part of cytosol divisome complex FtsQBL complex FtsBL complex FtsB-FtsL complex An example of this is FtsB in E. coli (P0A6S5) in PMID:15165235 (inferred from physical interaction). GO:1990588 2014-12-15T09:33:00Z cellular_component A protein complex required for prokaryotic cell division (FtsZ-dependent cytokinesis). Part of the divisome. Assembled independently of the other divisome components in the cytoplasm prior to transport to the cell septum. In E. coli consists of FtsB and FtsL. bhm
