Abstract
Pathogenicity islands are capable of excision and insertion within bacterial chromosomes. We describe a protein, Rox, that stimulates excision of the Shigella resistance locus pathogenicity island in Shigella flexneri. Sequence analysis suggests that Rox belongs to a new subfamily of recombination directionality factors, which includes proteins from P4, enterohemorrhagic Escherichia coli, and Yersinia pestis.
摘要
致病岛能够在细菌染色体中进行切除和插入。我们描述了一种蛋白质Rox，它能刺激弗氏志贺菌中志贺菌抗性位点致病岛的切除。序列分析表明，Rox属于重组方向性因子的一个新亚家族，该亚家族包括来自P4噬菌体、肠出血性大肠杆菌和鼠疫耶尔森菌的蛋白质。
