Localization of Periplasmic Redox Proteins of Alcaligenes faecalis by a Modified General Method for Fractionating Gram-Negative Bacteria

A lysozyme-osmotic shock method is described for fractionation of Alcaligenes faecalis which uses glucose to adjust osmotic strength and multiple osmotic shocks. During phenylethylamine-dependent growth, aromatic amine dehydrogenase, azurin, and a single cytochrome c were localized in the periplasm. Their induction patterns are different from those for the related quinoprotein methylamine dehydrogenase and its associated redox proteins.
