title: Gold helps bacteria to oxidize methane.
abstract: With the use of labeled methane-14C and by chromatographic analysis it was shown that gold-containing protein ("Au-protein"), isolated from goldphilic Micrococcus luteus bacteria, catalyzes the oxidation of methane to methanol in the system also containing NADH, air, K(3)Fe(CN)(6) and Tris-HCl buffer. Presumably Au-protein helps bacteria to survive when usual sources of carbon and energy are scarce.
