Figure 2From: Two heterologously expressed Planobispora rosea proteins cooperatively induce Streptomyces lividans thiostrepton uptake and storage from the extracellular mediumFeeding experiments. (a) Thin Layer Chromatography followed by bioassays on M. luteus and (b) autoradiography showing radio-labeled thiostrepton (1); SL-ESAC (2), S. laurentii (3) and SL-3.5 (4) radioactive extracts. Solvent: acetone. Asterisks indicate the substance present in SL-ESAC and SL-3.5 that are not active and are different from thiostrepton.Back to article page
