Acetyl/propionyl-CoA carboxylase (beta subunit) AccD6; Rv2247, (MTCY427.28), len: 473 aa. AccD6,Acetyl/Propionyl CoA Carboxylase, beta subunit (see citations below), highly similar to e.g. PCCB_RHOSO|Q06101 propionyl-CoA carboxylase beta chain, FASTA score: (75.1% identity in 437 aa overlap). Similar to many other Acetyl/Propionyl CoA Carboxylases from Mycobacterium tuberculosis. Belongs to the AccD / PccB family.

Rv3285, (MTCY71.25), len: 600 aa. Probable accA3,bifunctional protein acetyl-/propionyl-coenzyme A carboxylase, alpha chain (see citations below) equivalent to P46392|BCCA_MYCLE|BCCA|ML0726|B1308_C1_129 acetyl-/propionyl-coenzyme A carboxylase alpha chain from Mycobacterium leprae (598 aa), FASTA scores: opt: 3510,E(): 1.1e-196, (89.3% identity in 601 aa overlap). Also highly similar to other proteins e.g. P71122|ACCBC acyl coenzyme A carboxylase from Corynebacterium glutamicum (Brevibacterium flavum) (591 aa), FASTA scores: opt: 2776,E(): 5.6e-154, (71.95% identity in 592 aa overlap); [...]

BirA protein; Rv3279c, (MTCY71.19c), len: 266 aa. Possible birA,bifunctional protein: biotin operon repressor and biotin--[acetyl-CoA-carboxylase] synthetase, equivalent to Q9CCL3|BIRA|ML0732 biotin APO-protein ligase from Mycobacterium leprae (274 aa), FASTA scores: opt: 1189,E(): 2.3e-66, (71.2% identity in 271 aa overlap). But as it lacks a BirA h-t-h domain at N-terminus, may simply be biotin apo-protein ligase. Also similar to others e.g. Q9CNX6|BIRA|PM0296 from Pasteurella multocida (312 aa),FASTA scores: opt: 347, E(): 2.7e-14, (32.95% identity in 270 aa overlap); Q9HWC0|BIRA|PA [...]

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 [...]

Probable phosphate acetyltransferase Pta (phosphotransacetylase); Involved in acetate metabolism; In the C-terminal section; belongs to the phosphate acetyltransferase and butyryltransferase family.

Malate synthase G GlcB; Involved in the glycolate utilization. Catalyzes the condensation and subsequent hydrolysis of acetyl-coenzyme A (acetyl- CoA) and glyoxylate to form malate and CoA.

Acetyl-coenzyme A synthetase; Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. AcsA undergoes a two-step reaction. In the first half reaction, AcsA combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA. M.tuberculosis may use AcsA for both acetate and propionate assimilation; Belongs to the ATP-dependent AMP-binding enzyme family.

2-isopropylmalate synthase LeuA (alpha-isopropylmalate synthase) (alpha-IPM synthetase) (IPMS); Catalyzes the condensation of the acetyl group of acetyl-CoA with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form 3-carboxy-3- hydroxy-4-methylpentanoate (2-isopropylmalate).
