Rv2624c, (MTCY01A10.08), len: 272 aa. Universal stress protein family protein, similar to several Streptomyces proteins e.g. Q9RIY5|SCJ1.29c hypothetical 30.1 KDA protein from Streptomyces coelicolor (283 aa),FASTA scores: opt: 260, E(): 5e-09, (32.05% identity in 290 aa overlap).

Conserved protein; Rv2627c, (MTCY01A10.05), len: 413 aa. Conserved protein. Some similarity in C-terminal part of O53697|Rv0293c|MTV035.21c hypothetical 44.0 KDA protein from Mycobacterium tuberculosis (400 aa), FASTA scores: opt: 392, E(): 1.9e-17, (31.1% identity in 299 aa overlap). Alternative nucleotide at position 2954439 (T->C; R104G) has been observed. Predicted possible vaccine candidate (See Zvi et al., 2008).

Universal stress protein family protein TB31.7; May play a role in the establishment of a persistent infection (latency) in the host, as strains without this gene are hypervirulent. Overexpression of the protein retards growth in culture; Glu-15 and Ala-117 mutant proteins which bind less ATP do not show this retardation, suggesting growth may be regulated through an ATP- dependent function.

Rv2625c, (MTCY01A10.07), len: 393 aa. Probable conserved transmembrane ala-, leu-rich protein, similar to many hypothetical or membrane proteins e.g. Q55518|Y528_SYNY3|SLL0528 potential integral membrane protein from Synechocystis sp. strain PCC 6803 (379 aa),FASTA scores: opt: 552, E(): 5.6e-26, (30.75% identity in 374 aa overlap); Q9RJ56|SCI41.35c hypothetical 39.8 KDA protein from Streptomyces coelicolor (374 aa), FASTA scores: opt: 419, E(): 5.7e-18, (31.6% identity in 383 aa overlap); CAC49448|SMB20925 conserved hypothetical membrane protein from Rhizobium meliloti (Sinorhizobium [...]

Probable nitrate reductase NarX; Does not seem to have nitrate reductase activity. In the N-terminal section; belongs to the nitrate reductase alpha subunit family. In the C-terminal section; belongs to the nitrate reductase gamma subunit family.

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 [...]

Two component transcriptional regulatory protein DevR (probably LuxR/UhpA-family); Member of the two-component regulatory system DevR/DevS (also called DosR/DosS) involved in onset of the dormancy response. Regulates an approximately 48-member regulon. When phosphorylated binds and activates the promoter of DevR regulon genes in response to hypoxia. The presence of target DNA increases stability of phospho-DevR in vitro. Activates its own transcription under hypoxic but not aerobic conditions, probably binds as a dimer to tandem binding sites within the devR and hspX promoters. Accepts [...]
