Conserved hypothetical protein; Degradation of inorganic polyphosphates (polyP). Releases orthophosphate processively from the ends of the polyP chain. Prefers short-chain length polyphosphates as substrates. Can also hydrolyze ATP and ADP substrates, but lacks GTPase activity. Cannot hydrolyze pppGpp to ppGpp; Belongs to the GppA/Ppx family.

Conserved protein; Degradation of inorganic polyphosphates (polyP). Releases orthophosphate processively from the ends of the polyP chain. Prefers long-chain length polyphosphates as substrates (By similarity). Can also hydrolyze ATP and ADP substrates, but lacks GTPase activity. Cannot hydrolyze pppGpp to ppGpp. Belongs to the GppA/Ppx family.

Probable glutamine amidotransferase SnoP; Catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the biosynthesis of pyridoxal 5'-phosphate. The resulting ammonia molecule is channeled to the active site of PdxS.

Possible pyridoxine biosynthesis protein SnzP; Catalyzes the formation of pyridoxal 5'-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by the PdxT subunit. Can also use ribulose 5- phosphate and dihydroxyacetone phosphate as substrates, resulting from enzyme-catalyzed isomerization of RBP and G3P, respectively. Belongs to the PdxS/SNZ family.

Polyphosphate kinase Ppk2 (polyphosphoric acid kinase); Uses inorganic polyphosphate (polyP) as a donor to convert GDP to GTP. In addition, modulates nucleotide triphosphate synthesis catalyzed by the nucleoside diphosphate kinase (Ndk) in favor of GTP production over CTP or UTP. Plays an important role in survival of M.tuberculosis in macrophages.

Rv2605c, (MTCY01A10.28), len: 281 aa. Probable tesB2, acyl-CoA thioesterase II, highly similar to others e.g. Q98EG9|MLL4250 from Rhizobium loti (Mesorhizobium loti) (286 aa), FASTA scores: opt: 563, E(): 3.9e-29,(47.75% identity in 287 aa overlap); CAC47767 from Rhizobium meliloti (Sinorhizobium meliloti) (294 aa), FASTA scores: opt: 553, E(): 1.8e-28, (49.3% identity in 280 aa overlap); P23911|TESB_ECOLI|B0452 from Escherichia coli strain K12 (285 aa), FASTA scores: opt: 487, E(): 3.1e-24,(41.9% identity in 277 aa overlap); etc. Also similar to O06135|TESB1|Rv1618|MTCY01B2.10 acyl-Co [...]

Polyphosphate glucokinase PpgK (polyphosphate-glucose phosphotransferase); Catalyzes the phosphorylation of glucose using polyphosphate or ATP as the phosphoryl donor. Polyphosphate, rather than ATP, seems to be the major phosphate donor for the enzyme in M.tuberculosis (By similarity); Belongs to the ROK (NagC/XylR) family.

30S ribosomal protein S1 RpsA; Binds mRNA, facilitating recognition of most mRNAs by the 30S ribosomal subunit during translation initiation (By similarity). Probably plays a role in trans-translation; binds tmRNA (the product of the ssrA gene). In trans-translation Ala- aminoacylated transfer-messenger RNA (tmRNA, product of the ssrA gene; the 2 termini fold to resemble tRNA(Ala) while it encodes a short internal open reading frame (the tag peptide)) acts like a tRNA, entering the A-site of the ribosome and displacing the stalled mRNA (which is subsequently degraded). The ribosome the [...]

Polyphosphate kinase PPK (polyphosphoric acid kinase) (ATP-polyphosphate phosphotransferase); Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP); Belongs to the polyphosphate kinase 1 (PPK1) family.
