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

Score
plcDRv1755c, (MT1799, MTCY28.21c), len: 280 aa. Probable plcD, phospholipase C 4 (fragment) (see citations below),highly similar to C-terminus of other phospholipases e.g. CQ50771|Rv2351c|PLCA|MTP40|MT2416|MTCY98.20c phospholipase C 1 from Mycobacterium tuberculosis (512 aa), FASTA score: (71.1% identity in 284 aa overlap); etc. Note that this ORF has been interrupted by insertion of IS6110 element. Belongs to the bacterial phospholipase C family. (280 aa)    
Predicted Functional Partners:
plcB
Membrane-associated phospholipase C 2 PlcB; Hydrolyzes sphingomyelin in addition to phosphatidylcholine. Probable virulence factor implicated in the pathogenesis of M.tuberculosis at the level of intracellular survival, by the alteration of cell signaling events or by direct cytotoxicity.

plcC
Rv2349c, (MT2414, MTCY98.18c), len: 508 aa. Probable plcC, phospolipase C 3 (see citations below), similar to other precursors of several phospolipases C e.g. P15713|PHLN_PSEAE|PA3319 non-hemolytic phospholipase C precursor from Pseudomonas aeruginosa (692 aa), FASTA scores: opt: 1013, E(): 9.3e-54, (38.85% identity in 525 aa overlap); P06200|PHLC_PSEAE hemolytic phospholipase C precursor from Pseudomonas aeruginosa (730 aa), FASTA scores: opt: 630, E(): 1.5e-30, (35.15% identity in 535 aa overlap); Q9S816|T12J13.18|T21P5.4 putative phospholipase from Arabidopsis thaliana (Mouse-ear cr [...]

plcA
Membrane-associated phospholipase C 1 PlcA (MTP40 antigen); Hydrolyzes sphingomyelin in addition to phosphatidylcholine. Probable virulence factor implicated in the pathogenesis of M.tuberculosis at the level of intracellular survival, by the alteration of cell signaling events or by direct cytotoxicity; Belongs to the bacterial phospholipase C family.

sapM
Acid phosphatase (acid phosphomonoesterase) (phosphomonoesterase) (glycerophosphatase); Virulence factor that plays an important role in blocking phagosome-lysosome fusion and thus participates in the intracellular survival of the pathogen. Acts as a phosphatase that dephosphorylates phosphatidylinositol 3-phosphate (PI3P), a membrane trafficking regulatory lipid essential for phagosomal acquisition of lysosomal constituents. Therefore, SapM eliminates PI3P from the phagosomal membrane by catalyzing its hydrolysis, and thus contributes to inhibition of phagosome maturation. Also interf [...]

psd
Possible phosphatidylserine decarboxylase Psd (PS decarboxylase); Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer).
     
  0.900
impA
Probable inositol-monophosphatase ImpA (imp); Catalyzes the dephosphorylation of inositol 1-phosphate (I-1- P) to yield free myo-inositol, a key metabolite in mycobacteria.
   
 
  0.900
pgsA2
Putative cardiolipin synthase; May catalyze the biosynthesis of cardiolipin from phosphatidylglycerol (PG) and CDP-diacylglycerol. Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
   
 
  0.900
dagK
Diacylglycerol kinase; Catalyzes the phosphorylation of diacylglycerol (DAG) into phosphatidic acid. Is involved in the biosynthesis of phosphatidylinositol mannosides (PIMs), probably via a role in the biosynthesis of phosphatidylinositol (PI), a PIM precursor, which is derived from phosphatidic acid (By similarity); Belongs to the diacylglycerol/lipid kinase family.
     
  0.900
suhB
Inositol-1-monophosphatase SuhB; Catalyzes the dephosphorylation of inositol 1-phosphate (I-1- P) to yield free myo-inositol, a key metabolite in mycobacteria. Is also able to hydrolyze a variety of polyol phosphates such as glucitol- 6-phosphate, inositol 2-phosphate (I-2-P), glycerol-2-phosphate, and 2'-AMP, albeit with reduced efficiency.

Rv1756c
Putative transposase; Rv1756c, (MTCY28.22c), len: 328 aa. Putative Transposase subunit for IS6110. Identical to many other M. tuberculosis IS6110 transposase subunits. The transposase described here may be made by a frame shifting mechanism during translation that fuses Rv1756c and Rv1757c, the sequence UUUUAAAG (directly upstream of Rv1756c) maybe responsible for such a frameshifting event (see McAdam et al., 1990). Start changed since first submission (+ 34 aa).
