Rv2303c, (MTCY339.06, MT2360), len: 307 aa. Probable antibiotic-resistance protein, with some similarity to Q54229|G153373 macrotetrolide antibiotic-resistance protein (NONR) from Streptomyces griseus (347 aa) (see Plater and Robinson, 1992), FASTA scores: opt: 438, E(): 3.1e-21,(33.2% identity in 226 aa overlap); and other hypothetical proteins e.g. P95886 ORF C02006 from Sulfolobus solfataricus (269 aa), FASTA scores: opt: 252, E(): 3.5e-09, (25.5% identity in 286 aa overlap); etc. Also similar to Mycobacterium tuberculosis Rv3510c|O53555|MTV023.17. Note that the protein Q9XDF3|NONC [...]

Hypothetical protein; Rv1907c, (MTCY180.11), len: 215 aa. Hypothetical unknown protein. Similar to Q50763 Ethyl methane sulphonate resistance protein from Mycobacterium tuberculosis (168 aa), FASTA scores: opt: 638, E(): 0, (69.7% identity in 152 aa overlap). Downstream of a cloned katG gene (EMBL:mtkatg). Differences are due to frameshift errors in the EMBL sequence and the use of an earlier start codon. Alternative nucleotide at position 2153410 (a->G; V158A) has been observed.

Rv1877, (MTCY180.41c), len: 687 aa. Probable conserved integral membrane protein, part of major facilitator superfamily (MFS), similar to many antibiotic and drug efflux proteins. Similar to e.g. Q56175 TU22 dTDP-glucose dehydrtatase from Streptomyces violaceoruber (557 aa), FASTA scores: opt: 895, E(): 0, (34.7% identity in 528 aa overlap). Also similar to Mycobacterium tuberculosis relatives protein, include Rv3728, Rv3239c,Rv2846c, etc. Contains PS00217 Sugar transport proteins signature 2 (PS00217).

Probable holliday junction DNA helicase RuvA; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing. RuvA stimulates, in the presence of DNA, the weak ATPase activity of RuvB.

Rv1841c, (MTCY359.32), len: 345 aa. Conserved hypothetical membrane protein. Some similarity to O07585|YHDP_BACSU hypothetical 49.9 kDa protein from Bacillus subtilis (444 aa), FASTA scores: opt: 620, E(): 0,(31.1% identity in 350 aa overlap). Also similar to other Mycobacterium tuberculosis proteins e.g. Rv1842c, Rv2366c.

Two component sensor kinase MprB; Member of the two-component regulatory system MprB/MprA which contributes to maintaining a balance among several systems involved in stress resistance and is required for establishment and maintenance of persistent infection in the host. In response to environmental signals MprB acts as both a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to MprA, and a protein phosphatase that dephosphorylates phospho-MprA. MprB/MprA is involved in regulation of numerous stress-responsive genes, includin [...]

Outer membrane protein A OmpA; Probably plays a role in ammonia secretion that neutralizes the medium at pH 5.5, although it does not play a direct role in ammonia transport. The OmpA-like domain (196-326) binds M.tuberculosis peptidoglycan. Overexpression in M.bovis or M.smegmatis gives channels with average conductance value of 1,600 +/- 100 pS, but this may not be physiologically relevant; Belongs to the outer membrane OOP (TC 1.B.6) superfamily. ArfA family.
