2-oxoglutarate dehydrogenase, E1 and E2 components; 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-oxo [...]

Glycine cleavage system H protein; The glycine cleavage system catalyzes the degradation of glycine. The H protein shuttles the methylamine group of glycine from the P protein to the T protein.

Putative aminomethyltransferase; The glycine cleavage system catalyzes the degradation of glycine.

Pyruvate dehydrogenase E1 component; Component of the pyruvate dehydrogenase (PDH) complex, that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2).

Glycine decarboxylase; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.

Similar to M. tuberculosis Rv3859c, putative ferredoxin-dependent glutamate synthase, TR:P96218 (EMBL:Al123456) (1527 aa); Fasta score E(): 0, 90.2% identity in 1527 aa overlap and to Synechocystis sp. gltB, ferredoxin-dependent glutamate synthase 1, SW:GLTB_SYNY3 (P55037) (1550 aa); Fasta score E(): 0, 57.2% identity in 1525 aa overlap. Contains Pfam match to entry PF01493 DUF14, Domain of unknown function. Contains Pfam match to entry PF01645 Glu_synthase, Conserved region in glutamate synthase. Contains PS00095 C-5 cytosine-specific DNA methylases C-terminal signature.

Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.

Putative ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily.

Sensor histidine kinase; Member of the two-component regulatory system PrrB/PrrA that is involved specifically in early intracellular multiplication of Mycobacterium and is essential for its viability. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of PrrA. In turn, PrrA binds to the upstream promoter regions of target genes including itself to positively regulate their expression.
