Sažetak
Streptococcus gordonii and Streptococcus mutans are oral bacteria that grow as a plaque biofilm on the tooth surface. The metabolic production of hydrogen peroxide produced by S. gordonii can inhibit the growth of S. mutans, the primary causative agent of human dental caries. [1] Manganese ions (Mn2+) are an essential nutrient for pathogenic bacteria and has been linked to virulence in many species. [2] The expression of Mn2+-selective ABC transporters in streptococci is under the regulatory control of a group of homologous metalloregulatory proteins, including ScaR from S. gordonii, and SloR from S. mutans. [3] To investigate the influence of Mn2+ ion binding on structural and dynamical properties of SloR and ScaR, we conducted molecular dynamic simulations of both proteins. The computational results were validated by experimental methods: circular dichrosim (CD) and differential scanning calorimetry (DSC)
