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.

fraFrataxin; Possible global iron distributor for the cell. Promotes the biosynthesis of iron-sulfur clusters by delivering Fe to the iron- sulfur cluster assembly scaffold protein SufU. In the presence of SufS and L-cysteine reconstitutes Fe-S clusters on SufU, which when further incubated with apo-aconitase (citB) reconstitutes aconitase activity. Able to reconstitute an Fe-S cluster on Thermotoga maritima IscU. (123 aa)    
Predicted Functional Partners:
sufU
Iron-sulfur cluster assembly scaffold protein; 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. Alkyl [...]

iscSA
Cysteine desulfurase involved in tRNA thiolation; Catalyzes the removal of elemental sulfur from cysteine to produce alanine.
      
 0.745
fer
Ferredoxin; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. This ferredoxin may act as a phosphodonor to cytochrome P450 BioI.
   
  
 0.719
nifS
Putative desulfurase involved in iron-sulfur clusters for NAD biosynthesis; Catalyzes the removal of elemental sulfur from cysteine to produce alanine (By similarity). Seems to be required for NAD biosynthesis.
      
 0.715
iscSB
Cysteine desulfurase; Catalyzes the removal of elemental sulfur from cysteine to produce alanine.
      
 0.680
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX; Belongs to the ferrochelatase family.
      
 0.654
ydeD
Putative permease; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
      
 0.640
sufB
FeS cluster formation protein; The SufBCD complex acts synergistically with SufE to stimulate the cysteine desulfurase activity of SufS. The SufBCD complex contributes to the assembly or repair of oxygen-labile iron-sulfur clusters under oxidative stress. May facilitate iron uptake from extracellular iron chelators under iron limitation (By similarity). Belongs to the UPF0051 (ycf24) family.
      
 0.633
sufD
FeS assembly protein SufD; The SufBCD complex acts synergistically with SufE to stimulate the cysteine desulfurase activity of SufS. The SufBCD complex contributes to the assembly or repair of oxygen-labile iron-sulfur clusters under oxidative stress. May facilitate iron uptake from extracellular iron chelators under iron limitation (By similarity). Belongs to the UPF0051 (ycf24) family.

ycbU
Putative cysteine desulfurase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
