Rv2133c, (MTCY270.35), len: 262 aa. Conserved hypothetical protein. Function: unknown but equivalent to hypothetical Mycobacterium leprae protein, Q49774. FASTA best: Q49774 B2126_C1_150 (262 aa) opt: 1447, E(): 0; (79.0% identity in 262 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Rv1383, (MTCY02B12.17), len: 376 aa. Probable carA,Carbamoyl-phosphate synthase small chain, similar to many e.g. CARA_ECOLI|P00907 carbamoyl-phosphate synthase small chain from Escherichia coli (382 aa), FASTA scores: opt: 796, E(): 0, (45.5% identity in 382 aa overlap). Contains PS00442 Glutamine amidotransferases class-I active site. The gatase domain belongs to type-1 glutamine amidotransferases. subunit: composed of two chains; the small (or glutamine) chain promotes the hydrolysis of glutamine to ammonia, which is used by the large (or ammonia) chain to synthesize carbamoyl phosphate.

Decaprenyl-phosphate N-acetylglucosaminephosphotransferase; Involved in the biosynthesis of the disaccharide D-N- acetylglucosamine-L-rhamnose which plays an important role in the mycobacterial cell wall as a linker connecting arabinogalactan and peptidoglycan via a phosphodiester linkage. Catalyzes the transfer of the N-acetylglucosamine-1-phosphate (GlcNAc-1P) moiety from UDP-GlcNAc onto the carrier lipid decaprenyl phosphate (C50-P), yielding GlcNAc- pyrophosphoryl-decaprenyl (GlcNAc-PP-C50).

PASTA domain-containing protein; Rv3682, (MTV025.030), len: 810 aa. Probable ponA2,penicillin-binding protein (class A), bienzymatic membrane-associated protein with transglycosylase and transpeptidase activities. Almost identical to Q9CB85|PON1|ML2308 penicillin binding protein (class A) from Mycobacterium leprae (803 aa) FASTA scores: opt: 4743,E(): 3.3e-217, (87.7% identity in 806 aa overlap); or P72351|PON1|PBP1 high-molecular-mass class a penicillin binding protein from Mycobacterium leprae Cosmid B577 (821 aa), FASTA scores: opt: 4547, E(): 6.3e-208, (88.05% identity in 769 aa ov [...]

Long (C50) chain Z-isoprenyl diphosphate synthase (Z-decaprenyl diphosphate synthase); Catalyzes the sequential condensation of isopentenyl diphosphate (IPP) in the cis configuration with (2Z,6E)-farnesyl diphosphate (Z-FPP or EZ-FPP) generating the 50 carbon product trans,polycis-decaprenyl diphosphate. When (2E,6E)-farnesyl diphosphate (E-FPP or EE-FPP) is used in vitro, both primary products decaprenyl diphosphate and (2E,6E,10E)-geranylgeranyl diphosphate (EEE-GGPP) are synthesized. M.tuberculosis does not synthesize (2E,6E,10Z)- geranylgeranyl diphosphate (EEZ-GGPP) and heptapreny [...]

Monophosphatase CysQ; Phosphatase with a broad specificity. Its primary physiological function is to dephosphorylate 3'-phosphoadenosine 5'- phosphate (PAP) and 3'-phosphoadenosine 5'-phosphosulfate (PAPS). Thus, plays a role in mycobacterial sulfur metabolism, since it can serve as a key regulator of the sulfate assimilation pathway by controlling the pools of PAP and PAPS in the cell. To a lesser extent, is also able to hydrolyze inositol 1-phosphate (I-1-P), fructose 1,6-bisphosphate (FBP) (to fructose 6-phosphate (F-6-P)) and AMP in vitro, but this might not be significant in vivo.
