Fig. 6From: Superior anti-pulmonary viral potential of Natrialba sp. M6-producing surfactin and C50 carotenoid pigment with unveiling its action modesThe inhibition potential on SARS-CoV-2 in the term of suppressing 3-chymotrypsin like (3CL) protease activity with illustrating molecular docking analysis. A Inhibition percentages of biosurfactant (Sur) and carotenoid pigment (Pig) for 3CL protease activity. B 3D binding mode of surfactin (green sticks) into the co-crystallized ligand (yellow sticks) binding site (molecular surface), C 2D interactions of surfactin, and D 2D interactions of the co-crystallized ligand within the prepared crystal structure of SARS-CoV-2 3CL protease (PDB ID: 7VTH)Back to article page
