Crystallization (Commentary)

Crystallization (Comment) Organism
sitting-drop vapor diffusion technique. The best crystals are obtained when using 100 mM citrate (pH 5.5) and 17.5% polyethylene glycol 400 or 100 mM sodium acetate (pH 4.5), 50 mM CdCl2 and 28% polyethylene glycol 400 as reservoir solutions. Crystal structures of inactive 3-mers and active 12-mers of DegQ reveal molecular details of elements of a conserved allosteric activation cascade that defines distinct protease ON and OFF states Legionella pneumophila subsp. pneumophila

Subunits

Subunits Comment Organism
More DegQLp forms predominantly trimers in the substrate-free state. In vitro, oligomerization is influenced by the pH of the protein solution and the presence of co-purified peptides binding to the PDZ1 and/or protease site. Misfolded proteins or peptides promote the assembly of protease active 12- or 24-mers the assembly of proteolytically active Legionella pneumophila subsp. pneumophila
