Impacts of perturbing FtsZ GTPase activity, either due to mutation or treatment with PC190723 following Z-ring assembly

Species	PG Enzyme Recruitment	Constriction	PG enzyme movement rate	Septum morphology
E. coli	Still occurs	Still occurs	Fast, inactive population correlates with FtsZ treadmilling rate; slow, active population does not	Aberrant morphology
B. subtilis	Still occurs	Still occurs if already initiated; rate correlates with FtsZ treadmilling rate	Correlates with FtsZ treadmilling rate	No reported change
S. pneumoniae	Still occurs	Fails for GTPase-deficient FtsZ; ??? for PC addition after start of constriction	Does not correlate with FtsZ treadmilling rate	No reported change
S. aureus	Still occurs	Still occurs if already initiated	???	No reported change
