Crystallization and preliminary diffraction studies of a recombinant major urinary protein

A monoclinic crystal form of a recombinant major urinary protein, (MUP) from mouse, has been obtained. MUP is a member of the lipocalin family whose biological function relates to olfaction and sexual communication. Crystals were grown by the vapour-diffusion technique against a mother liquor containing CdCl₂. Crystals belong to the monoclinic space group P2₁ with the cell parameters a = 37.14, b = 55.79, c = 37.67 Å, and β = 93.24°. The crystals diffract to beyond 1.4 Å resolution at a synchrotron beamline.
