Mutants unable to grow on medium containing glutathione as a sole source of sulphur (GSH medium) were isolated from Saccharomyces cerevisiae strains carrying met17(deficiency of O-acetylserine and O-acetylhomoserine sulphydrylase). They were defective in the high-affinity glutathione transport system, GSH-P1. Newly acquired mutations belonged to the same complementation group, gsh11. However, it became apparent that gsh11 conferred the mutant phenotype not by itself but in collaboration with met17. Moreover, mutations conferring the defect in sulphate assimilation made the cell unable to grow on GSH medium in collaboration with gsh11. From this finding, we propose that the sulphate assimilation pathway acts as a sulphur-recycling system and that this function is especially vital to the cell when the supply of glutathione is limited.
