyrimidine mononucleotides, some short oligonucleotides, a variety of 5'-diphosphonucleosidic coenzymes and mG-5'-ppp-5'-Am.
