title: Crystallization and preliminary crystallographic analysis of porcine acylaminoacyl peptidase.
abstract: Acylaminoacyl peptidase (also known as acylamino-acid-releasing enzyme or acylpeptide hydrolase; EC 3.4.19.1) is an unusual member of the prolyl oligopeptidase family catalysing the hydrolysis of an N-acylated peptide to an acylamino acid and a peptide with a free N-terminus. Acylaminoacyl peptidase purified from porcine liver has been crystallized in mother liquor containing 0.1 M Tris-HCl pH 7.0, 10%(w/v) polyethylene glycol 8000, 50 mM MgCl2 and 1%(w/v) CHAPS using the hanging-drop vapour-diffusion technique. A full data set to 3.4 A resolution was collected at ESRF beamline ID14-4 and space group C222 was assigned, with unit-cell parameters a = 84.8, b = 421.1, c = 212.0 A and four molecules in the asymmetric unit.
