The predicted tetrahedral tetrameric assembly of M. tuberculosis HsaD in solution. The molecular assembly was predicted using the Protein Interfaces, Surfaces and Assemblies service (PISA) at the European Bioinformatics Institute (http://www.ebi.ac.uk/msd-srv/prot_int/pistart.html; Krissinel & Henrick, 2007 ▶). The assembly may be described as a dimer of dimers in which the monomers coloured green and yellow form one dimer and the monomers coloured blue and magenta form the second dimer. The view in (b) was generated by rotating view (a) by 180° around the y axis. The figure was prepared with CCP4mg.
