Probable peroxiredoxin AhpE; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. May represent an important antioxidant defense against cytotoxic peroxides, especially peroxynitrite, which can be formed by activated macrophages during infection. Belongs to the peroxiredoxin family. AhpE subfamily.

Rv2235, (MTCY427.16), len: 271 aa. Probable conserved transmembrane protein (see Miller & Shinnick 2001); hydrophobic regions near N- and C-terminus. Similar to conserved membrane proteins in other Actinomycetes. Equivalent to Mycobacterium leprae. ML1644 (270 aa). FASTA scores: opt: 1357, E(): 1.2e-72; 74.170% identity in 271 aa overlap T44717|3150235|CAA19213.1|AL023635 13093419|CAC30595.1|AL583922. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al.,2004).

Conserved protein; Rv0365c, (MTCY13E10.27c), len: 376 aa (start uncertain). Conserved protein (see citation below), very similar to G388212|CAA35191.1, a truncated ORF immediately upstream of the Corynebacterium glutamicum fda gene encoding fructose-1,6-biphosphate aldolase (304 aa), FASTA scores: E(): 7.1e-19, (42.2% identity in 296 aa overlap).

Rv2699c, (MTCY05A6.20c), len: 100 aa. Conserved hypothetical protein, very equivalent to Q49990|ML1026|U1764J hypothetical protein from Mycobacterium leprae (100 aa), FASTA scores: opt: 632, E(): 7.7e-36, (96.0% identity in 100 aa overlap). Also highly similar to O54130|SC2E9.05 hypothetical 11.0 KDA protein from Streptomyces coelicolor (98 aa), FASTA scores: opt: 465, E(): 1.1e-24, (71.45% identity in 98 aa overlap).

Ribosome recycling factor Frr (ribosome releasing factor) (RRF); Responsible for the release of ribosomes from messenger RNA at the termination of protein biosynthesis. May increase the efficiency of translation by recycling ribosomes from one round of translation to another; Belongs to the RRF family.

Probable two-component system transcriptional regulator; Member of the two-component regulatory system PdtaR/PdtaS.

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 [...]

GCN5-related N-acetyltransferase; Rv2867c, (MTV003.13c), len: 284 aa. Probable acetyltransferase. Contains GNAT (Gcn5-related N-acetyltransferase) domain in C-terminal part. See Vetting et al. 2005. Similar to others e.g. Q9KYR8|SC5H4.21 hypothetical 31.3 KDA protein from Streptomyces coelicolor (287 aa), FASTA scores: opt: 798, E(): 2.4e-45, (47.95% identity in 269 aa overlap).

Conserved protein; Binds to RNA polymerase (RNAP), stimulating and stabilizing the formation of stable RNAP promoter complexes up to 2-fold from principal sigma factor SigA-dependent but not alternative sigma factor SigF-dependent promoters. Increases the affinity of core RNAP for SigA, increasing the transcriptional activity of RNAP. Unlike the case in M.smegmatis or S.coelicolor, has no effect on rifampicin inhibition of transcription. Has no effect on E.coli RNAP. Belongs to the RNA polymerase-binding protein RbpA family.
