SPI1085g3 Cys448Ser variant
Protein DomainSPI1085g3 Cys448Ser variant is a cyanobacteriochrome GAF-domain mutant derived from the Spirulina protein SPI1085g3, generated by replacing Cys448 with Ser. In the reported study, this variant retained the photoswitchable fluorescent behavior of SPI1085g3 while showing slightly improved fluorescence quantum yield and nearly 13-fold faster dark reversion.
