'''CALMODULIN/RAT CA2+/CALMODULIN DEPENDENT PROTEIN KINASE FRAGMENT'''<br />


==Overview==
==CALMODULIN/RAT CA2+/CALMODULIN DEPENDENT PROTEIN KINASE FRAGMENT==
The structure of calcium-bound calmodulin (Ca2+/CaM) complexed with a, 26-residue peptide, corresponding to the CaM-binding domain of rat, Ca2+/CaM-dependent protein kinase kinase (CaMKK), has been determined by, NMR spectroscopy. In this complex, the CaMKK peptide forms a fold, comprising an alpha-helix and a hairpin-like loop whose C-terminus folds, back on itself. The binding orientation of this CaMKK peptide by the two, CaM domains is opposite to that observed in all other CaM-target complexes, determined so far. The N- and C-terminal hydrophobic pockets of Ca2+/CaM, anchor Trp 444 and Phe 459 of the CaMKK peptide, respectively. This, 14-residue separation between two key hydrophobic groups is also unique, among previously determined CaM complexes. The present structure, represents a new and distinct class of Ca2+/CaM target recognition that, may be shared by other Ca2+/CaM-stimulated proteins.

Publication Abstract from PubMed

The structure of calcium-bound calmodulin (Ca2+/CaM) complexed with a 26-residue peptide, corresponding to the CaM-binding domain of rat Ca2+/CaM-dependent protein kinase kinase (CaMKK), has been determined by NMR spectroscopy. In this complex, the CaMKK peptide forms a fold comprising an alpha-helix and a hairpin-like loop whose C-terminus folds back on itself. The binding orientation of this CaMKK peptide by the two CaM domains is opposite to that observed in all other CaM-target complexes determined so far. The N- and C-terminal hydrophobic pockets of Ca2+/CaM anchor Trp 444 and Phe 459 of the CaMKK peptide, respectively. This 14-residue separation between two key hydrophobic groups is also unique among previously determined CaM complexes. The present structure represents a new and distinct class of Ca2+/CaM target recognition that may be shared by other Ca2+/CaM-stimulated proteins.
