Fig. 10From: Modeling of interaction between cytochrome c and the WD domains of Apaf-1: bifurcated salt bridges underlying apoptosome assemblyConservation of negatively charged residues in the sequences of Apaf-1 homologs. The numeration of residues corresponds to the human Apaf-1. Sequence logos were generated with WebLogo [89] from multiple alignments of 22 sequences from group I, which included Chordates (Vertebrates and Cephalochordates), and 15 sequences from group II (Hemichordates, Echinoderms, Platyhelminthes, Cnidaria, Arthropods, and Placozoa). Each position in the logo corresponds to a position in the alignment while the size of letters in the position represents the relative frequency of corresponding amino acid in this positionBack to article page
