Structural highlights
, pdb structure 3fhi[1], is shown with small lobe in gray, large lobe in tan and regulatory unit in light blue. The residues from exon 1 (labeled) from the residues which bind to the regulatory unit R (shown in ball and stick). The last three residues from exon 1 (residues # 13-15) are the only translated amino acids from first exon of pkaca that were well-crystalized in this structure. These three residues are - a second regulator/inhibitor of 'C', as well. This is also obvious from the pdb structure for the , 1atp[2].
