Abstract
New purine nucleoside 5'-phosphate (mono, di or tri) 3'(2')-diphosphates and the sodium, lithium and potassium salts thereof are elaborated by the enzymatic transfer of pyrophosphoryl group from ATP (adenosine triphosphate), dATP (deoxyadenosine triphosphate) and pppApp (adenosine 5'-triphosphate 3'(2')diphosphate) to specified 5'-purine nucleotides, and a new nucleotide pyrophosphotransferase used for this enzyme reaction is produced by actinomycetes and other microorganisms and recovered from the culture filtrate and mycelium by the conventional methods for recovering enzymes.
