Predicted sequence and structure of a vegetative lectin in Pisum sativum.
We report the predicted sequence of four vegetative homologues (Blec1,2,3 and 4) of the pea seed lectin. This study indicates that, in contrast to the single-copy pea seed lectin (Kaminski et al., Plant Mol Biol 9:497-507, 1987), the pea vegetative lectin is transcribed by at least four members of a highly conserved multigene family whose members are only distantly related to the pea seed lectin at the primary amino-acid sequence level. For example, Blec1 shares only 38% amino-acid identity with the pea seed lectin. However, molecular homology modelling predicts that Blec1 probably forms a similar tertiary structure to the pea seed lectin.
