FtsZ protofilaments use a hinge-opening mechanism for constrictive force generation

摘　　要：FtsZ is a guanosine triphosphatase(GTPase)that polymerizes into protofilaments at the bacterial division site.These protofilaments further organize to a structure termed the Z ring.Z ring recruits the accessory division proteins to the septum and also provides mechanical forces needed to constrict the membrane and reduce the cell width,However,how Z ring generates mechanical force is unclear.While oneFtsZ is a guanosine triphosphatase（GTPase）that polymerizes into protofilaments at the bacterial division site.These protofilaments further organize to a structure termed the Z ring.Z ring recruits the accessory division proteins to the septum and also provides mechanical forces needed to constrict the membrane and reduce the cell width,However,how Z ring generates mechanical force is unclear.
