RESUMO
Dipeptidyl aminopeptidase BII from Pseudoxanthomonas mexicana WO24 (DAP BII) is able to cleave a variety of dipeptides from the amino-terminus of substrate peptides. For crystallographic studies, DAP BII was overproduced in Escherichia coli, purified and crystallized using the hanging-drop vapour-diffusion method. X-ray diffraction data to 2.3 Å resolution were collected using an orthorhombic crystal form belonging to space group P2(1)2(1)2(1), with unit-cell parameters a = 76.55, b = 130.86, c = 170.87 Å. Structural analysis by the multi-wavelength anomalous diffraction method is in progress.
