<scene name='55/555705/Subdomainviii/1'>Subdomain VIII</scene> contains the APE motif. The <scene name='55/555705/Ape/1'>glutamate in this motif (blue ball and stick) </scene>glutamate in this motif forms a salt bridge with an arginine (yellow ball and stick) in in Subdomain X1. This salt bridge is critical for forming the stable kinase core. In many protein kinases there is a phosphorylatable residue seven to ten residues upstream of the APE motif. In PKA it is a <scene name='55/555705/Phosphothreonine/1'>phosphothreonine</scene>, which forms an ionic bond with the arginine in the HRDLKPEN motif of the catalytic loop and helps to position it for catalysis.
