Abstract

Crystals of endo-polygalacturonase from Erwinia carotovora ssp. carotovora have been grown from polyethylene glycol 6000 by the hanging-drop method. Polygalacturonase is important in the virulence of this plant pathogen. The protein crystallizes in space group C2 with unit-cell parameters a = 81.3, b = 53.0, c = 103.1 A, beta = 112.6 degrees and with a single molecule in the asymmetric unit. The crystals diffract to 1.9 A.

摘要

胡萝卜软腐欧文氏菌胡萝卜软腐亚种的内切多聚半乳糖醛酸酶晶体，通过悬滴法从聚乙二醇6000中生长出来。多聚半乳糖醛酸酶在这种植物病原体的致病性中很重要。该蛋白质在空间群C2中结晶，晶胞参数为a = 81.3、b = 53.0、c = 103.1 Å、β = 112.6°，不对称单元中有一个单分子。这些晶体的衍射分辨率达到1.9 Å。
