Figure 3. (a) The B factors of the centrin and peptide C^α
atoms in the complex ΔN25-HsCen2/P17-XPC, plotted against the
residue number. Data for the two centrin and two peptide
molecules in the crystallographic asymmetric unit (black and
red) are compared with the corresponding factors in the
structure by Thompson et al.^18 (blue and green). The helical
fragments in the protein are indicated by the shaded areas. The
empty and filled green circles indicate the free and bound Ca^2+
sites, respectively. (b) The Ramachadran plot of the complex
dimer; 95.5% and 4.5% of the residues were found in the most
favored and additional allowed regions, respectively.
