CC -!- FUNCTION: Mediates the hydrolysis of steryl esters, thereby playing a
CC central role in lipid metabolism. Under heme-deficient conditions, it
CC constitutes the major steryl ester hydrolase, suggesting that it plays
CC a central role in mobilization of steryl esters under anaerobic
CC conditions. {ECO:0000269|PubMed:15713625, ECO:0000269|PubMed:16835446}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a sterol ester + H2O = a fatty acid + a sterol + H(+);
CC Xref=Rhea:RHEA:10100, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15889, ChEBI:CHEBI:28868, ChEBI:CHEBI:35915; EC=3.1.1.13;
CC Evidence={ECO:0000269|PubMed:15713625};
CC -!- SUBCELLULAR LOCATION: Lipid droplet. Membrane; Peripheral membrane
CC protein.
CC -!- INDUCTION: Under heme-deficiency conditions. Heme-deficient induction
CC requires ROX3. {ECO:0000269|PubMed:16835446}.
CC -!- PTM: Not N-glycosylated.
CC -!- MISCELLANEOUS: Present with 7770 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. {ECO:0000305}.
