An improved assay for bacterial methane mono-oxygenase: some properties of the enzyme from Methylomonas methanica.

ABSTRACT: Extracts of Methylomonas methanica catalyse the O2-and NAD(P)H-dependent disappearance of bromomethane. The activity is unstable at 2 degrees C but is stable at --70 degrees C for several weeks. Bromomethane mono-oxygenase is particulate and is inhibited by metal-binding reagents, by compounds SKF 525A and Lilly 53325, by some metal ions and by acetylene. Evidence is presented that indicates that bromomethane mono-oxygenase is the enzyme responsible for methane oxidation in vivo.

Catalytic and Spectroscopic Properties of the Halotolerant Soluble Methane Monooxygenase Reductase from Methylomonas methanica MC09.

Project description:The soluble methane monooxygenase receives electrons from NADH via its reductase MmoC for oxidation of methane, which is itself an attractive C1 building block for a future bioeconomy. Herein, we present biochemical and spectroscopic insights into the reductase from the marine methanotroph Methylomonas methanica MC09. The presence of a flavin adenine dinucleotide (FAD) and [2Fe2S] cluster as its prosthetic group were revealed by reconstitution experiments, iron determination and electron paramagnetic resonance spectroscopy. As a true halotolerant enzyme, MmoC still showed 50 % of its specific activity at 2 M NaCl. We show that MmoC produces only trace amounts of superoxide, but mainly hydrogen peroxide during uncoupled turnover reactions. The characterization of a highly active reductase is an important step for future biotechnological applications of a halotolerant sMMO.

Purification and properties of the methane mono-oxygenase enzyme system from Methylosinus trichosporium OB3b.

Project description:1. A three-component enzyme system that catalyses the oxidation of methane to methanol has been highly purified from Methylosinus trichosporium. 2. The components are (i) a soluble CO-binding cytochrome c, (ii) a copper-containing protein and (iii) a small protein; the mol. wts. are 13 000, 47 000 and 9400 respectively. The cytochrome component cannot be replaced by similar cytochrome purified from Pseudomonas extorquens or by horse heart cytochrome c. 3. The stoicheiometry suggests a mono-oxygenase mechanism and the specific activity with methane as substrate is 6 micronmol/min per mg of protein. 4. Other substrates rapidly oxidized are ethane, n-propane, n-butane and CO. Dimethyl ether is not a substrate. 5. The purified enzyme system utilizes ascorbate or, in the presence of partially purified M. trichosporium methanol dehydrogenase, methanol as electron donor but not NADH or NADPH. 6. Activity is highly sensitive to low concentrations of a variety of chelating agents, cyanide, 2-mercaptoethanol and dithiothreitol. 7. Activity is highly pH-dependent (optimum 6.9-7.0) and no component of the enzyme is stable to freezing. 8. The soluble CO-binding cytochrome c shows oxidase acitivity and the relationship between this and the oxygenase activity is discussed.

The metal centres of particulate methane mono-oxygenase.

Project description:pMMO (particulate methane mono-oxygenase) is an integral membrane metalloenzyme that catalyses the oxidation of methane to methanol. The pMMO metal active site has not been identified, precluding detailed investigation of the reaction mechanism. Models for the metal centres proposed by various research groups have evolved as crystallographic and spectroscopic data have become available. The present review traces the evolution of these active-site models before and after the 2005 Methylococcus capsulatus (Bath) pMMO crystal structure determination.

Some properties of a soluble methane mono-oxygenase from Methylococcus capsulatus strain Bath.

Project description:Soluble extracts of Methylococcus capsulatus (Bath), obtained by centrifugation of crude extracts at 160000g for 1h, catalyse the NAD(P)H- and O2-dependent disappearance of bromomethane, and also the formation of methanol from methane. Soluble methane mono-oxygenase is not inhibited by chelating agents or by most electron-transport inhibitors, and is a multicomponent enzyme.

Steady-state kinetic analysis of soluble methane mono-oxygenase from Methylococcus capsulatus (Bath).

Project description:A steady-state kinetic analysis of purified soluble methane mono-oxygenase of Methylococcus capsulatus (Bath) was performed. The enzyme was found to follow a concerted-substitution mechanism. Methane binds to the enzyme followed by NADH, which reacts to yield reduced enzyme and NAD+. The reduced enzyme-methane complex binds O2 to give a second ternary complex, which breaks down to release water and methanol. In this way the enzyme can control the supply of electrons to the active site to coincide with the arrival of methane. Product-inhibition studies (with propylene as substrate) supported the reaction mechanism proposed. Ki values for NAD+ and propylene oxide are reported. The Km for NADH varied from 25 microM to 300 microM, depending on the nature of the hydrocarbon substrate, and thus supports the proposed reaction sequence. With methane as substrate the Km values for methane, NADH and O2 were shown to be 3 microM, 55.8 microM and 16.8 microM respectively. With propylene as substrate the Km values for propylene, NADH and O2 were 0.94 microM, 25.2 microM and 12.7-15.9 microM respectively. Methane mono-oxygenase was shown to be well adapted to the oxidation of methane compared with other straight-chain alkanes.
