1DS5 - PubMed Abstract: 
The crystal structure of a complex between the catalytic alpha subunit of Zea mays CK2 and a 23-mer peptide corresponding the C-terminal sequence 181-203 of the human CK2 regulatory beta subunit has been determined at 3.16-A resolution. The complex, composed of two alpha chains and two peptides, presents a molecular twofold axis, with each peptide interacting with both alpha chains ...
