PKR kinase domain- eIF2alpha- AMP-PNP complex.
The structure was published by Dar, A.C., Dever, T.E., and Sicheri, F., in 2005 in a paper entitled "Higher-Order Substrate Recognition of eIF2alpha by the RNA-Dependent Protein Kinase PKR." (abstract).
This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2005.
The experimental data on which the structure is based was also deposited.
