Figure 7. Metal binding sites in TA (a), AT (b), and AU (c). Only one metal, bound to site II, is seen in the P1 lattice for TA. AT has two metal ions bound in one subunit, with high B-factors. AU also has two metal ions bound in one subunit. One metal is bound to site I, which is also seen in other modified complexes with poor activity.
