FtsQ/DivIB bacterial division proteins (Pfam:PF03799) contain an N-terminal POTRA domain (for polypeptide-transport-associated domain). This is found in different types of proteins, usually associated with a transmembrane beta-barrel. FtsQ/DivIB may have chaperone-like roles, which has also been postulated for the POTRA domain in other contexts [1].
FtsQ is an essential cell division protein. It may link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic [1]. FtsQ may control the corre ...
FtsQ is an essential cell division protein. It may link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic [1]. FtsQ may control the correct divisome assembly [2]. DivIB is a cell division protein from Gram-positive bacteria, probably homologous to Escherichia coli FtsQ. DivIB interacts with FtsL, DivIC and PBP-2B [3,4]. DivIB plays an essential role in division at high temperatures, maybe by protecting FtsL from degradation or by promoting formation of the FtsL-DivIC complex [5]. It is also required for efficient sporulation at all temperatures [6]. FtsQ and DivIB have a short N-terminal cytoplasmic domain and a larger C-terminal periplasmic domain [2,4]. This entry represents the C-terminal region.
