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.

PLU3283Putative aminotransferase NifS, class V; 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:
CV1093
Putative NifU-related 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
SIRA
Conserved hypothetical protein; Sulfur carrier protein which probably makes part of a sulfur- relay system; Belongs to the sulfur carrier protein TusA family.
 
 
 0.996
HSCB
Putative chaperone protein HscB; 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.
 
 0.991
STY2784
Putative ferredoxin; Predicted by orpheus program; predicted by glimmer program.
 
 0.991
thiI
Putative thiamin biosynthesis 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.
  
 0.990
STY2790
Hypothetical transcriptional regulator; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins.
  
 0.989
STM2541
Putative hesB family protein; 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.
 
 
 0.985
BT0174
Hypothetical protein; Predicted by orpheus program; predicted by glimmer program.
  
 0.984
PM1557
Conserved hypothetical 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.
  
 0.973
C0911
Putative molybdopterin biosynthesis MoeB protein; Predicted by orpheus program; predicted by glimmer program.
   
 0.972
