From: CtcS, a MarR family regulator, regulates chlortetracycline biosynthesis
Analysis of CTC and TC production in different strains. a Time-course analysis of TC and CTC production in ∆ctcS and WT strains. b Quantitative analysis of TC and CTC production in ∆ctcS, ∆ctcS::pPM927, ∆ctcS::ctcS, WT, WT::pIB139 and WT::ctcS strains. For comparison, the yield in ∆ctcS strain are determined as 1. Error bars showed the standard deviation of three independent experiments
