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}.
