Figure 7. Geometry around the Ca^2+-binding site in CLPs.
(A) Subunit A. (B) Subunit B. Superposition of the Ca^2+ ion
coordination site in IX/X-bp (green) with the corresponding site
in rhodocetin (blue). Glu 128A and Glu 120B of IX/X-bp are
replaced by Lys 128 in the -subunit and
Lys 124 in the -subunit,
respectively. This substitution could prevent the metal ion from
binding rhodocetin.
