Ankyrin repeats in context with human population variation
Fig 2
(A) Trio of ARs from a designed ankyrin repeat protein [14] (PDB: 5MA3). These three ARs display the main interactions responsible for the correct packing of the ARD. Hydrogen bond interactions are depicted by blue lines whereas hydrophobic ones are depicted in orange; (B) Hydrophobic network formed by Leu6 in the hydrophobic core of the domain; (C) Hydrogen bonding network at the β-turn between positions Asp32-Gly2; (D) Inter-repeat hydrogen bonds between conserved Asn29 and Asp27; (E) Thr4 forms three hydrogen bonds with His7. Structure visualization with UCSF Chimera [7].
