Glutathione Metabolism in M. capsulatus

Description

Methylococcus capsulatus is an obligate, Gram-negative methanotroph. Methanotrophs are responsible for the oxidation of biologically generated methane and therefore help reduce the amount of greenhouse gas that is released to Earth s atmosphere. The conversion of methane to biomass by M. capsulatus has been exploited for large-scale commercial production of microbial proteins by fermentation. Thus, the bacterium plays major roles in global carbon cycles, and in particular, substantially reduces emissions of biologically generated methane to the atmosphere. M. capsulatus genome is highly specialized for a methanotrophic lifestyle, including redundant pathways, predicted to be involved in methanotrophy and duplicated genes for essential enzymes such as the methane monooxygenases (Ref.1).

Glutathione metabolism in M. capsulatus involves both the synthesis of Glutathione and its catabolism. [...]
