CC   -!- FUNCTION: Required for optimal enterobactin synthesis. Acts as a
CC       proofreading enzyme that prevents EntB misacylation by hydrolyzing the
CC       thioester bound existing between EntB and wrongly charged molecules.
CC       {ECO:0000255|HAMAP-Rule:MF_00907}.
CC   -!- PATHWAY: Siderophore biosynthesis; enterobactin biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00907}.
CC   -!- SUBUNIT: Homotetramer. Dimer of dimers. Interacts specifically with the
CC       aryl carrier protein (ArCP) domain of EntB. {ECO:0000255|HAMAP-
CC       Rule:MF_00907}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00907}.
CC   -!- SIMILARITY: Belongs to the thioesterase PaaI family.
CC       {ECO:0000255|HAMAP-Rule:MF_00907}.
