The lectin from Moluccella laevis seeds agglutinates specifically blood-type-A and -N erythrocytes, and both activities are inhibited by micromolar concentrations of N-acetyl-D-galactosamine. The lectin consists of three subunits: a 67 kDa heterodimer, made up of two S-S-linked polypeptides of 28
This work provides evidence of a physical instance in which some proteins that are usually inactivated under strong chaotropic conditions may become fully resistant through the occupancy of their binding sites with suitable ligands. In this regard, we found that Moluccella laevis lectin remains
