RT "Complete sequence of Escherichia coli C str. ATCC 8739.";
RL Submitted (FEB-2008) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the retro-aldol cleavage of 4-hydroxy-2-
CC oxopentanoate to pyruvate and acetaldehyde. Is involved in the meta-
CC cleavage pathway for the degradation of aromatic compounds.
CC {ECO:0000255|HAMAP-Rule:MF_01656}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-4-hydroxy-2-oxopentanoate = acetaldehyde + pyruvate;
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 -!- PATHWAY: Aromatic compound metabolism; 3-phenylpropanoate degradation.
CC {ECO:0000255|HAMAP-Rule:MF_01656}.
CC -!- SUBUNIT: Interacts with MhpF. {ECO:0000255|HAMAP-Rule:MF_01656}.
CC -!- SIMILARITY: Belongs to the 4-hydroxy-2-oxovalerate aldolase family.
CC {ECO:0000255|HAMAP-Rule:MF_01656}.
