The Ti Plasmid of Agrobacterium tumefaciens Harbors an attM-Paralogous Gene, aiiB, Also Encoding N-Acyl Homoserine Lactonase Activity

Résumé

The Agrobacterium tumefaciens C58 genome contains three putative N-acyl homoserine lactone (acyl-HSL) hydrolases, which are closely related to the lactonase AiiA of Bacillus. When expressed in Escherichia coli, two of the putative acyl-HSL hydrolases, ARM and Mill, conferred the ability to degrade acyl-HSLs on the host. In Erwinia strain 6276, the lactonases reduced the endogenous acyl-HSL level and the bacterial virulence in planta.
