RT   "A lectin and a lectin-related protein are the two most prominent proteins
RT   in the bark of yellow wood (Cladrastis lutea).";
RL   Plant Mol. Biol. 29:579-598(1995).
CC   -!- FUNCTION: Mannose/glucose binding bark lectin.
CC   -!- FUNCTION: Bark lectins are storage proteins that probably maintain
CC       stocks of nitrogen during dormant period. Self-aggregatable molecules
CC       that can bind their own carbohydrate side chains. They could also play
CC       a role in the plant's defense against phytophagous invertebrates or
CC       herbivorous higher animals.
CC   -!- SUBUNIT: Homotetramer.
CC   -!- MISCELLANEOUS: Binds one manganese (or another transition metal) ion
CC       and one calcium ion. The metal ions are essential for the saccharide-
CC       binding and cell-agglutinating activities (By similarity).
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the leguminous lectin family. {ECO:0000305}.
