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

NIDE1624Putative HTH-type transcriptional regulator, rrf2 family; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator. (141 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.
  
  
 0.767
cysP
Sulfate/thiosulfate ABC transporter, periplasmic binding protein; Function of homologous gene experimentally demonstrated in an other organism; transporter.
  
    0.725
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.
  
  
 0.573
cysT
Sulfate/thiosulfate ABC transporter, permease protein CysT; Part of the ABC transporter complex (TC 3.A.1.6.1) involved in sulfate/thiosulfate import.
       0.516
NIDE1625
Protein of unknown function; No homology to any previously reported sequences.
       0.506
cysW
Sulfate/thiosulfate ABC transporter, permease protein CysW; Function of homologous gene experimentally demonstrated in an other organism; transporter.
     
 0.468
hscB
Co-chaperone protein HscB (Hsc20); Function of strongly homologous gene; factor.
  
  
 0.433
NIDE0407
Putative Sulfite reductase, contains SirA-like domain (modular protein); Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
  
 0.413
cysA
Sulfate/thiosulfate ABC transporter, ATP-binding protein; Part of the ABC transporter complex CysAWTP involved in sulfate/thiosulfate import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Sulfate/tungstate importer (TC 3.A.1.6) family.
