The D-galactoside binding lectin purified from sea urchin (Anthocidaris crassispina) eggs exists as a disulphide-linked homodimer of two subunits; the dimeric form is essential for hemagglutination activity [1]. The sea urchin egg lectin (SUEL) forms a new class of lectins that binds D-galactoside and L-rhamnose, with preference for L-rhamnose [1,2].	Domain
