Table 6. Unit-cell parameters for 14 isomorphous atomic resolution structures of HCA II.

The structures all have the symmetry of space group P2₁. Statistics are based on values taken from the PDB files. Δ = value − average. Values in parentheses are those from the published papers where these differ from the values in the deposited files. All unit-cell parameters were determined at 100 K.
