Antinutritional properties of plant lectins
Toxicon, 2004Lectins are carbohydrate binding (glyco)proteins which are ubiquitous in nature. In plants, they are distributed in various families and hence ingested daily in appreciable amounts by both humans and animals. One of the most nutritionally important features of plant lectins is their ability to survive digestion by the gastrointestinal tract of ...

General Pharmacology: The Vascular System, 1992
This volume surveys the chemistry, biochemistry, biosynthesis, metabolism and pharmacological properties of lectins. Lectins, which are most commonly found in plants, are widespread natural products with striking biological activities. Their specific ability to recognise and bind to simple or complex saccharides facilitates their role as effective ...

Nucleocytoplasmic plant lectins
Biochimica et Biophysica Acta (BBA) - General Subjects, 2010During the last decade it was unambiguously shown that plants synthesize minute amounts of carbohydrate-binding proteins upon exposure to stress situations like drought, high salt, hormone treatment, pathogen attack or insect herbivory. In contrast to the 'classical' plant lectins, which are typically found in storage vacuoles or in the extracellular ...

Peer Review, 2023
Lectins are involved in a range of biological mechanisms related to recognition and binding to carbohydrates. This ability is possible due to the presence of a carbohydrate recognition domain with capacity to differentiate between various oligosaccharides without modify the molecules which it binds.

Antitumor effect of plant lectins
Natural Toxins, 1997AbstractThis review examines the literature data concerning the biological activity of plant lectins. Numerous studies have reported that these substances possess toxic, cytotoxic, antitumor, and anticarcinogenic properties. A brief description of the biological properties of plant lectins, as well as the effect of plant lectins on normal and malignant

Subunit assembly of plant lectins
Current Opinion in Structural Biology, 2007Lectins are a structurally diverse group of carbohydrate recognizing proteins that are involved in various biological processes and exhibit substantial structural diversity. Interestingly, in spite of having varied carbohydrate-binding specificities, they show modest variation in their secondary and tertiary structure.

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.
