Literature

Structure of benzyl T-antigen disaccharide bound to Amaranthus caudatus agglutinin.

Transue, T.R.Smith, A.K.Mo, H.Goldstein, I.J.Saper, M.A.

  • PubMed Abstract: 
  • Amaranthus caudatus agglutinin contains a novel arrangement of four beta-trefoil domains. The sugar-binding site provides specificity for the carcinoma-associated T-antigen disaccharide even when 'masked' by other sugars.
