RL Submitted (JAN-2012) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the isomerization between 2-isopropylmalate and 3-
CC isopropylmalate, via the formation of 2-isopropylmaleate.
CC {ECO:0000256|HAMAP-Rule:MF_01032}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2R,3S)-3-isopropylmalate = (2S)-2-isopropylmalate;
CC Xref=Rhea:RHEA:32287, ChEBI:CHEBI:1178, ChEBI:CHEBI:35121;
CC EC=4.2.1.33; Evidence={ECO:0000256|HAMAP-Rule:MF_01032};
CC -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine
CC from 3-methyl-2-oxobutanoate: step 2/4. {ECO:0000256|HAMAP-
CC Rule:MF_01032}.
CC -!- SUBUNIT: Heterodimer of LeuC and LeuD. {ECO:0000256|HAMAP-
CC Rule:MF_01032}.
CC -!- SIMILARITY: Belongs to the LeuD family. LeuD type 2 subfamily.
CC {ECO:0000256|ARBA:ARBA00009869, ECO:0000256|HAMAP-Rule:MF_01032}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
