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

Rv1279Rv1279, (MTCY50.03c), len: 528 aa. Probable dehydrogenase, FAD flavoprotein GMC oxidoreductase, similar to several e.g. dBETA_ECOLI|P17444 choline dehydrogenase from Escherichia coli (556 aa), FASTA scores, opt: 1047,E(): 0, (37.7% identity in 541 aa overlap). Similar to Rv0697 putative Mycobacterium tuberculosis GMC oxidoreductase. Contains PS00623 GMC oxidoreductases signature 1, and PS00624 GMC oxidoreductases signature 2. Belongs to the GMC oxidoreductases family. (528 aa)    
Predicted Functional Partners:
Rv1278
Hypothetical protein; Rv1278, (MTCY50.04c), len: 875 aa. Hypothetical unknown protein, possible coiled-coil regions, contains PS00017 ATP/GTP-binding site motif A. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

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.
   
 
  0.805
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.

plcD
Rv1755c, (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.
   
 
  0.800
qcrC
Probable ubiquinol-cytochrome C reductase QcrC (cytochrome C subunit); Cytochrome b subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of ubiquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
