Ph sensing mechanism
WebJul 24, 2014 · The pH-sensing mechanism appears to be mediated by cation–π interactions between proton and the aromatic side chain of Tyr74. The identification of the pH sensor and the proposed mechanism of pH sensing contribute to mechanistic understanding of the pH-dependent acid resistance in bacteria. Abstract WebOct 13, 2024 · The sensing mechanism of an aminorhodamine (TMARh) pH probe is investigated using femtosecond transient absorption spectroscopy and quantum chemical calculations, showing that this probe is best understood using the bichromophore model rather than the more common models such as photoinduced electron transfer or …
