Abstract:
A new procedure for the purification of nucleoside diphosphate kinase from human erythrocytes is described. The enzyme (105 kDa by gel filtration) is made-up of two different kinds of subunits (19.0 and 20.5 kDa), both displaying enzymatic activity. The probable subunit structure of the enzyme is hexameric. The discrepancies related to earlier work are discussed.
