From: Global regulation of gene expression in response to cysteine availability in Clostridium perfringens
Intracellular concentration of sulfur compounds (A) and amino acids (B) in strain 13 grown in the presence of cystine or homocysteine. Grey or white boxes indicate the metabolite concentrations extracted from strain 13 grown in the presence of 0.5 mM cystine or 1 mM homocysteine, respectively. The mean value of three independent experiments is presented. # indicates that the metabolite is not detectable.
