Transcription analysis of the RR17-encoding gene. Time course of β-galactosidase activity was taken from a culture of the parental strain, V583, carrying the pTCV-RR17p transcriptional lacZ fusion construct (A) or the pTCV-LacSpec vector (B). Cells were grown in M9HY medium containing 750 μg/ml spectinomycin and supplemented with the following: 100 mM EA plus 40 mM CoB12 (▪); 100 mM EA (•); NCS plus 40 nM CoB12 (○); and 100 mM glucose plus 40 nM CoB12 (▵).
