Cation binding on extralong MnP. (a, b) Anomalous difference electron-density maps showing two Mn2+ (a) and three Cd2+ (b) ions in the proximity of haem (and six acidic residues) in the crystal structures of metal complexes of extralong MnP6 from C. subvermispora (PDB entries 4czp
and 4czr
, respectively). |
