Cell division protein DivIB (IPR026580)

Short name: DivIB

Overlapping homologous superfamilies


Family relationships


DivIB is a cell division protein from Gram-positive bacteria, probably homologous to Escherichia coli FtsQ. DivIB interacts with FtsL, DivIC and PBP-2B [PMID: 16936019, PMID: 20870765]. 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 [PMID: 10792716]. It is also required for efficient sporulation at all temperatures [PMID: 16936026].
