Venus Sequence

Venus was derived from SEYFP with the following mutations: F46L
amino acid numbers relative to avGFP. show relative to SEYFP



Deposited: ,


F46L accelerates the oxidation step, leading to the enhancement of fluorescence development of YFP at 37°C. The SEYFP-F46L variant folds and forms the chromophore very efficiently at 37°C.
