Crystallization of two related lectins from the legume plant Dolichos biflorus.
The seed lectin DBL and the related stem and leaves lectin DB58 of the tropical legume Dolichos biflorus were crystallized, as well as complexes of DBL with adenine and with GalNAc(alpha1-3)[Fuc(alpha1-2)]Gal. The different crystal forms of DBL diffract to about 2.8 A, while DB58 crystals diffract to 3.3 A.
