CC   -!- FUNCTION: Negative regulator of FtsZ ring formation; modulates the
CC       frequency and position of FtsZ ring formation. Inhibits FtsZ ring
CC       formation at polar sites. Interacts either with FtsZ or with one of its
CC       binding partners to promote depolymerization. {ECO:0000255|HAMAP-
CC       Rule:MF_00728}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00728};
CC       Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00728}.
CC       Note=Colocalized with FtsZ to the nascent septal site.
CC       {ECO:0000255|HAMAP-Rule:MF_00728}.
CC   -!- SIMILARITY: Belongs to the EzrA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00728}.
