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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

iscSBPutative cysteine desulfurase IscS 2; Catalyzes the removal of elemental sulfur from cysteine to produce alanine (381 aa)    
Predicted Functional Partners:
thiI
Probable tRNA sulfurtransferase; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS

sufU
Zinc-dependent sulfurtransferase SufU; Its function is controversial. Has been generally assumed to be an iron-sulfur cluster assembly scaffold protein, but more recent evidence suggest it is a sulfurtransferase rather than a scaffold assembly protein. Has been shown to bind low levels of a labile, air-sensitive Fe-S cluster; this can be assembled under anaerobic conditions from FeCl(3) and Li(2)S. Has been shown to be able to transfer this Fe-S cluster to an acceptor protein. Stimulates the cysteine desulfurase activity of SufS, for which it acts as a second substrate. Alkylation elim [...]

moeB
Molybdopterin-synthase adenylyltransferase; Catalyzes the adenylation by ATP of the carboxyl group of the C-terminal glycine of sulfur carrier protein MoaD
  
 0.843
nifS
Putative cysteine desulfurase NifS; Catalyzes the removal of elemental sulfur from cysteine to produce alanine (By similarity). Seems to be required for NAD biosynthesis
  
  
 
0.835
yqeB
Uncharacterized protein YqeB; Evidence 4: Homologs of previously reported genes of unknown function
      
 0.833
iscSA
Putative cysteine desulfurase IscS 1; Catalyzes the removal of elemental sulfur from cysteine to produce alanine
  
  
 
0.820
braB
Branched-chain amino acid transport system carrier protein BraB; Component of the transport system for branched-chain amino acids (leucine, isoleucine and valine) Which is coupled to a proton motive force
     
 0.800
ykvY
Putative dipeptidase YkvY; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe : putative enzyme
  
  
 0.767
cysE
Serine acetyltransferase; Catalyzes the acetylation of serine by acetyl-CoA to produce O-acetylserine (OAS)
 
   
 0.763
moeA
Molybdopterin molybdenumtransferase; Catalyzes the insertion of molybdate into adenylated molybdopterin with the concomitant release of AMP; Belongs to the MoeA family
