High impact information on psbT

  • Thus, by specific transcription initiation at the psbN gene promoter, SIG3-PEP holoenzyme could also influence the expression of the psbB operon by producing psbT antisense RNA [1].
  • We show that this antisense RNA is not limited to the intergenic region, i.e. it does not terminate at the end of the psbN gene but extends as antisense transcript to cover the whole psbT coding region [1].
