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

ycbUPutative cysteine desulfurase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme. (370 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 [...]

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.
 
 
 0.863
sufC
Sulfur mobilizing ABC protein, ATPase; Evidence 2b: Function of strongly homologous gene; enzyme; Belongs to the ABC transporter superfamily. Ycf16 family.
 
  
 0.856
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.

yodT
Putative aminovalerate aminotransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
      
 0.759
yhxA
Hypothetical protein; Essential for glycerol catabolism; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
   
  
 0.699
fra
Frataxin; 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.
      
 0.681
lmrB
Efflux transporter; Proton-dependent transporter. May mediate the efflux of lincomycin; Belongs to the major facilitator superfamily. EmrB family.
   
  
 0.569
pcp
Pyrrolidone-carboxylate peptidase; Removes 5-oxoproline from various penultimate amino acid residues except L-proline; Belongs to the peptidase C15 family.
  
    0.559
iscSA
Cysteine desulfurase involved in tRNA thiolation; Catalyzes the removal of elemental sulfur from cysteine to produce alanine.
