Computational and Experimental Analysis of the Secretome of Methylococcus capsulatus (Bath)

Expression of individual copies of Methylococcus capsulatus bath particulate methane monooxygenase genes.

The expression of the two gene clusters encoding the particulate methane monooxygenase (pMMO) in Methylococcus capsulatus Bath was assessed by analysis of transcripts and by use of chromosomal gene fusions. The results suggest that the two clusters are functionally redundant but that relative expression alters depending on the copper levels available for growth.

Towards understanding of copper dependent regulation of soluble methane monooxygenase in Methylococcus capsulatus (Bath)

The Soil Bacterium Methylococcus capsulatus Bath Interacts with Human Dendritic Cells to Modulate Immune Function

The prevalence of inflammatory bowel disease (IBD) has increased in Western countries during the course of the twentieth century, and is evolving to be a global disease. Recently we showed that a bacterial meal of a non-commensal, non-pathogenic methanotrophic soil bacterium, Methylococcus capsulatus Bath prevents experimentally induced colitis in a murine model of IBD. The mechanism behind the...

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

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...

Structure and Protein–Protein Interactions of Methanol Dehydrogenase from Methylococcus capsulatus (Bath)

In the initial steps of their metabolic pathway, methanotrophic bacteria oxidize methane to methanol with methane monooxygenases (MMOs) and methanol to formaldehyde with methanol dehydrogenases (MDHs). Several lines of evidence suggest that the membrane-bound or particulate MMO (pMMO) and MDH interact to form a metabolic supercomplex. To further investigate the possible existence of such a supe...
