Abstract
PNGase F is an amidase that hydrolyzes the beta-aspartylglucosylamine bond of asparagine-linked glycopeptides and glycoproteins. Enzymatic a ctivity of PNGase F requires the recognition of both the peptide and t he carbohydrate moiety. Crystals of PNGase F were grown by sitting dro p vapor diffusion methods at 10 degrees C. The precipitating buffer co ntains both polyethylene glycol 3350 and (NH4)(2)SO4 in sodium acetate buffer at pH 4.3. The crystals belong to the orthorhombic space group C222(1) with cell dimensions: a = 87.16 Angstrom, b = 125.10 Angstrom , c = 79.33 Angstrom and diffract to 1.8 Angstrom resolution.
