Probable branched-chain keto acid dehydrogenase E1 component, beta subunit BkdB; Component of the branched-chain alpha-ketoacid dehydrogenase (BCKADH) complex, that catalyzes the overall conversion of branched- chain alpha-ketoacids to acyl-CoA and CO(2).

Dihydrolipoyl dehydrogenase; Lipoamide dehydrogenase is an essential component of the alpha-ketoacid dehydrogenase complexes, namely the pyruvate dehydrogenase (PDH) complex, the branched-chain alpha-ketoacid dehydrogenase (BCKADH) complex, and likely also the 2-oxoglutarate dehydrogenase (ODH) complex. Catalyzes the reoxidation of dihydrolipoyl groups which are covalently attached to the lipoate acyltransferase components (E2) of the complexes. Is also able to catalyze the transhydrogenation of NADH and thio-NAD(+) in the absence of D,L- lipoamide, and the NADH-dependent reduction of [...]

DlaT, dihydrolipoamide acyltransferase, E2 component of pyruvate dehydrogenase; Component of the pyruvate dehydrogenase (PDH) complex, that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). Appears to be essential for Mtb pathogenesis.

Multifunctional alpha-ketoglutarate metabolic enzyme; Shows three enzymatic activities that share a first common step, the attack of thiamine-PP on 2-oxoglutarate (alpha-ketoglutarate, KG), leading to the formation of an enamine-thiamine-PP intermediate upon decarboxylation. Thus, displays KGD activity, catalyzing the decarboxylation from five-carbon 2-oxoglutarate to four-carbon succinate semialdehyde (SSA). Also catalyzes C-C bond formation between the activated aldehyde formed after decarboxylation of alpha- ketoglutarate and the carbonyl of glyoxylate (GLX), to yield 2-hydroxy- 3-o [...]

Pyruvate dehydrogenase E1 component; Component of the pyruvate dehydrogenase (PDH) complex, that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). AceE has reductase activity with pyruvate but does not react with 2- oxoglutarate.

Probable oxidoreductase (alpha subunit); Component of KG oxidoreductase (KOR) that catalyzes the CoA- dependent oxidative decarboxylation of 2-oxoglutarate (alpha- ketoglutarate, KG) to succinyl-CoA. Methyl viologen can act as electron acceptor in vitro; the physiologic electron acceptor is unknown. Is involved in the alternative TCA pathway that functions concurrently with fatty acid beta-oxidation. Since a growing body of evidence indicates that lipids (for example cholesterol and fatty acids) are a predominant growth substrate for M.tuberculosis during infection, flux through KOR li [...]
