Crystallization and preliminary crystallographic analysis of human common-type acylphosphatase.

ABSTRACT: Human acylphosphatase, an 11 kDa enzyme that catalyzes the hydrolysis of carboxyl phosphate bonds, has been studied extensively as a model system for amyloid-fibril formation. However, the structure is still not known of any isoform of human acylphosphatase. Here, the crystallization and preliminary X-ray diffraction data analysis of human common-type acylphosphatase are reported. Crystals of human common-type acylphosphatase have been grown by the sitting-drop vapour-diffusion method at 289 K using polyethylene glycol 4000 as precipitant. Diffraction data were collected to 1.45 A resolution at 100 K. The crystals belong to space group P2(1)2(1)2(1), with unit-cell parameters a = 42.58, b = 47.23, c = 57.26 A.
