Figure 2 CBD in the presence and absence of calcium. (A) In the
high resolution apo-CBD structure, no calcium was observed, and
the N-terminus residues 895 -908 adopted an -helix
conformation (colored red) in one molecule of the ASU. (B) In
the holo-CBD structure, two Ca^2+ ions were found (colored
orange), and the N-terminus residues 890 -908 continued the -sheet
on the back face of the protein. Residues N963 -N966 were not
resolved. The tyrosine-rich surface is at the left and the back
face is at the right of each molecule.
