Fig. 1. Structure of the clamp-loader complex. (A) Two
views of the structure of the ATP S complex. The A
subunit is , which is primarily
responsible for opening the clamp. The ATP-binding
subunits, , are labeled B-D. The
E subunit is '. (B) Schematic
diagram showing a suggested mechanism for clamp binding by the
clamp-loader complex. Illustrations of protein structures were
generated by using PYMOL (43).
