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

Possible fdhF,formate dehydrogenase, highly similar to others formate dehydrogenases and prokaryotic molybdopterin-containing oxidoreductases e.g. Q9S2J9|SC7H2.18 putative formate dehydrogenase from Streptomyces coelicolor (759 aa), FASTA scores: opt: 3038, E(): 2.7e-180, (59.7% identity in 767 aa overlap); Q9HU08|PA5181 probable oxidoreductase from Pseudomonas aeruginosa (773 aa), FASTA scores: opt: 2560,E(): 1.1e-150, (53.2% identity in 761 aa overlap); P78160 formate dehydrogenase a chain (fragment) from Es [...] (779 aa)    
Predicted Functional Partners:
fdhD
Possible FdhD protein homolog; Required for formate dehydrogenase (FDH) activity. Acts as a sulfur carrier protein that transfers sulfur from IscS to the molybdenum cofactor prior to its insertion into FDH. Belongs to the FdhD family.
 
  
 0.988
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.

tuf
Probable iron-regulated elongation factor TU Tuf (EF-TU); This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.

Rv0218
Rv0218, (MTCY08D5.13), len: 442 aa. Probable conserved transmembrane protein, some similarity with sulfite oxidases e.g. SUOX_HUMAN|P51687 sulfite oxidase precursor (488 aa), FASTA scores: opt: 153, E(): 0.0087,(28.6% identity in 161 aa overlap); and with some nitrate reductases e.g. NIA_FUSOX|P39863 nitrate reductase (NADPH) (905 aa), FASTA scores: opt: 143, E(): 0.06, (29.3% identity in 92 aa overlap). Also similar to BSUB0017_86 from Mycobacterium tuberculosis.

Conserved protein; Rv2901c, (MTCY274.32c), len: 101 aa. Conserved protein, very equivalent to O33023|ML1610|MLCB250.41 hypothetical 12.3 KDA protein from Mycobacterium leprae (101 aa), FASTA scores: opt: 658, E(): 2.6e-43, (99.0% identity in 101 aa overlap).

pncB1
Nicotinic acid phosphoribosyltransferase PncB1; Involved in the Preiss-Handler pathway, which is a recycling route that permits the salvage of free nicotinamide (NM) and nicotinic acid (Na) involved in the NAD biosynthesis. Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP. It is not able to use nicotinamide. PncB1 contributes to basal NAD level.

Probable adenylyltransferase/sulfurtransferase MoeZ; Catalyzes the conversion of the sulfur carrier protein CysO to CysO-thiocarboxylate. The reaction is thought to proceed in two steps: first, ATP-dependent activation of CysO as acyl-adenylate (CysO- COOAMP), followed by sulfur transfer to give CysO-thiocarboxylate (CysO-COSH) (Probable). The sulfur source is unknown.
