2QR7: 2.0a X-Ray Structure Of C-Terminal Kinase Domain Of P90 Ribosomal S6 Kinase 2: Se-Met Derivative

Abstract
The X-ray structure at 2.0-A resolution of the p90 ribosomal S6 kinase 2 C-terminal kinase domain revealed a C-terminal autoinhibitory alphaL-helix that was embedded in the kinase scaffold and determines the inactive kinase conformation. We suggest a mechanism of activation through displacement of the alphaL-helix and rearrangement of the conserved residue Glu500, as well as the reorganization of the T-loop into the active conformation.
