ISLAMABAD-Advanced X-ray techniques yield insights into a bacterial enzyme that turns methane gas into liquid fuel.Scientists have determined the structure of a unique enzyme, produced by a species of methane-eating bacteria, that converts the greenhouse gas into methanol \u2013 a highly versatile liquid fuel and industrial product ingredient.Their new study, published in the Journal of the American Chemical Society, is the first to report the structure of the enzyme, called soluble methane monooxygenase (sMMO), at room temperature in both its reduced and oxidized forms. This detailed structural information will help researchers design efficient catalysts for industrial methane to methanol conversion processes.Studying such enzymes by traditional X-ray methods typically gives incorrect results because of radiation damage. By using XFEL, the researchers were able to get accurate structural information in the two oxidation states.Bacteria that metabolize methane (methanotrophs) are found in soil and aquatic environments with little to no oxygen. In these anaerobic habitats, the bacteria play a critical role as carbon recyclers; they convert methane (CH4) into more useful molecules that they and other organisms depend on.<\/p>\n","protected":false},"excerpt":{"rendered":"
