This is the C-terminal domain of the alpha chain found in Marasmius Oreades lectin protein (MOA) which binds specifically with Gal.alpha(1,3)Gal-containing sugar epitopes. The enzymatic activity of the MOA may be associated with this domain. The domain has an alpha/beta-fold, which features a central six-stranded, mostly anti-parallel, beta-sheet flanked by three alpha-helices, and a short two-stranded beta-sheet [1].	Domain
