Rv1120c, (MTCY22G8.09c), len: 164 aa. Conserved hypothetical protein, some similarity at C-terminus to Mycobacterium tuberculosis hypothetical proteins e.g. Rv1890c|MTCY180.28 (462 aa), FASTA scores: opt: 187, E(): 2.2e-05, (36.6% identity in 93 aa overlap) and Rv2488c|YZ19_MYCTU|Q10551 (285 aa), FASTA scores: opt: 156,E(): 0.00074, (32.7% identity in 107 aa overlap).

Two component sensor histidine kinase DosT; Interacts with the two-component regulatory system DevR/DevS (DosR/DosS) involved in onset of the dormancy response. Required for full induction of the DevR (DosR) regulon; required during early adaptation to anaerobiosis, to start induction of the DevR regulon. May act as a direct hypoxia/oxygen sensor. O(2) acts as a switch, with the Fe(2+)-O(2)-bound protein inactive in autophosphorylation. Autophosphorylates under anaerobic but not aerobic conditions, binding of NO or CO has no effect on autophosphorylation. Binds a number of gases; O(2), [...]

Two component sensor histidine kinase DevS; Member of the two-component regulatory system DevR/DevS (DosR/DosS) involved in onset of the dormancy response. Regulates an approximately 48-member regulon. Required for full induction of the DevR (DosR) regulon; acts later than DosT to positively regulate expression of the DevR regulon during adaptation to anaerobiosis. Characterized as an oxygen sensor; O(2) acts as a switch, with O(2)-bound Fe(2+) protein inactive in autophosphorylation. Has also been suggested to act as a redox sensor, or perhaps as a dual oxygen/redox sensor. Autophosph [...]

Probable lppW,conserved ala-rich lipoprotein, with slight similarity to beta-lactamases and hypothetical proteins e.g. Q9S1P7|SCJ9A.23 hypothetical 36.3 KDA protein from Streptomyces coelicolor (336 aa), FASTA scores: opt: 222,E(): 2.8e-06, (25.5% identity in 298 aa overlap); O69914|SC3C8.01 putative secreted protein from Streptomyces coelicolor (302 aa), FASTA scores: opt: 201, E(): 5.1e-05,(24.9% identity in 257 aa overlap); P14559|BLAC_STRAL beta-lactamase precursor from Streptomyces albus G (314 aa), FASTA scores: opt: 113, E(): 3.3, (25.2% identi [...]

Possible two component sensor kinase; Member of the two-component regulatory system NarS/NarL involved in gene expression during aerobic nitrate metabolism. Plays therefore a crucial role in anaerobic survival of mycobacteria in host. 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 NarL. In turn, NarL binds to the upstream promoter regions of target genes to regulate their expression during aerobic nitrate metabolism.

Rv0941c, (MTCY10D7.33), len: 257 aa. Conserved hypothetical protein, showing some similarity with parts of several hypothetical proteins from Streptomyces coelicolor e.g. AL035161|SC9C7_20 (860 aa), FASTA scores: opt: 197,E(): 2.6e-05, (34.2% identity in 114 aa overlap).
