Neuraminyllactose-binding hemagglutinin (IPR007876)

Short name: NeuraminylLac-bd_hemagglutn

Overlapping homologous superfamilies

Family relationships



This family is comprised of several flagellar sheath adhesin proteins also called neuraminyllactose-binding haemagglutinin precursor (NLBH or HpaA) or N-acetylneuraminyllactose-binding fibrillar haemagglutinin receptor-binding subunits. NLBH is found exclusively in Helicobacter which are gut colonising bacteria and bind to sialic acid rich macromolecules present on the gastric epithelium [PMID: 11855744]. The sialic acid-sensitive agglutination of erythrocytes by certain strains of Helicobacter pylori has been attributed to the NLBH protein [PMID: 7592366].
