AvGFP chromophore formation

Fig. 5.2. Chromophore formation in avGFP and DsRed. Chromophore formation in avGFP (A) requires folding of the tripeptide into the right conformation in order to enable cyclization and oxidation to form the mature green chromophore. In DsRed (B) chromophore formation follows the same path as for avGFP but requires an additional oxidation step to extend the conjugation of the chromophore.
