SYFP2 Sequence

SYFP2 was derived from mVenus with the following mutations: L68V
amino acid numbers relative to avGFP. show relative to mVenus

GenBank: DQ092361


Changing leucine68 back to valine decreased the relative bleaching time of SYFP2 by 30%. Thus, mutation V68L contributes to the photostability of YFP.
