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.
