MetaCyc Pathway: L-valine biosynthesis in Marinobacter adhaerens HP15

Acetolactate synthase:
2 pyruvate + H⁺→(S)-2-acetolactate + CO₂ (EC 2.2.1.6)

Ketol-acid reductoisomerase (in reverse):
(S)-2-acetolactate + NADPH + H⁺→(2R)-2,3-dihydroxy-3-methylbutanoate + NADP⁺ (EC 1.1.1.86)

HP15_533

Dihydroxy-acid dehydratase:
(2R)-2,3-dihydroxy-3-methylbutanoate→3-methyl-2-oxobutanoate + H₂O (EC 4.2.1.9)

HP15_3363

HP15_595

Branched-chain-amino-acid transaminase (in reverse):

Candidate genes for each reaction are identified from best hits to MetaCyc; by matching EC numbers (which are assigned by TIGRFam, SEED, or best hits to KEGG); or by matching SEED roles to KEGG reactions to MetaCyc reactions. See the "Protein" tab of each gene for more information
