Bioenergetics of Methanococcus voltae: Possible role for a primary sodium pump in ATP formation
The mechanism of ATP formation has been characterized in a few methanogens. Evidence has been obtained in whole cells of Methanosarcina barkeri that ATP is synthesized via a chemiosmotic mechanism. Results obtained with protoplasts from Methanobacterium thermoautotrophicum also agree with a chemiosmotic mechanism of ATP synthesis. Lancaster proposed a mechanism of ATP formation in M. voltae coupled to a novel scheme of substrate level phosphorylation. The mechanisms of ATP formation in M. voltae were examined by biochemical means.
