Chemical shift assignments and secondary structure prediction of the phosphorelay protein VanU from Vibrio anguillarum.

Abstract

Vibrio anguillarum is a biofilm forming Gram-negative bacterium that survives prolonged periods in seawater and causes vibriosis in marine life. A quorum-sensing signal transduction pathway initiates biofilm formation in response to environmental stresses. The phosphotransferase protein VanU is the focal point of the quorum-sensing pathway and facilitates the regulation between independent phosphorelay systems that activate or repress biofilm formation. Here we report the (1)H, (13)C, and (15)N backbone and side chain resonance assignments and secondary structure prediction for VanU from V. anguillarum.
