[Properties of partially purified ATP desaminase from Actinomyces N4 antibioticus].
Three active fractions of ATP desaminase from Actinomyces N4 of type Antibioticus were obtained by gel filtration through Sephadex G-200. Some properties of each fraction were studied: effect of pH and Mg2+, substrate specificity, effect of pH on Km. The enzyme studied could be used for preparation of ITP, IDP, IMP, inosine and hypoxantine.
