STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

lprJProbable lipoprotein LprJ; Overexpression induces expression of sensor protein kdpD gene at low K(+) concentrations (0 and 250 uM, tested in M.smegatis). (127 aa)    
Predicted Functional Partners:
kdpD
Probable sensor protein KdpD; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. 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 KdpE in response to environmental signals such as low levels of potassium ion, osmotic imbalance, acid and nutrient stresses. In turn, KdpE binds to the upstream promoter regions of target genes to positively regulate their expression.

Rv1691
Rv1691, MTCI125.13, len: 250 aa. Conserved hypothetical protein, similar to Q9S210|SCI51.30C|AL109848 Hypothetical protein from Streptomyces coelicolor (210 aa),FASTA score: opt: 556, E(): 6.4e-27, (50.6% identity in 180 aa overlap).
  
    0.744
Rv1692
Probable phosphatase; Glycerol-phosphate phosphatase with a preference for D- glycerol 3-phosphate (sn-glycerol 1-phosphate) over L-glycerol 3- phosphate (sn-glycerol 3-phosphate). Is the final enzyme involved in the recycling/catabolism of glycerophospholipid polar heads. To a lesser extent, is also able to act on glycerol 2-phosphate and D- ribulose 5-phosphate, but cannot use D-glyceraldehyde 3-phosphate, dihydroxyacetone-phosphate, UMP or GMP as substrates. Belongs to the HAD-like hydrolase superfamily.
       0.741
Rv1693
Rv1693, (MTCI125.15), len: 58 aa. Conserved hypothetical protein, shows some similarity to AL583921 hypothetical protein from Mycobacterium leprae (61 aa). Probable coiled-coil from aa 30 to 58. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).
  
    0.735
ppnK
Inorganic polyphosphate/ATP-NAD kinase PpnK (poly(P)/ATP NAD kinase); Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP. It can use ATP and other nucleoside triphosphates as well as inorganic polyphosphate (poly(P)) as a source of phosphorus.
  
    0.734
tlyA
2'-O-methyltransferase TlyA; Acts as a host evasion factor, that significantly contributes to the pathogenesis of M.tuberculosis by modulating adaptive immune responses by inhibiting host-protective Th1 and Th17 cytokine responses as well as autophagy. Catalyzes the 2'-O-methylation at nucleotides C1409 in 16S rRNA and C1920 in 23S rRNA. Is likely involved in ribosomal biogenesis. Also exhibits hemolytic activity in vitro, by binding with and oligomerizing into host cell membranes. Belongs to the TlyA family.
  
    0.732
spmT
Probable exported protein; Catalyzes the cleavage of sphingomyelin, a major lipid in eukaryotic cells, into ceramide and phosphocholine, which are then utilized by M.tuberculosis as carbon, nitrogen and phosphorus sources, respectively. Thus, enables M.tuberculosis to utilize sphingomyelin as a source of several essential nutrients for intracellular growth during infection. Furthermore, lyses erythrocytes and constitutes the main hemolytic factor of M.tuberculosis.
   
    0.687
recN
Probable DNA repair protein RecN (recombination protein N); May be involved in recombinational repair of damaged DNA.
  
    0.668
lprF
Probable conserved lipoprotein LprF; Might be involved in transporting short diacylated glycolipids to the cell outer membrane (By similarity). Overexpression induces expression of sensor protein kdpD gene at low K(+) concentrations (0 and 250 uM, tested in M.smegatis). Belongs to the LppX/LprAFG lipoprotein family.

lpqA
Rv3016, (MTV012.30), len: 209 aa. Probable lpqA,lipoprotein. Contains signal sequence and appropriately positioned PS00013 Prokaryotic membrane lipoprotein lipid attachment site.
