Identification
Name:2-Isopropyl-3-oxosuccinate
Description2-Isopropyl-3-oxosuccinate is an intermediate in leucine biosynthesis and can be generated from (2R,3S)-3-Isopropylmalate. It is the third step in leucine biosynthesis after the fork from valine synthesis. It is an oxidative decarboxylation. Leucine biosynthesis involves a five-step conversion process starting with the valine precursor 2-keto-isovalerate. The final step in this pathway is catalyzed by two transaminases of broad specificity, Branched-chain amino acid transferase (IlvE) and Tyrosine aminotransferase (TyrB). In this pathway 2-Isopropyl-3-oxosuccinate is converted to 4-Methyl-2-oxopentanoate via spontaneous reaction.(BioCyc)

Enzymes

General function:
Involved in magnesium ion binding
Specific function:
Catalyzes the oxidation of 3-carboxy-2-hydroxy-4- methylpentanoate (3-isopropylmalate) to 3-carboxy-4-methyl-2- oxopentanoate. The product decarboxylates to 4-methyl-2 oxopentanoate
Gene Name:
leuB
Uniprot ID:

Molecular weight:

Reactions
(2R,3S)-3-isopropylmalate + NAD(+) = 4-methyl-2-oxopentanoate + CO(2) + NADH.
General function:
Involved in magnesium ion binding
Specific function:
Catalyzes the NAD(+)-dependent oxidative decarboxylation of D-malate into pyruvate. Is essential for aerobic growth on D- malate as the sole carbon source. But is not required for anaerobic D-malate utilization, although DmlA is expressed and active in those conditions. Appears to be not able to use L- tartrate as a substrate for dehydrogenation instead of D-malate
Gene Name:

Reactions
(R)-malate + NAD(+) = pyruvate + CO(2) + NADH.
