Fig. 5. The simultaneous absence of Grx3 and Grx4 induces accumulation of cells in G1. FACS profiles of different strains growing exponentially in SD medium plus amino acids. The strains are: wild type, grx3, grx4, grx3grx4, wild type overexpressing Aft1, grx3grx4aft1, wild type overexpressing Grx3 and wild type overexpressing Grx4. All the proteins tested were overexpressed under the tetO7 promoter.
