Fig. 4

a Schematic of coupling the peptidomimetic antibiotic Thanatin to the singlet oxygen generator (SOG) thiorhodamine. b Volcano plot showing relative abundance changes of LUX-MS quantified proteins from Thanatin-SOG treated Escherichia coli illuminated for 5 min with and without Thanatin competition, tested using a two-sided Student’s t test. Blue dots represent significantly enriched proteins and red dots represent the direct binding targets of Thanatin previously found by photo-crosslinking experiments. The main targets and selected surfaceome interactors are highlighted. c Schematic representation outlining the molecular mechanism of action of Thanatin in E. coli cells with spatial context. Source data are provided as a Source Data file and interactive volcano plots (Supplementary Data 4).
