    Acacia farnesiana lectin-like protein (AFAL) is a chitin-binding protein and has been classified as phytohaemagglutinin from\r\nPhaseolus vulgaris (PHA). Legume lectins are examples for structural studies, and this family of proteins shows a remarkable\r\nconservation in primary, secondary, and tertiary structures. Lectins have ability to reduce the effects of inflammation caused by\r\nphlogistic agents, such as carrageenan (CGN). This paper explains the anti-inflammatory activity of AFAL through structural\r\ncomparison with anti-inflammatory legume lectins.The AFALmodel was obtained by molecularmodeling and molecular docking\r\nwith glycan and carrageenan were performed to explain the AFAL structural behavior and biological activity. Pisum sativum lectin\r\nwas the best template for molecularmodeling.TheAFAL structuremodel is folded as a ?? sandwich.Themodel differs fromtemplate\r\nin loop regions, number of ?? strands and carbohydrate-binding site. Carrageenan and glycan bind to different sites on AFAL. The\r\nability of AFAL binding to carrageenan can be explained by absence of the sixth ??-strand (posterior ?? sheets) and two ?? strands\r\nin frontal region. AFAL can inhibit pathway inflammatory process by carrageenan injection by connecting to it and preventing its\r\nentry into the cell and triggers the reaction
