Outline of Final Research Achievements

Purpose of this project is exploring the interaction between peptide hormones regulating stomatal density and their receptors at atomic resolution. First of all, we had established expression systems of some domains and fragments of the receptors using E. coli and/or BY-2. Next, we had extensively searched the adequate sample solution condition for analyzing the interaction. As the result of this screening for estimating the utility of various detergents, we fortunately found a certain condition for the experiments. We successfully measured a two-dimensional NMR spectrum of the unlabeled sample in this condition. Unfortunately, the screening to find the good sample condition took very long time, so that deeper structural analyses were not performed. However, the preliminary results obtained here seem to promote the research work in near future.
