Table 1. Comparison of the Mössbauer parameters of the [4Fe-4S]2+ cluster in human Nfu with those of other proteins.
Organism | Protein | δ, mm/s | ΔEQ, mm/s | Ref. |
---|---|---|---|---|
Hs | Nfu | 0.47 | 1.22 | This work |
Bs | Ferredoxin | 0.42 | 1.12 | 33 |
Cv | Hi PIP | 0.43 | 1.14 | 34 |
Dg | Ferredoxin I | 0.44 | 1.17 | 35 |
Av | Ferredoxin I | 0.43 | 1.19 | 36 |

The Mössbauer spectra of [4Fe-4S]2+ clusters are generally analyzed as superpositions of overlapping quadrupole doublets. The values listed here are the weighted averages. Hs, Homo sapiens; Bs, Bacillus stearothermophilus; Cv, Chromatium vinosm; Dg, Desulfovibrio giga; Av, Azotobacter vinelandii; Hi PIP, high-potential iron protein.
