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 [...]

Rv0843, (MTV043.36), len: 334 aa. Probable dehydrogenase, similar to various dehydrogenases e.g. Q46142|Q46142 TPP-dependent acetoin dehydrogenase (326 aa),FASTA scores: opt: 500, E(): 2.4e-26, (32.3% identity in 300 aa overlap); P51267|ODPA_PORPU pyruvate dehydrogenase E1 component from Porphyra purpurea (344 aa), FASTA scores: opt: 451, E(): 4.7e-23, (29.6% identity in 311 aa overlap); etc. Also similar to Rv2497c|pdhA pyruvate dehydrogenase E1 component from Mycobacterium tuberculosis (367 aa).

Probable branched-chain keto acid dehydrogenase E1 component, alpha subunit BkdA; 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).

Probable soluble pyridine nucleotide transhydrogenase; Conversion of NADPH, generated by peripheral catabolic pathways, to NADH, which can enter the respiratory chain for energy generation; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.

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 [...]

Rv0794c, (MTV042.04c), len: 499 aa. Probable oxidoreductase, possibly dihydrolipoamide dehydrogenase or mercuric reductase. Highly similar to CAB62675.1|AL133422 probable oxidoreductase from Streptomyces coelicolor (477 aa); and similar to various oxidoreductases e.g. P08663|MERA_STAAU mercuric reductase (HG(II) reductase) from Staphylococcus aureus (547 aa); AAK70920.1|AC087551_19|AC087551 putative lipoamide dehydrogenase from Oryza sativa (563 aa); NP_437349.1|NC_003078 putative FAD-dependent pyridine nucleotide-disulphide oxidoreductase, similar to mercuric reductases protein from S [...]

NADPH-dependent mycothiol reductase Mtr; Catalyzes the NAD(P)H-dependent reduction of mycothione (the oxidized disulfide form of mycothiol) to mycothiol. Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.

NAD(P)H quinone reductase LpdA; May contribute to virulence by increasing resistance to reactive oxygen intermediates. It can reduce 2,6-dimethyl-1,4- benzoquinone (DMBQ), 5-hydroxy-1,4-naphthaquinone (5-HNQ) and menadione. NADPH is the physiological reductant rather than NADH.

Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) and of the decaprenylphosphoryl-arabinose (DPA), an essential precursor for the mycobacterial cell wall biosynthesis. Catalyzes the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P) to yield phosphoribosyl diphosphate (PRPP) and AMP. It can also use GTP, CTP and UTP as diphosphoryl donors.
