[ | [https://www.uniprot.org/uniprot/HA33C_CBCP HA33C_CBCP] Agglutinates human erythrocytes (PubMed:2205574). The hemagglutinin (HA) component of the progenitor toxin protects the structural integrity of botulinum neurotoxin; may increase internalization of the neurotoxin into the bloodstream of the host (PubMed:9421908). The hemagglutinin (HA) component is involved in binding to the upper small intestine through interactions with glycolipids and glycoproteins containing sialic acid moieties (Probable). Binds galactose or oligosaccharides with galactose at their non-reducing end (PubMed:14663070). Binds eukaryotic host mucins; binding is inhibited by N-acetyl-beta-neuraminic acid, N-acetyl-D-galactosamine, galactose, and methyl N-acetyl-beta-neuraminic acid (PubMed:18178224). Binds N-acetyl-beta-neuraminic acid, N-acetyl-D-galactosamine and galactose (but not glucose) via 2 sites (PubMed:18178224, PubMed:21640703).<ref>PMID:14663070</ref> <ref>PMID:18178224</ref> <ref>PMID:21640703</ref> <ref>PMID:2205574</ref> <ref>PMID:9421908</ref> <ref>PMID:9421908</ref> | ||
