Northern blot analysis of the T-box controlled cysP2 transcription. Total RNA was extracted from strain 13 grown in minimal medium in the presence of cystine 1 mM (C) or homocysteine 1 mM (HC). Specific RNAs were detected using a probe hybridizing with the T-box region (A) or with the cysP2 (cpe0967) gene (B). The 16 S rRNA was used as a loading control.
