Transcriptional analysis of the D. circinale AWQC131C sxt cluster. Genes required for PST biosynthesis are transcribed by a minimum of four mRNA transcripts from two bi-directional promoter regions encoding five promoters; PsxtD (operon 1), PsxtP (operon 2), PsxtPER1 (TU 3), PsxtPER2 (TU 3) and Porf24 (operon 4). Direction of transcription is indicated by black arrows
