CRYSTAL STRUCTURE OF A BINARY COMPLEX OF PROTEIN KINASE CK2 (ALPHA-SUBUNIT) AND MG-GMPPNP
Overview
The structures of the catalytic subunit of protein kinase CK2 from Zea mays complexed with Mg2+ and with analogs of ATP or GTP were determined to 2.2 A resolution. Unlike most other protein kinases, CK2 from various sources shows 'dual-cosubstrate specificity', that is, the ability to efficiently use either ATP or GTP as a cosubstrate. The structures of these complexes demonstrate that water molecules are critical to switch the active site of CK2 from an ATP- to a GTP-compatible state. An understanding of the structural basis of dual-cosubstrate specificity may help in the design of drugs that target CK2 or other kinases with this property.
