Gougerotin is a peptidyl nucleoside antibiotic. It functions as a specific inhibitor of protein synthesis by binding ribosomal peptidyl transferase and exhibits a broad spectrum of biological activities. gouR, situated in the gougerotin biosynthetic gene cluster, encodes a TetR family transcriptional regulatory protein. Gene disruption and genetic complementation revealed that gouR plays an important role in the biosynthesis of gougerotin. Transcriptional analysis suggested that GouR represses the transcription of the gouL-to-gouB operon consisting of 11 structural genes and activates the transcription of the major facilitator superfamily (MFS) transporter gene (gouM). Electrophoresis mobility shift assays (EMSAs) and DNase I footprinting experiments showed that GouR has specific DNA-binding activity for the promoter regions of gouL, gouM, and gouR. Our data suggested that GouR modulates gougerotin production by coordinating its biosynthesis and export in Streptomyces graminearus.
