CRPs five promoter structures are folded into two anti-parallel β-sheets with flattened jellyroll topologies. Each promoter contains a recognition face with a phosphocholine binding site consisting of two coordinated calcium ions adjacent to a hydrophobic pocket. | CRPs five promoter structures are folded into two anti-parallel β-sheets with flattened jellyroll topologies.

+ | The co-crystallized structure of CRP with phosphocholine suggest that Phe-66 and Glu-81 are two key residues that mediate binding between phosphocholine and CRP. More specifically, Phe-66 provides hydrophobic interactions with the methyl groups of phosphocholine. Similarly, Glu-81 is found on the opposite end of the pocket where it interacts well with the positively charged choline nitrogen. Present on the opposite face of the pentamer is the effector face, where the presumed C1q and Fcγ receptors bind |
