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

Rv0792c
Probable transcriptional regulatory protein (probably GntR-family); Rv0792c, (MTV042.02c), len: 269 aa. Probable transcriptional regulator, GntR-family, similar to many others of GntR family e.g. BSUB0018_189|Z99121 from Bacillus subtilis (243 aa), FASTA scores: opt: 367, E(): 1.5e-17, (32.1% identity in 246 aa overlap); P31453|YIDP_ECOLI from Escherichia coli (238 aa), FASTA scores: opt: 236, E(): 8.8e-09, (26.4% identity in 235 aa overlap); etc.

dgt
Rv2344c, (MT2409, MTCY98.13c), len: 431 aa. Probable dgt, deoxyguanosine triphosphate triphosphohydrolase,equivalent to Q9CCG3|DGT|ML0831 putative deoxyguanosine triphosphate triphosphohydrolase from Mycobacterium leprae (429 aa), FASTA scores: opt: 2316, E(): 1.6e-137, (83.85% identity in 421 aa overlap); and O52199|DGTP_MYCSM|AF027507_2 deoxyguanosinetriphosphate triphosphohydrolase from Mycobacterium smegmatis (428 aa),FASTA scores: opt: 1991, E(): 3.4e-117, (73.5% identity in 422 aa overlap). Also highly similar or similar to several deoxyguanosine triphosphate hydrolases e.g. Q9L2 [...]

ctaD
Probable cytochrome C oxidase polypeptide I CtaD (cytochrome AA3 subunit 1); Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B (By similarity).
  
   0.787
qcrB
Probable ubiquinol-cytochrome C reductase QcrB (cytochrome B 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. The cytochrome b subunit contains two ubiquinol reactive sites: the oxidation (QP) site and the reduction (QN) site.
  
   0.786
ctaC
Probable transmembrane cytochrome C oxidase (subunit II) CtaC; Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B) (By similarity).
  
   0.785
qcrA
Probable rieske iron-sulfur protein QcrA; Iron-sulfur 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 menaquinol 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.
