Phenol soluble modulins complexed with Curcumin: Curcumin (shown in hot pink) interacting with the Gln82, His83, Phe107:195, Ala114, Ile117:120, Lys118:198, Asp184:190, Ser185, Trp187, and Thr191 residues (shown with forest green) of phenol soluble modulins. Curcumin forms four hydrogen bonds with Lys118:194, Asp84, and Ser85 residues of the PSM’s rendering extra stability to the interaction. Lys118 seems to form two hydrogen bonds with two ortho-positioned hydroxyl residues present on the phenol ring of curcumin. (A) Ribbon image view of the interaction of PSMs with curcumin. (B) Surface topological view of the interaction of PSMs with curcumin. (C) Interacting partners of curcumin and PSM complex.
