Extensive homologies between lectins from non‐leguminous plants

Sequence studies were performed on lectins from two non‐leguminous plants: rice and nettle. Extensive homologies were found between these two proteins and wheat germ agglutinin in support of the conservation of lectin sequences among non‐leguminous plants. The number and positions of the cysteine residues were particularly well conserved suggesting a similar folding of the polypeptide chains.
