Question

The ____ protein binds arabinose (and other simple sugars) and then interacts with the portion of VirA exposed in the periplasm to increase its affinity for acetosyringone. (In your answer include the full name of the protein: for example ChvX or VirX,

Answer 1

Answer: ChvE.

Basically, acetosyringone, induces transcription o virulence gene expression in agrobacterium tumerfaciens via VirA proteins

.Monosacharides e.g Arabinose had been shown to induce this transcription not only through the VirA proteins,but also through VirE. Protein.Therefore thre VirA and ChvE forms a separate sugar-mediated regulatory pathway for virulent gene expression in Agro bacterium tumerfaciens.

ChvE, is a chromosomes encoded binding protein in the periplasma of agrobacterium cells. It function in stimulating chemotaxis in the bacteium for movement towards Arabinose sugar.This promotes sugar Uttilization and therefore virulence gene expression in the agrobacterium.

Therefore ChvE is the answer
