CC -!- FUNCTION: Catalyzes the reversible hydration of cis-homoaconitate to
CC (2R,3S)-homoisocitrate, a step in the alpha-aminoadipate pathway for
CC lysine biosynthesis. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2R,3S)-homoisocitrate = cis-homoaconitate + H2O;
CC Xref=Rhea:RHEA:15485, ChEBI:CHEBI:15377, ChEBI:CHEBI:15404,
CC ChEBI:CHEBI:58174; EC=4.2.1.36;
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000250};
CC Note=Binds 1 [4Fe-4S] cluster per subunit. {ECO:0000250};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via AAA
CC pathway; L-alpha-aminoadipate from 2-oxoglutarate: step 3/5.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the aconitase/IPM isomerase family.
CC {ECO:0000305}.
