SHardonnay Sequence

SHardonnay was derived from EYFP with the following mutations: Y203F
amino acid numbers relative to avGFP. show relative to EYFP



Deposited: ,


Our hypothesis also inspired the generation of an eYFP mutant, eliminating the centrosymmetry in the eYFP chromophore by replacing Tyr203 with Phe203 through site-directed mutagenesis. The mutant was named SHardonnay for its improved second-harmonic properties and for its color appearance similar to white wine of the Chardonnay grape.
