Abstract: | Ricinus communis agglutinin (RCA) B chain, in contrast to ricin B chain, contains fucose. Since both RCA and ricin B chain lose two oligosaccharide side chains when treated with β-endo N-acetylglucosaminidase H, it is proposed that fucose is present on a third oligosaccharide. This third oligosaccharide is not present on the ricin B chain and accounts for the larger relative molecular mass of the RCA B chain.Ricinus communis agglutininRicinB chainFucose |
