Molecular docking analysis of DNA ligase from Staphylococcus aureus with identical polysaccharides

Staphylococcus aureus has been recognized as an important human pathogen for more than 100 years. DNA ligase is the main protein responsible for the replication of S. aureus. DNA ligase was selected as successive target to control the replication mechanism. The antibacterial activity of polysaccharide is known. Therefore, it is of interest to study the activity of Polysaccharide analogues against DNA ligase in S. aureus using molecular docking analysis. We report ten analogues using scoring parameters with best two analogues as potential drug candidate for the combat of S. aureus infection.
