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

iscSCysteine 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. (404 aa)    
Predicted Functional Partners:
iscU
Iron-sulfur cluster assembly scaffold protein; 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.
 
 0.999
nifU
Nitrogen fixation Fe-S cluster scaffold protein; Involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
 
 0.998
thiI
Thiamine biosynthesis/tRNA modification protein ThiI; 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.
  
 0.989
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.
 
 
 0.977
moeB2
Molybdopterin biosynthesis protein, MoeB.
   
 0.974
tusA
SirA-like protein, tRNA 2-thiouridine synthesizing protein, TusA; Sulfur carrier protein which probably makes part of a sulfur- relay system; Belongs to the sulfur carrier protein TusA family.
   
 0.974
cyaY
Frataxin-like protein; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
  
 0.973
rhdA
Rhodanese.
  
 0.972
fdx
Isc ferredoxin.
 
 0.966
ACO80277.1
Molybdopterin biosynthesis protein MoeB.
   
 0.962
