Intracellular localization of the particulate methane monooxygenase and methanol dehydrogenase in Methylomicrobium album BG8.

The methanotrophic bacterium Methylomicrobium album BG8 uses methane as a sole source of carbon and energy. This bacterium forms an extensive intracytoplasmic membrane. The first enzymes of the methane oxidation pathway are the membrane-bound particulate methane monooxygenase and the periplasmic methanol dehydrogenase. Immunoelectron microscopy with specific antibodies was used to localize these enzymes to the intracytoplasmic membrane.
