Browsing Pathways

The pathway can start in various spots. First step in this case starts with NADH interacting with a menaquinone oxidoreductase resulting in the release of a NADH and a hydrogen Ion, at the same time in the inner membrane a menaquinone interacts with 2 electrons and 2 hydrogen ions thus releasing a menaquinol. This allows for 4 hydrogen ions to be transferred from the cytosol to the periplasmic space. The menaquinol then interacts with a trimethylamine N-oxide reductase resulting in the release of 2 hydrogen ion and 2 electrons. At the same time trimethylamine N-oxide and 3 hydrogen ions interact with the enzyme trimethylamine N-oxide reductase resulting in the release of a trimethylamine and a water molecule, this reaction happening in the periplasmic space. The second set of reactions starts with a hydrogen interacting with a menaquinone oxidoreductase resulting in the release of two electrons being released into the inner membrane which then react with with 2 hydrogen ion and a menaquinone to produce a menaquinol. This menaquinol then reacts with a trimethylamine N-oxide reductase following the same steps as mentioned before. The third set of reactions starts with with formate interacting with a formate dehydrogenase-O resulting in a release of carbon dioxide and a hydrogen ion, this releases 2 electrons that interact with a menaquinone and two hydrogen ions. This releases a menaquinol which then reacts with a trimethylamine N-oxide reductase following the same steps as mentioned before
