Abstract excerpt

Agrobacterium tumefaciens is a plant pathogen that utilizes a type IV secretion system (T4SS) to transfer DNA and effector proteins into host cells. In this study we discovered that an alpha-crystallin type small heat-shock protein (alpha-Hsp), HspL, is a molecular chaperone for VirB8, a T4SS assembly factor. HspL is a typical alpha-Hsp capable of protecting the heat-labile model substrate citrate synthase from...
