Isolation and characterization of a second lectin (SNA-II) present in elderberry (Sambucus nigra L.) bark.
A second lectin (SNA-II) has been isolated from elderberry (Sambucus nigra L.) bark by affinity chromatography on immobilized asialo-glycophorin. This lectin is a blood group nonspecific glycoprotein containing 7.8% carbohydrate and which is rich in asparagine/aspartic acid, glutamine/glutamic acid, glycine, valine, and leucine. Gel filtration on Superose 12 gave a single symmetrical peak corre...
متن کاملFlow Lectin Affinity Chromatography–A Model with Sambucus nigra Agglutinin
The study of proteomes has become an important way to assess changes occurring in disease conditions. Nonetheless, the dominance of highly abundant serum proteins significantly complicates the discovery and analysis of low-abundant glycoproteins that may constitute potential disease biomarkers. Several techniques have been used to perform serum proteome partitioning such as affinity chromatogra...
متن کاملStructural Basis for Multiple Sugar Recognition of Jacalin-related Human ZG16p Lectin*
ZG16p is a soluble mammalian lectin, the first to be described with a Jacalin-related β-prism-fold. ZG16p has been reported to bind both to glycosaminoglycans and mannose. To determine the structural basis of the multiple sugar-binding properties, we conducted glycan microarray analyses of human ZG16p. We observed that ZG16p preferentially binds to α-mannose-terminating short glycans such as Se...
متن کاملThe structural basis of antigen-antibody recognition.
We have reviewed here the three-dimensional structure of an antigen-Fab complex as determined by X-ray crystallographic studies. The antigen is hen egg-white lysozyme (HEL), a protein whose three-dimensional structure and antigenic properties are well known. The Fab was prepared from a murine monoclonal anti-HEL antibody, IgGl,kappa, obtained by cell-hybridization techniques. The equilibrium as...
متن کاملThe Structural Basis of Antibody-Antigen Recognition
The function of antibodies (Abs) involves specific binding to antigens (Ags) and activation of other components of the immune system to fight pathogens. The six hypervariable loops within the variable domains of Abs, commonly termed complementarity determining regions (CDRs), are widely assumed to be responsible for Ag recognition, while the constant domains are believed to mediate effector act...
