Outline of Final Research Achievements

High resolution crystal structure was achieved by the protein stabilization and crystallization in the space and depicted two auto-inhibition mechanisms. (1) The n-σ* interaction of Cys218 with Gly145 occluded the ATP site. (2) The C-terminal extension bound to the N-terminal region of the adjacent molecules and worked as a negative regulator. A synthesized C-terminal region peptide moderately attenuated the enzyme activity.
