Depositor Comments

Full name of this plasmid is pFA6a-link-yESapphire-SpHIS5. yESapphire is created by mutagenesis from a codon-optimized green fluorescent protein - yEGFP1 (Cormack et al. 1997). This yEGFP variant is cloned into pDH5, replacing YFP. An codon-optimized linker was added into the yEGFP variant to improve expression level. The selectable marker, Sz. pombe HIS5 (SpHIS5), complements S. cerevisiae HIS3.

The yeast GFP used to create this plasmid contained a point mutation M233I that is present in all GFP variants derived from this original yEGFP. The mutation had no effect on fluorescence (see associated publication for more details).
