FIG. 1.

Sequence alignment of DdCenB with other members of the centrin family. The four canonical EF-hand consensus motifs are shown at the top of the alignment. X, Y, Z, x, and z: residues containing oxygen in the side chains that provide five of the six coordination points for the interaction with calcium. y: residue with a carbonyl oxygen that provides the sixth coordination point. I: I, L, or V. #: hydrophobic residues. n: any residue. Identities shared by at least five of the sequences are shaded in black. Similar amino acids shared by at least four of the sequences are shaded in gray. The alignment was performed with BioEdit 7.0.5.3.
