MetaCyc Pathway: L-valine degradation I in Marinobacter adhaerens HP15

Branched-chain-amino-acid transaminase:
L-valine + 2-oxoglutarate→3-methyl-2-oxobutanoate + L-glutamate (EC 2.6.1.42)

2-oxoisovalerate dehydrogenase (acylating):
3-methyl-2-oxobutanoate + coenzyme A + NAD⁺→isobutanoyl-CoA + CO₂ + NADH (EC 1.2.1.25)

isobutanoyl-CoA + an oxidized electron-transfer flavoprotein + H⁺→methylacrylyl-CoA + a reduced electron-transfer flavoprotein (EC 1.3.8.5)

No genes

methylacrylyl-CoA + H₂O→(S)-3-hydroxy-isobutanoyl-CoA (EC 4.2.1.150)

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
