Figure 6From: Structural basis of regulation and substrate specificity of protein kinase CK2 deduced from the modeling of protein-protein interactionsStructural model of auto phosphorylation of one holoenzyme (blue catalytic subunit and pink β-subunit) by another holoenzyme (green catalytic subunit and brown β-subunit. The arrows indicate the β-subunits that are poised to undergo phosphorylation in this reciprocative trans autophosphorylation model. Figure generated using SETOR [44].Back to article page
