Characterization of the {alpha}-helix region in domain 3 of the haemolytic lectin CEL-III: implications for self-oligomerization and haemolytic processes.

Abstract excerpt

CEL-III is a haemolytic lectin, which has two beta-trefoil domains (domains 1 and 2) and a beta-sheet-rich domain (domain 3). In domain 3 (residues 284-432), there is a hydrophobic region containing two alpha-helices (H8 and H9, residues 317-357) and a loop between them, in which alternate hydrophobic residues, especially Val residues, are present. To elucidate the role of the alpha-helix region in the haemolytic...
