  • PubMed Abstract: 

    cAMP-dependent protein kinase (cAPK), a ubiquitous protein in eukaryotic cells, is one of the simplest members of the protein kinase family. It was the first protein kinase to be crystallized and continues to serve as a biochemical and structural prototype for this family of enzymes. To further understand the conformational changes that occur in different liganded and unliganded states of cAPK, the catalytic subunit of cAPK was crystallized in the absence of peptide inhibitor.
