The avian infectious bronchitis virus main protease has been crystallized; crystals diffract to 2.7 Å resolution. Infectious bronchitis virus (IBV) is the prototype of the genus Coronavirus. It causes a highly contagious disease which affects the respiratory, reproductive, neurological and renal systems of chickens, resulting great economic losses in the poultry industry worldwide. The coronavirus (CoV) main protease (M{sup pro}), which plays a pivotal role in viral gene expression and replication through a highly complex cascade involving the proteolytic processing of replicase polyproteins, is an attractive target for antiviral drug design. In this study, IBV M{sup pro} was overexpressed in Escherichia coli. Crystals suitable for X-ray crystallography have been obtained using microseeding techniques and belong to space group P6{sub 1}22. X-ray diffraction data were collected in-house to 2.7 Å resolution from a single crystal. The unit-cell parameters were a = b = 119.1, c = 270.7 Å, α = β = 90, γ = 120°. Three molecules were predicted to be present in the asymmetric unit from a calculated self-rotation function.
