Interruption of folate metabolism by trimethoprim results in the elevated expression of folate stress proteins in Escherichia coli. E. coli grown in culture medium supplemented with the folate-dependent metabolites glycine, methionine, and the purine nucleoside inosine shows reduced expression of folate stress proteins. The folate stress proteins include the universal stress protein, the ferric uptake regulatory repressor, and possibly, lipoamide dehydrogenase, the L protein component of the glycine cleavage enzyme complex.
