Crystal structure of Dioclea violacea seed lectin

Structural highlights

2gdf is a 4 chain structure with sequence from Macropsychanthus violaceus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	X-ray diffraction, Resolution 2.4Å
Ligands:	CA, MN
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

LECA_DIOGR D-mannose/D-glucose-binding lectin. Has anti-inflammatory activity in rats. Induces histamine release in mast cells from rat. Induces lymphocyte proliferation and IFNG production. Shows toxicity against the aquatic snail B.glabrata at concentrations higher than 50 ug/ml.^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Evolutionary Conservation
