Why do the concentrations of potassium glutamate and magnesium glutamate differ between compositions? Which is more sensitive? Potassium glutamate functions to reproduce the intracellular environment of E.coli by contributing to the ionic environment. Magnesium glutamate’s role is for magnesium to interact with the negatively charged phosphate groups in nucleic acids, as well as playing a role in the activity + stability of transcription and translation machinery. Despite this, too much magnesium can reduce protein synthesis; therefore, its concentration must be optimized rather than just increased.Hugoen
