The list is shown below (Table ): Protein Kinase (IPR000719) is a protein kinase that contains numerous conserved regions in its catalytic domain. There is a group of glycine-rich residues close to the lysine residue at the N-terminus of the catalytic domain that helps ATP bind. A conserved aspartate residue in the central region of the catalytic domain significantly influences the catalytic activity of the enzyme.
