CC -!- FUNCTION: Peptidoglycan polymerase that is essential for cell division
CC (Probable). Functions probably in conjunction with the penicillin-
CC binding protein 3 (ftsI) (PubMed:9603865, PubMed:11807049). Required
CC for localization of FtsI (PubMed:11807049).

CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00913}.
CC -!- SUBUNIT: Forms a complex with FtsI. Interacts also with FtsL, FtsQ and
CC FtsN. {ECO:0000269|PubMed:15774864, ECO:0000269|PubMed:17185541,

CC ECO:0000269|PubMed:12423747, ECO:0000269|PubMed:9603865}; Multi-pass

CC ECO:0000269|PubMed:9603865}. Note=Localizes to the division septum.
CC Localization requires FtsZ, FtsA, FtsQ and FtsL, but not FtsI.
CC -!- DOMAIN: The periplasmic loop between transmembrane domains 7 and 8 is
CC essential for activity and the loop between transmembrane domains 9 and
CC 10 is involved in the recruitment of FtsI at the division site.
CC {ECO:0000269|PubMed:15576787}.
CC -!- SIMILARITY: Belongs to the SEDS family. FtsW subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00913, ECO:0000305}.
CC -!- CAUTION: Has previously been proposed to be a lipid II flippase that
CC transports lipid-linked peptidoglycan precursors from the inner to the
CC outer leaflet of the cytoplasmic membrane (PubMed:21386816,
CC PubMed:24711460), but recent evidence suggests that FtsW may function
CC as a peptidoglycan polymerase (PubMed:27643381). The identity of the
CC lipid II flippase is still controversial with conflicting in vivo and
CC in vitro results, but MurJ (AC P0AF16) is probably the lipid II
CC flippase. {ECO:0000305}.
