The seed lectin DBL and the related stem and leaves lectin DB58 of the trop
ical legume Dolichos biflorus were crystallized, as well as complexes of DB
L with adenine and with GalNAc(alpha 1-3)[Fuc(alpha 1-2)]Gal. The different
crystal forms of DBL diffract to about 2.8 Angstrom, while DB58 crystals d
iffract to 3.3 Angstrom.
