Two-component systems in Arabidopsis thaliana--A structural view

Abstract

Plants respond to outside stimuli by initiating signaling cascades that regulate gene expression. Little structural information is available on the signaling proteins that are part of the two-component systems of plants, and how changes in phosphorylation translate into alterations of three-dimensional structures and changes in recognition domains remains largely mysterious. Our work is on deciphering aspects of these systems through the crystallization and structural analysis of two-component system proteins in Arabidopsis thaliana.
