X-RAY CRYSTAL STRUCTURE OF C2S HUMAN GALECTIN-1 COMPLEXED WITH GALACTOSE
Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1GZW PDB ENTRY 1GZW
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 5.6 CRYSTALS WERE OBTAINED IN SITTING DROPS BY MIXING EQUAL VOLUMES OF THE PROTEIN SOLUTION (10 MG/ML) AND THE PRECIPITATING BUFFER (2M AMMONIUM SULPHATE AND 1% BETA-MERCAPTO ETHANOL, PH 5.6). THE GALACTOSE COMPLEX WAS OBTAINED BY SOAKING C2S CRYSTALS FOR 72H IN THE MOTHER LIQUOR SUPPLEMENTED WITH 10 MM OF GALACTOSE
