Recently, scientists from the California Institute of Technology have discovered a protein that may be vital to treating drug-resistant bacteria. This research resulted from the conclusion that bacteria will be constantly evolving, thus inevitably becoming immune to all of our current antibiotics. Three proteins called MraY, MurG, and MurJ were found to have been a key component in the creation of the cell wall by driving the movement of peptidoglycan across the inner bacterial membrane. While medicine such as penicillin and amoxicillin already target peptidoglycan in order to fight back against these bacteria, it is soon becoming not as effective against new and current bacteria species. So, these scientists have discovered that if any one of those three proteins mentioned above fail, then peptidoglycan cannot be produced. However, researchers have stated that many mechanistic details about these proteins remain unclear. Additionally, these scientists have also discovered that single-gene lysis proteins called Sgls, bind to MurJ, effectively blocking the transport of peptidoglycan. I think that this study is very fascinating since it could ultimately lead to a totally new method of how antibiotics work and are created.
