Distances between the four residues targeted for mutagenic replacement and the prosthetic groups of nitrate reductase.
| Residue | Distance to Fe/S cluster* (Å) | Distance to Proximal MGD moiety* (Å) | Distance to Distal MGD moiety* (Å) |
|---|---|---|---|
| Lys 58 | 4.3 | 3.0 | 19.8 |
| Arg 70 | 17.6 | 19.3 | 6.6 |
| Lys 130 | 30.7 | 30.2 | 22.0 |
| Arg 146 | 24.6 | 14.8 | 20.9 |
Distances are measured from the end of each side chain to the closest point of each cofactor.
