title: Crystallization of a complex between an elastase-specific inhibitor elafin and porcine pancreatic elastase.
abstract: A complex between synthetic elafin, an elastase-specific inhibitor, and porcine pancreatic elastase was crystallized using 2-methyl-2,4-pentanediol as precipitant. The crystals belong to the monoclinic space group P2(1) with cell parameters a = 37.91 A, b = 73.32 A, c = 48.92 A, beta = 105.4 degrees, and one complex molecule in the asymmetric unit. The crystals diffract X-rays to 1.9 A resolution and are suitable for crystallographic structure analysis.
