    We determined two crystal structures of the chemokine receptor CCR2A in complex with the orthosteric antagonist MK-0812. Full-length CCR2A, stabilized by rubredoxin and a series of five mutations were resolved at 3.3 Å. An N- and C-terminally truncated CCR2A construct was crystallized in an alternate crystal form, which yielded a 2.7 Å resolution structure using serial synchrotron crystallography. Our structures provide a clear structural explanation for the observed key role of residue E291 7.39 in high-affinity binding of several orthosteric CCR2 antagonists. By combining all the structural information collected, we generated models of co-structures for the structurally diverse pyrimidine amide class of CCR2 antagonists. Even though the representative Ex15 overlays well with MK-0812, it also interacts with the non-conserved H121 3.33 , resulting in a significant selectivity over CCR5. Insights derived from this work will facilitate drug discovery efforts directed toward highly selective CCR2 antagonists with potentially superior efficacy.
