1. Schematic diagram demonstrating the potential fate of methane-associated hydrogen atoms in the aerobic methanotrophy pathway.
Schematic diagram demonstrating the potential fate of methane-associated hydrogen atoms in the aerobic methanotrophy pathway. Hydrogen atoms are distinguished by color and superscript number; asterisks represent location-specific ambiguity. Potentially detectable methane-derived hydrogen atoms and carbon atoms are highlighted in orange and purple boxes, respectively. Mmo enzymes are not believed to perform reversible reactions. FDH, formate dehydrogenase; CytCox, oxidized cytochrome c; CytCred, reduced cytochrome c; MDH, methanol dehydrogenase; pMMO, particulate methane monooxygenase; sMMO, soluble methane monooxygenase.
