Table 3. Iron–iron distances (in Å) in the T (PDB entry 2hhb), R (PDB entry 1aj9) and Hb ζ₂β^s ₂ structures.

In structures with a tetramer in the asymmetric unit, the distance is the average between two symmetry-related dimers. Similar distances were also obtained when PDB entries 2dn2 (T structure) or 1ljw (R structure) were used in the analysis.

Hemoglobin	α1β1	α1β2	α1α2	β1β2	Total
T	36.5	24.4	34.2	39.5	134.6
R	34.8	25.7	34.8	34.7	130.0
Hb ζ₂β₂ ^s, ABCD	34.9	24.6	34.1	38.7	132.6
