Modelled sialylated and desialylated ACE2-Covid S protein complexes. 3D structural modeling of glycosylated ACE2 interacting with S-protein. Results from glycomics and glycoproteomics of HEPG2 cell lines were used to generate (A) fully-desialylated and (B) fully-sialylated homologs of ACE2, interacting with S-protein.
