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

sufSSelenocysteine lyase; Cysteine desulfurases mobilize the sulfur from L-cysteine to yield L-alanine, an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Component of the suf operon, which is activated and required under specific conditions such as oxidative stress and iron limitation. Acts as a potent selenocysteine lyase in vitro, that mobilizes selenium from L- selenocysteine. Selenocysteine lyase activity is however unsure in vivo. (406 aa)    
Predicted Functional Partners:
sufB
Putative ABC transporter; Similar to E. coli orf, hypothetical protein (AAC74753.1); Blastp hit to AAC74753.1 (508 aa), 96% identity in aa 14 - 508.
 
 0.999
sufC
Putative transport protein; ABC superfamily (atp_bind); similar to E. coli putative ATP-binding component of a transport system (AAC74752.1); Blastp hit to AAC74752.1 (248 aa), 92% identity in aa 1 - 248.
  
 0.999
sufD
Iron-sulfur component of FhuF stability protein; Similar to E. coli orf, hypothetical protein (AAC74751.1); Blastp hit to AAC74751.1 (423 aa), 79% identity in aa 1 - 421.
 
 0.999
ynhA
Putative SufE protein; Participates in cysteine desulfuration mediated by SufS. Cysteine desulfuration mobilizes sulfur from L-cysteine to yield L- alanine and constitutes an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Functions as a sulfur acceptor for SufS, by mediating the direct transfer of the sulfur atom from the S-sulfanylcysteine of SufS, an intermediate product of cysteine desulfuration process; Belongs to the SufE family.
 
 0.999
sufA
Putative HesB-like domain protein; Similar to E. coli orf, hypothetical protein (AAC74754.1); Blastp hit to AAC74754.1 (122 aa), 84% identity in aa 1 - 122; Belongs to the HesB/IscA family.
 
 0.966
nifU
NifU homolog; 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.
  
 0.962
ygdK
Putative SufE protein probably involved in Fe-S center assembly; Similar to E. coli orf, hypothetical protein (AAC75853.1); Blastp hit to AAC75853.1 (147 aa), 88% identity in aa 1 - 144.
 
 0.956
trxB
Similar to E. coli thioredoxin reductase (AAC73974.1); Blastp hit to AAC73974.1 (321 aa), 96% identity in aa 1 - 320.
 
 
 0.921
selD
Selenophosphate synthase; Synthesizes selenophosphate from selenide and ATP.
 
 
 0.917
metB
Similar to E. coli cystathionine gamma-synthase (AAC76921.1); Blastp hit to AAC76921.1 (386 aa), 96% identity in aa 1 - 386.
