STRING protein interaction network of potential FtsK_N interaction partners identified by mass spectrometry. Proteins shown were identified exclusively in UV treated samples of FtsK_N* variants W51*, D135*, D136*, Y139* and L158* (absent in untreated and WT controls). Interactions were determined using STRING 10.0⁶⁵. Lines indicate known or predicted protein-protein interactions, with thicker lines indicating higher levels of confidence (minimum interaction score, 0.4). Models of known protein structures are shown inside the corresponding protein spheres. Blue text highlights proteins involved in elongation and cell division, red text indicates proteins involved in general peptidoglycan modification. FtsK is circled and highlighted in yellow.
