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

nifSCysteine desulfurase; Identified by similarity to SP:Q43884; match to protein family HMM PF00266. (382 aa)    
Predicted Functional Partners:
MCA2088
Conserved hypothetical protein; Identified by similarity to GP:17427822; match to protein family HMM PF01206; Belongs to the sulfur carrier protein TusA family.
   
 0.975
MCA2211
Identified by match to protein family HMM PF00899; match to protein family HMM PF05237.
   
 0.972
MCA0988
NifU family protein; Identified by similarity to SP:P77310; match to protein family HMM PF01592; match to protein family HMM TIGR01994.
  
 0.962
MCA0248
NifU family 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.
 
 0.960
MCA2883
Rrf2 family protein; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins.
 
  
 0.945
sseA
Mercaptopyruvate sulfurtransferase; Identified by similarity to GP:6009981; match to protein family HMM PF00581.
   
 0.913
iscS
Cysteine desulfurase; 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.

MCA0239
Putative nitrogen fixation protein nifQ; Identified by similarity to SP:P11068; match to protein family HMM PF04891.
  
 0.852
MCA0211
Conserved hypothetical protein; Identified by similarity to GP:12620472.
       0.775
