CC -!- FUNCTION: Involved in cholesterol degradation. Catalyzes the retro-
CC aldol cleavage of 4-hydroxy-2-oxohexanoate (HOHA) to pyruvate and
CC propanal. Can also catalyze the cleavage of 4-hydroxy-2-oxopentanoate
CC (HOPA) to pyruvate and acetaldehyde. The aldehydes produced by this
CC reaction are directly channeled to the dehydrogenase HsaG.
CC {ECO:0000250|UniProtKB:P9WMK5}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-4-hydroxy-2-oxohexanoate = propanal + pyruvate;
CC Xref=Rhea:RHEA:36003, ChEBI:CHEBI:15361, ChEBI:CHEBI:17153,
CC ChEBI:CHEBI:73142; EC=4.1.3.43;

CC Evidence={ECO:0000250|UniProtKB:P9WMK5};
CC -!- CATALYTIC ACTIVITY:

CC Xref=Rhea:RHEA:22624, ChEBI:CHEBI:15343, ChEBI:CHEBI:15361,
CC ChEBI:CHEBI:73143; EC=4.1.3.39; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01656};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:22625;
CC Evidence={ECO:0000250|UniProtKB:P9WMK5};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:P9WMK5};
CC -!- SUBUNIT: Homodimer. Forms an heterotetramer composed of two aldolase
CC (HsaF) and two dehydrogenase (HsaG) subunits.
CC {ECO:0000250|UniProtKB:P9WMK5}.
CC -!- SIMILARITY: Belongs to the 4-hydroxy-2-oxovalerate aldolase family.
CC {ECO:0000255|HAMAP-Rule:MF_01656}.
