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

fdxB2Fe-2S ferredoxin; Function of strongly homologous gene; carrier. (138 aa)    
Predicted Functional Partners:
iscS
Cysteine desulfurase; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
 
 0.986
iscU
Iron-sulfur cluster assembly protein IscU; A scaffold on which IscS assembles Fe-S clusters. It is likely that Fe-S cluster coordination is flexible as the role of this complex is to build and then hand off Fe-S clusters.
 
 0.980
nuoCD
NADH-quinone oxidoreductase, subunits C and D; Function of homologous gene experimentally demonstrated in an other organism; enzyme; In the N-terminal section; belongs to the complex I 30 kDa subunit family.
  
 
 0.975
NIDE2455
Putative Ferredoxin-NADP(+) reductase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
    
 0.936
gltD
Glutamate synthase, beta subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
    
 0.936
cyp
Cytochrome P450; Function of strongly homologous gene; enzyme; Belongs to the cytochrome P450 family.
  
 0.901
iscX
Iron-sulfur cluster assembly protein IscX; Function of strongly homologous gene; factor.
 
  
 0.900
hscB
Co-chaperone protein HscB (Hsc20); Function of strongly homologous gene; factor.
 
  
 0.895
nuoH
NADH-quinone oxidoreductase, membrane subunit H; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. This subunit may bind ubiquinone.

NIDE3565
Putative Ferredoxin-thioredoxin reductase, catalytic subunit; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
