Figure 2

Crystal structure of RihA bound to DAPIR. A) The RihA monomer, with α-helices coloured brown, β-strands blue, and loop regions in cyan. The active site Ca2+ ion is shown as a yellow sphere, and the DAPIR molecule as sticks coloured according to atom type. B) The RihA tetramer, as observed in the asymmetric unit of the RihA-DAPIR complex crystals.
