Acta Crystallogr.,Sect.F, 71:1429-1436, 2015 Cited by PubMed Abstract: CGL is a 150 amino-acid residue lectin that was originally isolated from the sea mussel Crenomytilus grayanus. It is specific for binding GalNAc/Gal-containing carbohydrate moieties and in general does not share sequence homology with other known galectins or lectins. Since CGL displays antibacterial, antifungal and antiviral activities, and interacts with high affinity with mucin-type receptors, which are abundant on some cancer cells, knowledge of its structure is of significant interest. Conditions have been established for the expression, purification and crystallization of a recombinant variant of CGL. The crystal structure of recombinant CGL was determined and refined at a resolution of 2.12 Å. The amino-acid sequence of CGL contains three homologous regions (73% similarity) and the folded protein has a β-trefoil topology. Structural comparison of CGL with the closely related lectin MytiLec allowed description of the glycan-binding pockets.
