obsolete 3-methyl-2-oxobutanoate dehydrogenase (lipoamide) complex https://github.com/geneontology/go-ontology/issues/21246 https://github.com/geneontology/go-ontology/issues/26881 true GO:0017086 The reason for obsoletion is that this term is equivalent to GO:0160157 branched-chain alpha-ketoacid dehydrogenase complex. branched-chain alpha-ketoacid dehydrogenase complex BCADH GO:0031212 cellular_component OBSOLETE. A protein complex that catalyzes the reaction 3-methyl-2-oxobutanoate + lipoamide = S-(2-methylpropanoyl)-dihydrolipoamide + carbon dioxide (CO2). This requires thiamine diphosphate; the enzyme also acts on (S)-3-methyl-2-oxopentanoate and 4-methyl-2-oxo-pentanoate. branched-chain alpha-ketoacid dehydrogenase complex
