title: An ultracentrifuge study on the self-association of glucose dehydrogenase from Bacillus megaterium.
abstract: The self-association of glucose dehydrogenase (beta-D-glucose:NAD(P) 1-oxidoreductase, EC 1.1.1.47) from Bacillus megaterium was studied by analytical ultracentrifugation. The pH and composition of the buffer used were such that, owing to a reversible partial dissociation of the tetrameric enzyme, enzyme activity was reduced. It was found that under these conditions the protein exists in a monomer/dimer/tetramer association equilibrium.
