Transcription profiling of yeast strains lacking Met4 or Met4 cofactors at time points after sulfur limitation

ABSTRACT: All yeast strains used in this study (Table 1) are in the W303 background (ade2-1 can1-100, his3-1,15 leu2-3,112 trp1-1 ura3). For sulfur limitation microarray studies, WT, met4 delete, met31 delete met32 delete, cbf1 delete, and met28 delete strains were grown in minimal B-media [see Cherest, H., and Surdin-Kerjan, Y. (1992). Genetic analysis of a new mutation conferring cysteine auxotrophy in Saccharomyces cerevisiae: updating of the sulfur metabolism pathway. Genetics 130, p51-58 for B-media composition] supplemented with 0.5mM methionine as the sole sulfur source. An aliquot of cells was harvested for a t=0 time point while the remainder were filtered through a .22um Stericup filter (Millipore), then washed and resuspended in pre-warmed (30 C) B-media lacking any source of sulfur. Cells were harvested after 20, 40, and 80 minutes.
