'''2.0 ANGSTROM REFINED CRYSTAL STRUCTURE OF THE CATALYTIC SUBUNIT OF CAMP-DEPENDENT PROTEIN KINASE COMPLEXED WITH A PEPTIDE INHIBITOR AND DETERGENT'''
===2.0 ANGSTROM REFINED CRYSTAL STRUCTURE OF THE CATALYTIC SUBUNIT OF CAMP-DEPENDENT PROTEIN KINASE COMPLEXED WITH A PEPTIDE INHIBITOR AND DETERGENT===




==Overview==
<!--  
. A mutant (Serl39Ala) of the mouse recombinant catalytic (C) subunit of cAMP-dependent protein kinase was co-crystallized with a peptide inhibitor, PKI(5-24), and MEGA-8 (octanoyl-N-methylglucamide) detergent. This structure was refined using all observed data (30 248 reflections) between 30 and 1.95 A resolution to an R factor of 0.186. R.m.s. deviations of bond lengths and bond angles are 0.013 A and 2.3 degrees, respectively. The final model has 3075 atoms (207 solvent) with a mean B factor of 31.9 A(2). The placement of invariant protein-kinase residues and most C:PKI(5-24) interactions were confirmed, but register errors affecting residues 55-64 and 309-339 were corrected during refinement by shifting the affected sequences toward the C terminus along the previously determined backbone path. New details of C:PKI(5-24) interactions and the Ser338 autophosphorylation site are described, and the acyl group binding site near the catalytic subunit NH(2) terminus is identified.
