Current Opinion in Structural Biology, 1997
Among the crystal structures of lectins determined recently, three--snowdrop lectin, jacalin and amaranthin--represent new lectin families. Their polypeptide folds share remarkably similar features and consist exclusively of beta structure. Autonomously folded beta-sheet subdomains, inter-related by a pseudothreefold symmetry, assemble to form beta ...

Cytotoxic ribosome-inactivating lectins from plants
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2004A class of heterodimeric plant proteins consisting of a carbohydrate-binding B-chain and an enzymatic A-chain which act on ribosomes to inhibit protein synthesis are amongst the most toxic substances known. The best known example of such a toxic lectin is ricin, produced by the seeds of the castor oil plant, Ricinnus communis.

History of Plant Lectin Research
2014Numerous plant species are known to express one or more lectins or proteins containing a lectin domain, enabling these proteins to select and bind specific carbohydrate structures. The group of plant lectins is quite heterogeneous since lectins differ in their molecular structure, specificity for certain carbohydrate structures, and biological ...

Plant Lectins (Phytohemagglutinins)
1976It was already recognized at the end of the last century that proteins in extracts of certain plants are able to agglutinate red blood cells. For a long time this potency has been regarded as a curiosity only. Retrospectively however, it can be said that studies with the respective proteins were landmarks in the elucitation of the basic mechanisms of ...

1981
The term lectin [Latin, legere — to pick out, choose] was coined by W. C. Boyd1 in order to call attention to a group of plant seed proteins which could distinguish among human blood groups. Boyd had discovered that extracts of the lima bean (Phaseolus lunatus) specifically agglutinated type A erythrocytes (Fig. 1).

Carbohydrate-Binding Sites of Plant Lectins
1988Lectins are a diverse group of proteins and glycoproteins that exhibit specific binding for certain carbohydrates. Proteins with this property have been described in a wide variety of taxa, ranging from bacteria (e.g. Neter 1956) to slime molds (Barondes and Haywood 1979) and lower vertebrates (Simpson et al.

Plant Lectin as defense proteins
Biotech Today : An International Journal of Biological Sciences, 2015Plant lectins are a very heterogeneous group of protein that all share one important biological property: they can recognize and bind reversibly to specific carbohydrate structures. They are one of the most important secondary metabolites in plants which are used as a defense tool against pathogens which attack plants.

Recombinant Plant Lectins and Their Mutants
2003Publisher Summary This chapter focuses on recombinant plant lectins, especially those that have been investigated by mutagenesis. Cloning and expression of plant lectins have developed into powerful tools in aiding investigations of the structure–function relationships in their lectins.

Ribosome-inactivating lectins of plants
Molecular Biology, 2006A heterogeneous group of plant proteins are capable of enzymatically inactivating ribosomes by depurination of the invariant adenine in the 28S rRNA. Some of these proteins are heterodimers, containing a lectin subunit joined to an enzymatic subunit via a disulfide bond.
