Note(s): The transcription of this transcription unit is induced during the exponential growth phase, reaching a plateau in the stationary phase Montero M,2011
Montero et al. Montero M,2011did not find experimentally the transcription start sites upstream of glgC that had been reported by T. Romeo and J. Preiss in 1989 Romeo T,1989 Montero et al. suggested that only the promoters glgBp and glgAp transcribe the genes of this operon and that glgBp is the main promoter directing the expression of the operon Montero M,2011
