Function
[LECA_DIOVI] D-mannose/D-glucose-binding lectin. Has anti-inflammatory activity in rats. Induces histamine release in mast cells from hamster and rat. Induces lymphocyte proliferation and IFNG production. Shows toxicity against the aquatic snail B.glabrata at concentrations higher than 20 ug/ml.[REFERENCE:1][1] [2] [3] [4] [5] [6] [7]
Publication Abstract from PubMed
The lectin of Dioclea virgata (DvirL), both native and complexed with X-man, was submitted to X-ray diffraction analysis and the crystal structure was compared to that of other Diocleinae lectins in order to better understand differences in biological properties, especially with regard to the ability of lectins to induce nitric oxide (NO) production. An association was observed between the volume of the carbohydrate recognition domain (CRD), the ability to induce NO production and the relative positions of Tyr12, Arg228 and Leu99. Thus, differences in biological activity induced by Diocleinae lectins are related to the configuration of amino acid residues in the carbohydrate binding site and to the structural conformation of subsequent regions capable of influencing site-ligand interactions. In conclusion, the ability of Diocleinae lectins to induce NO production depends on CRD configuration.
