Direct Visualization of a Hydroperoxy Intermediate in Fluorescent Protein Chromophore Maturation in PAmCherry1

Abstract Despite the widespread use of fluorescent proteins in bioimaging, the mechanism of oxidative chromophore maturation to form the tyrosine Cα═Cβ double bond remains unclear. In the photoactivatable fluorescent protein PAmCherry1, this double bond has not yet been formed pr...
