CC   -!- FUNCTION: Component of the SOS system and an inhibitor of cell
CC       division. Accumulation of SulA causes rapid cessation of cell division
CC       and the appearance of long, non-septate filaments. In the presence of
CC       GTP, binds a polymerization-competent form of FtsZ in a 1:1 ratio, thus
CC       inhibiting FtsZ polymerization and therefore preventing it from
CC       participating in the assembly of the Z ring. This mechanism prevents
CC       the premature segregation of damaged DNA to daughter cells during cell
CC       division. {ECO:0000255|HAMAP-Rule:MF_01179}.
CC   -!- SUBUNIT: Interacts with FtsZ. {ECO:0000255|HAMAP-Rule:MF_01179}.
CC   -!- INDUCTION: By DNA damage, as part of the SOS response.
CC       {ECO:0000255|HAMAP-Rule:MF_01179}.
CC   -!- PTM: Is rapidly cleaved and degraded by the Lon protease once DNA
CC       damage is repaired. {ECO:0000255|HAMAP-Rule:MF_01179}.
CC   -!- SIMILARITY: Belongs to the SulA family. {ECO:0000255|HAMAP-
CC       Rule:MF_01179}.
