Figure 2From: Dissecting and engineering of the TetR family regulator SACE_7301 for enhanced erythromycin production in Saccharopolyspora erythraea Effects of SACE_7301 overexpression on transcriptional levels of eryAI and ermE . qRT-PCR was used to quantify the amounts of transcripts produced by A226/pZMW, and A226/pZMW7301 cultured in R5 fermentation medium for 2 (A) or 4 days (B). Mean values of at least three replicates were shown, with the standard deviation indicated by error bars.Back to article page
