Operon evidence: Northern blotting (1.8 kb transcript); S1 nuclease mapping of the 3' end
Reference: Holmberg C, et al. (1990), Beijer L, et al. (1993), Holmberg C & Rutberg L (1991), Holmberg C & Rutberg L (1992)
Comments: The Northern blotting experiment showed a 4.4 kb glpFKD transcript due to readthrough of the glpFK terminator. However, the promoter in front of glpD is the major promoter for glpD transcription. The S1 nuclease mapping results show that transcription ends in the section CCGTTATTTC. Transcriptional terminatation at the stem-loop downstream of the glpD promoter is alleviated by GlpP binding to the ribosomal antiterminator (RAT) sequence in the presence of glycerol-3-phosphate.
