Ribitol dehydrogenase from Klebsiella aerogenes. Purification and subunit structure

Abstract

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.
