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 [...]

Rv3446c, (MTCY77.18c), len: 404 aa. Hypothetical unknown ala-, val-rich protein.

Rv2910c, (MTCY274.42c), len: 147 aa. Conserved hypothetical protein, showing some similarity with hypothetical proteins from other organisms e.g. Q9JN76|MMYY hypothetical 17.4 KDA protein from Streptomyces coelicolor (153 aa), FASTA scores: opt: 164, E(): 0.00026, (35.05% identity in 129 aa overlap); etc. Also some similarity with protein from Mycobacterium tuberculosis e.g. O07237|Rv0310c|MTCY63.15c (163 aa), FASTA scores: opt: 165,E(): 0.00023, (26.3% identity in 137 aa overlap); P96815|Rv0138|MTCI5.12 (167 aa), FASTA scores: opt: 132,E(): 0.048, (30.25% identity in 109 aa overlap); etc.

Possible triacylglycerol synthase (diacylglycerol acyltransferase); Upon expression in E.coli functions very weakly as a triacylglycerol synthase, making triacylglycerol (TG) from diolein and long-chain fatty acyl-CoA. Has no wax synthase activity; Belongs to the long-chain O-acyltransferase family.

Possible exported protein; GDSL lipase that catalyzes the hydrolysis of p-nitrophenyl (pNP) esters. pNP-decanoate (C10) is the preferred substrate. It can also use pNP-octanoate (C8), pNP-dodecanoate (C12) and pNP- tetradecanoate (C14). Has lower activity with pNP-butyrate (C4), pNP- palmitate (C16) and pNP-stearate (C18). Does not show phospholipase A1 activity. Might help bacteria to utilize available lipids for its growth as well as provide resistance to various intracellular stresses by cell wall modulation resulting in enhanced intracellular survival.
