Updated annotation (from data): branched-chain ketoacid ferredoxin reductase (EC 1.2.7.7) active on 4-methyl-2-oxopentanoate, (S)-3-methyl-2-oxopentanoate, or 3-methyl-2-oxobutanoate Rationale: Specifically important for: L-Leucine; L-Isoleucine. This oxidizes and decarboxylates the alpha-keto acid that is produced by a branched chain amino acid dehydrogenase (4-methyl-2-oxopentanoate or (S)-3-methyl-2-oxopentanoate). This is also improtant for utilization of valine as a nitrogen source implying a third substrate (3-methyl-2-oxobutanoate). Original annotation: Indolepyruvate ferredoxin oxidoreductase, alpha and beta subunits Type 1: Protein-coding gene Located on scaffold Psest_Contig47.1, - strand, nucleotides 3,694,196 to 3,697,666 See nucleotide sequence around Psest_3517 or for all of scaffold Psest_Contig47.1
