FIG. 4.

The effect of thioredoxin A depletion on the transcription of genes involved in sulfur uptake and utilization. Gene names are indicated in italics. Alternative gene names for some of the genes are given in the text (see “Sulfur uptake and utilization”). Regulation (n-fold) of genes in ItrxA 25 cells compared to that of the wild type is given in parentheses next to each gene name. When gene names are in parentheses too, P values did not meet our criteria. SAH, S-adenosyl homocysteine; SRH, S-ribosyl homocysteine. Question marks indicate the involvement of an unknown factor or a postulated function.
