Lectins are carbohydrate-binding proteins involved in diverse biological processes and with increasing relevance in biotechnological applications. In this study we report the structural characterization of a lectin from the marine red alga Amansia multifida (AML). Mass spectrometry analysis revealed two major isoforms with molecular masses of 28,388 Da and 28,661 Da. The primary structure of a lectin with a molecular weight of...
