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

Sfri_2425Transcriptional regulator, BadM/Rrf2 family; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins. (153 aa)    
Predicted Functional Partners:
Sfri_2423
FeS cluster assembly scaffold 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.
 
  
 0.961
hscB
Co-chaperone Hsc20; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family.
 
  
 0.922
iscS
Cysteine desulfurase IscS; 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.
  
 0.921
Sfri_2422
Iron-sulfur cluster assembly protein IscA; Is able to transfer iron-sulfur clusters to apo-ferredoxin. Multiple cycles of [2Fe2S] cluster formation and transfer are observed, suggesting that IscA acts catalytically. Recruits intracellular free iron so as to provide iron for the assembly of transient iron-sulfur cluster in IscU in the presence of IscS, L-cysteine and the thioredoxin reductase system; Belongs to the HesB/IscA family.

Sfri_2092
PFAM: aminotransferase, class V; KEGG: ecu:ECU11_1770 cysteine desulfurase.
 
  
 0.813
nfuA
HesB/YadR/YfhF-family protein; Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S cluster, can transfer this cluster to apoproteins, and thereby intervenes in the maturation of Fe/S proteins. Could also act as a scaffold/chaperone for damaged Fe/S proteins.
  
  
 0.703
Sfri_2419
TIGRFAM: ferredoxin, 2Fe-2S type, ISC system; PFAM: ferredoxin; KEGG: son:SO2269 ferredoxin, 2Fe-2S.
  
  
 0.658
Sfri_2426
TIGRFAM: serine O-acetyltransferase; KEGG: son:SO2262 serine acetyltransferase.
 
   
 0.616
Sfri_3699
PFAM: globin; oxidoreductase FAD/NAD(P)-binding domain protein; Oxidoreductase FAD-binding domain protein; KEGG: ppu:PP0808 flavohemoprotein; Belongs to the globin family.
     
 0.496
Sfri_3608
PFAM: ferredoxin; oxidoreductase FAD/NAD(P)-binding domain protein; Oxidoreductase FAD-binding domain protein; KEGG: son:SO1364 iron-sulfur cluster-binding protein.
