WebFeb 17, 2024 · In this study, we determined X-ray structures of GFP with the two different protonated states of the chromophore with high accuracy. These structures were obtained using sufficiently low X-ray doses to avoid significant radiation damage. The chromophores are almost completely planar, as expected for FPs in their ground state (Weber et al., 1999). WebProtonation of molecules containing chromophores strongly modifies their electronic spectrum when the protonation site belongs to the chromophore itself. On the contrary, only minor changes are observed when the protonation site is not localized on the chromophore, for example in the case of tryptophan [106] (see Chapter 4.2).In protonated adenine, the …

In chemistry, protonation (or hydronation) is the adding of a proton (or hydron, or hydrogen cation), (H ) to an atom, molecule, or ion, forming a conjugate acid. (The complementary process, when a proton is removed from a Brønsted–Lowry acid, is deprotonation.) Some examples include The protonation of water … See more Protonations are often rapid, partly because of the high mobility of protons in many solvents. The rate of protonation is related to the acidity of the protonating species: protonation by weak acids is slower than … See more Protonation is usually reversible, and the structure and bonding of the conjugate base are normally unchanged on protonation.
