چکیده
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.

متن کاملCrystallization and preliminary X-ray crystallographic analysis of agkicetin-C from Deinagkistrodon acutus venom.
The crystallization and preliminary crystallographic analysis of agkicetin-C, a well known platelet glycoprotein Ib (GPIb) antagonist from the venom of Deinagkistrodon acutus found in Anhui Province, China is reported. Crystals of agkicetin-C suitable for structure determination were obtained from 1.8 M ammonium sulfate, 40 mM MES pH 6.5 with 2%(v/v) PEG 400. Interestingly, low buffer concentra...
متن کاملProduction, purification, crystallization and preliminary X-ray analysis of adeno-associated virus serotype 8.
Adeno-associated viruses (AAVs) are actively being developed for clinical gene-therapy applications and the efficiencies of the vectors could be significantly improved by a detailed understanding of their viral capsid structures and the structural determinants of their tissue-transduction interactions. AAV8 is approximately 80% identical to the more widely studied AAV2, but its liver-transducti...
متن کاملPurification, crystallization and preliminary X-ray analysis of IMP-18, a class B carbapenemase from Pseudomonas aeruginosa.
Class B β-lactamases are known as metallo-β-lactamases (MBLs) and they hydrolyze most β-lactams, including carbapenems. IMP-18, an MBL cloned from Pseudomonas aeruginosa, was overexpressed, purified and crystallized by vapour diffusion for X-ray crystallographic analysis. Preliminary X-ray analysis showed that the crystal diffracted to 2.4 Å resolution and belonged to the tetragonal space group...
