Enzyme Information
| 1.17.5.3 |
Formate dehydrogenase-N.
based on mapping to UniProt P24183
Formate + a quinone = CO(2) + a quinol.
-!- Formate dehydrogenase-N oxidizes formate in the periplasm, transferring electrons via the menaquinone pool in the cytoplasmic membrane to a dissimilatory nitrate reductase (EC 1.7.5.1), which transfers electrons to nitrate in the cytoplasm. -!- The system generates proton motive force under anaerobic conditions. -!- Formerly EC 1.1.5.6.
