title: The catalytically active form of histidinol dehydrogenase from Salmonella typhimurium.
abstract: The active-enzyme-sedimentation procedure was used to identify the catalytically competent form of histidinol dehydrogenase (EC 1.1.1.23) isolated from Salmonella typhimurium. At pH 9.4 the active species has a sedimentation coefficient S20,W of 5.4S, indicating that the dimer with a mol.wt. of approx. 83 000 is the enzymically active form.
