This domain is hemagglutinin I (HA1) present in Physarum polycephalum. Although the physiological function of the secreted HA1 remains to be established, HA1 recognizes cell wall polysaccharides of E. coli. The beta-sandwich fold of HA1, composed of two up and down beta-sheets, is conserved among other legume lectin-like proteins. The up and down beta-sheet region is a minimal carbohydrate recognition domain [1].
