Component of the SOS system and an inhibitor of cell division. Accumulation of SulA causes rapid cessation of cell division and the appearance of long, non-septate filaments. In the presence of GTP, binds a polymerization-competent form of FtsZ in a 1:1 ratio, thus inhibiting FtsZ polymerization and therefore preventing it from participating in the assembly of the Z ring. This mechanism prevents the premature segregation of damaged DNA to daughter cells during cell division. The effect of overexpression of SulA is neutralized by antitoxin CbeA (yeeU).

In current work the recovery of division process of Escherichia coli cells after division arrest due to expression of SOS-response protein SulA was studied. Data indicate that cells are able to rapidly restore normal division; also nucleoid occlusion seems to be the main septum positioning mechanism during the process. PMID: 30188109
results indicate existence of a SulA-dependent pathway of high-pressure-induced cell filamentation and suggest involvement of the SOS response, and particularly of SulA, in high-pressure-mediated cell death in strains which are compromised in Lon function PMID: 15748989
Results found that the binding of SulA to FtsZ is necessary but not sufficient for inhibition of FtsZ polymerization. PMID: 18245292
