Banana lectin crystallography

  • Are green bananas lectin free?

    If you are on a lectin friendly diet, you are also allowed to enjoy green bananas, but not ripe bananas as they contain lectins in addition to the high amount of sugar.
    Sorghum is a great source of fiber (resistant starch) and low in lectins in comparison to barley, brown rice, quinoa, and whole wheat..

  • How do you extract lectin from bananas?

    Banana lectin (BanLec) was isolated from slightly overripe bananas (PCI 6-7) by homogenation in NaCl solution, followed by extraction in the presence of glucose, ammonium sulfate precipitation, and affinity chromatography..

  • What is the structure of a lectin?

    Lectins with galactose specificity consist of four identical protomers composed of large α-chains and small β-chains containing a single sugar binding site.
    X-ray diffraction analysis showed that .

    1. D structure of jacalin (Sankaranarayanan et al
      2. ., 1996) is composed of three fold symmetric β-prism.

  • What lectins are in bananas?

    The banana lectin, BanLec, which belongs to the monocots, is rather distant from the dicot groups.
    Molecular modelling..

  • Lectins are proteins found in a diversity of organisms.
    They possess the ability to agglutinate erythrocytes with known carbohydrate specificity since they have at least one non-catalytic domain that binds reversibly to specific monosaccharides or oligosaccharides.
  • The structure of Banlec has a beta-prism-I fold, similar to other family members, but differs from them in its mode of sugar binding.
Banlec belongs to a subgroup of this family that binds to glucose/mannose, but is unique in recognizing internal alpha1,3 linkages as well as beta1,3 linkages 

Is recombinant Banana lectin isoform a useful tool for glycoproteomics?

A novel recombinantly produced banana lectin isoform is a valuable tool for glycoproteomics and a potent modulator of the proliferation response in CD3+, CD4+, and CD8+ populations of human PBMCs

Int

Is there lectin in bananas?

One of the predominant proteins in the pulp of ripe bananas (Musa acuminata L

) and plantains (Musa spp ) has been identified as a lectin

What are the biological properties of lectins?

Lectins are carbohydrate-binding proteins and their biological properties include cell-cell interactions
