Figure 3.
FIGURE 3. Representation of the four EF-hand motifs (EF-1, EF-2, EF-3, EF-4). a, calcium-bound EF-hand motifs (EF-3 and EF-4). Calcium ions and water molecules are represented as yellow and red balls, respectively. An omit map, contoured at the 7 level around each calcium ion, is superimposed. Amino acid residues involved in the calcium coordination are shown. b, calcium-unbound EF-hand motifs (EF-1 and EF-2). Non-covalent interactions within EF-hands are represented as dotted lines. In EF-2, residues forming the hydrophobic core are also shown.
