Results: The x-ray structure of the FIBCD1 FReD reveals how FIBCD1 binds acetylated and sulfated molecules. Conclusion: FReD domains combine versatility with conservation to recognize their targets. Significance: The structure suggests how FIBCD1 binds acetylated pathogen-associated molecular patterns (PAMPS) and endogenous glycosaminoglycans. The high resolution crystal structures of a recombinant fragment in the C-terminal fibrinogen-like recognition domain of FIBCD1, a vertebrate receptor that binds chitin, have been determined. The overall tetrameric structure shows similarity in structure and aggregation for the horseshoe crab innate immune protein tachylectin 5A. The higher affinity ligand N-acetylmannosamine (ManNAc) binds in the S1 internet site, predominantly by means of the acetyl group with the oxygen and acetamide nitrogen hydrogenbonded for the protein and the methyl group inserted into a hydrophobic pocket. The binding with the ManNAc pyranose ring differs markedly involving the two independent subunits, but in all structures the binding in the N-acetyl group is conserved. In the native structure, a crystal contact results in one of many independent protomers binding the first GlcNAc with the Asn340 N-linked glycan on the other independent protomer. Within the ligand-bound structure this GlcNAc is replaced by the larger affinity ligand ManNAc. Moreover, a sulfate ion has been modeled in to the electron density at a place similar towards the S3 binding web-site in L-ficolin, whereas inside the native structure an acetate ion has been placed in the S1 N-acetyl binding web page, plus a sulfate ion has been placed adjacent to this web-site. These ion binding websites are ideally placed to get the N-acetyl and sulfate groups of sulfated.
