P. gingivalis prolyl tripeptidyl aminopeptidase has been crystallized by the vapour-diffusion method. Diffraction data have been collected and processed to 2.1 Å resolution. A recombinant form of prolyl tripeptidyl aminopeptidase from Porphyromonas gingivalis has been crystallized by the hanging-drop vapour-diffusion method using potassium sodium tartrate as a precipitating agent. The crystals belong to the hexagonal space group P6{sub 3}22, with unit-cell parameters a = b = 149.4, c = 159.7 Å. The crystals are most likely to contain one subunit of a dimer in the asymmetric unit, with a V{sub M} value of 3.14 Å{sup 3} Da{sup −1}. Diffraction data were collected to 2.1 Å resolution using synchrotron radiation at the BL5 station of the Photon Factory.
