Outline of Final Research Achievements

NMR isotope shifts caused by the proton/deuteron change were exploited to reveal the relations between the proline isomerase activity of Pin1 and the hydrogen bond network formed in the active site. The isotope shift was used to quantitatively elucidate the changes in the strength of the hydrogen bonds in the network. We made three different mutants having amino acid changes to C113 in the active site of the isomerase domain of Pin1, PPIase. In addition, C138 mutation was applied to see the distal effect on the hydrogen bond network.
Combined the results from the analyses on the different mutants made the role of the hydrogen bond network in the PPIase active site clearer.
