CBP is structurally homologous to saposin B. (A) Backbone structural superposition of CBP (red) and SapB (blue; chain A, PDB 1N69) from FATCAT structural alignment (p-value = 4.5 e-2). RMSD for alignment was 2.51 Å with one twist (introduced by FATCAT alignment procedure at hinge region in order to get better alignment of two structures). Side-by-side structural comparison of homodimeric CBP (B) and SapB (C) with similar orientation of N-terminal helices and four helices colored identically with disulfide bonds in orange.
