Structure of KpHpxA. (a) KpHpxA protomer. (b) Hexameric structure of KpHpxA seen in the crystals and confirmed by size exclusion chromatography. (c) Topology diagram of KpHpxA. Helixes are shown as blue cylinders and strands as green arrows. The numbers correspond to the residue numbers of the first and last amino acid of each secondary structure element. The N and C termini are marked with an N and C, respectively.
