摘要: The isolation, partial purification and some properties of polynucleotide phosphorylase Azotobacter vinelandii are described. enzyme catalyzes the synthesis highly polymerized ribonucleic acid-like polynucleotides from 5′-nucleoside diphosphates with release orthophosphate. reaction requires magnesium ions is reversible. Thus, also phosphorolysis to yield corresponding diphosphates. preparation isolation a number containing one or several kinds mononucleotide units scope, mechanism significance discussed.
