CRYSTAL STRUCTURE OF MAP KINASE P38 COMPLEXED TO THE DOCKING SITE ON ITS NUCLEAR SUBSTRATE MEF2A
Overview
The structures of the MAP kinase p38 in complex with docking site peptides, containing a phi(A)-X-phi(B) motif, derived from substrate MEF2A and, activating enzyme MKK3b, have been solved. The peptides bind to the same, site in the C-terminal domain of the kinase, which is both outside the, active site and distinct from the "CD" domain previously implicated in, docking site interactions. Mutational analysis on the interaction of p38, with the docking sites supports the crystallographic models and has, uncovered two novel residues on the docking groove that are critical for, binding. The two peptides induce similar large conformational changes, local to the peptide binding groove. The peptides also induce unexpected, and different conformational changes in the active site, as well as, structural disorder in the phosphorylation lip.
