a Superimposition of active site structural elements of oxidised FdhF (PDB-ID: 1fdo [https://doi.org/10.2210/pdb1FDO/pdb], transparent white) with those of the as isolated RcFDH active site (red). The map of the as isolated structure is shown as grey mesh. b Proposed hydrophilic (pink) and hydrophobic (cyan) tunnels in RcFDH. FdsA (red) and FdsD (gold) subunits are depicted as pipes and planks with Arg587, bis-MGD and cluster A1 shown as sticks.
