FIG. 4.
Increased transcription of amino acid catabolism genes in NZ131 rgg::ermAB. The quantities of transcripts encoding arginine deiminase (sagP) and the putative α subunit of serine dehydratase (sdhA) were determined with quantitative RT-PCR. The quantity of cDNA for each gene was normalized to the quantity of gyrA cDNA in each RNA sample. The values shown are the means ± standard errors of the means from two independently isolated RNA preparations analyzed in triplicate.
