Definitions related to phytohemagglutinins:
  • A class of lectins, found in beans, with hemagglutination properties. Phytohemagglutinin binds to complex oligosaccharides containing galactose, N-acetylglucosamine and mannose, causing agglutination of most mammalian red blood cell types. It induces mitosis and affects cell membrane permeability, thereby facilitating protein transport.
