Ribitol dehydrogenase has been purified to homogeneity from several strains of Klebsiella aerogenes. One strain yields 3–6g of pure enzyme from 1kg of cells. The enzyme is a tetramer of four subunits, mol.wt. 27000. Preliminary studies of the activity of the enzyme are reported. Peptide ‘maps’ together with the amino acid composition indicate that the subunits are identical.
