Direct interaction between two DsrDs. (a) 2|Fo| − |Fc| neutron Fourier map around Glu50 in molecule A and Gln6 and Asp10 in molecule B. Hydrogen bonds are shown as dashed purple lines. (b) Postulated chemical structures of the three residues. Note that the carboxyl group of Glu50 is protonated, while that of Asp10 is deprotonated.
