The contribution of Fe(II)-oxidizing bacteria to iron cycling in freshwater, groundwater, and marine environments has been widely recognized in recent years. These organisms perform extracellular electron transfer (EET), which constitutes the foundations of bioelectrochemical systems for the production of biofuels and bioenergy. It was proposed that the Gram-negative bacterium Sideroxydans lithotrophicus ES-1 oxidizes soluble ferrous Fe(II) at the surface of the cell and performs EET through the Mto redox pathway.

- Chemolithoautotrophic Fe(II)-oxidizing bacteria like Sideroxydans lithotrophicus ES-1 are key players in freshwater ecosystems and biogeochemical cycling, yet their electron transport proteins are not well-studied due to cultivation challenges.* -
- The protein Slit_2495, proposed to be involved in electron transfer, is suggested to be renamed ImoA because it shows closer evolutionary ties to NirT proteins rather than the previously assumed CymA.* -
- ImoA functions effectively to oxidize quinol pools in the inner membrane, raising important questions about the mechanisms of electron flow in the Mto pathway of S. lithotrophicus, especially concerning its directionality
Metalloproteins represent a substantial fraction of the proteome where they have an outsized contribution to enzymology. This stems from the reactivity of transition metals found in the active sites of numerous classes of enzymes that undergo redox and/or spin-state transitions. Notwithstanding, NMR structures of metalloproteins deposited in the PDB are under-represented and NMR studies exploring paramagnetic states are a minute fraction of the overall database content.
