Figure 2.
ArdK structure. (A) Orthogonal views of the structure of ArdK. The DD and HTH domains, the linker region and the secondary structure elements of ArdK are shown. One of the subunits is coloured in beige and the other in grey. (B) Comparison between ArdK and KorA (pdb 2N5G) solvent-accessible surface electrostatic potential. Negative potential is coloured in red and positive potential in blue from –2 kT/e to + 2 kT/e (calculated by APBS).
