CC   -!- FUNCTION: Displays esterase activity towards short chain fatty esters
CC       (acyl chain length of up to 8 carbons). Able to hydrolyze
CC       triacetylglycerol (triacetin) and tributyrylglycerol (tributyrin), but
CC       not trioleylglycerol (triolein) or cholesterol oleate. Negatively
CC       regulates MalT activity by antagonizing maltotriose binding. Inhibits
CC       MelA galactosidase activity. {ECO:0000255|HAMAP-Rule:MF_01958}.
CC   -!- SUBUNIT: Homodimer. Interacts with MalT and MelA. {ECO:0000255|HAMAP-
CC       Rule:MF_01958}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01958}.
CC   -!- SIMILARITY: Belongs to the 'GDXG' lipolytic enzyme family.
CC       {ECO:0000255|HAMAP-Rule:MF_01958}.
