Figure 4From: Dissecting and engineering of the TetR family regulator SACE_7301 for enhanced erythromycin production in Saccharopolyspora erythraea Effects of overexpression of SACE_7301 on erythromycin biosynthesis in S. erythraea A226. (A) Schematic illustration of the strategy for construction of expression plasmids with 1 to 3 copies of SACE_7301. (B) Er-A production of A226 and SACE_7301-overexpressed mutants. (C) qRT-PCR analyses of gene transcription in A226 and SACE_7301-overexpressed mutants. Mean values of at least three replicates were shown, with the standard deviation indicated by error bars.Back to article page
