title: Characterization of the tol-pal and cyd region of Escherichia coli K-12: transcript analysis and identification of two new proteins encoded by the cyd operon.
abstract: Sequence analysis showed that the cyd operon is immediately upstream of the tol-pal region. Northern (RNA) blot analysis demonstrated that the transcript for the cyd operon terminates just before the promoter for transcription of the tol genes. The cyd transcript contains cydA cydB followed by two open reading frames: orfC, encoding a 37-residue peptide, and orfD, encoding a 97-residue peptide. Both OrfC and OrfD are synthesized in minicells.
