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

alr4551ORF_ID:alr4551; hypothetical protein. (145 aa)    
Predicted Functional Partners:
nifU
Nitrogen fixation protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
  
  
 0.860
alr2505
Cysteine desulfurase IscS; ORF_ID:alr2505; putative aminotransferase; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family.
 
  
 0.724
nifS
Nitrogenase cofactor synthesis protein; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Seems to participate in the biosynthesis of the nitrogenase metalloclusters by providing the inorganic sulfur required for the Fe-S core formation; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
 
  
 0.719
nifS-2
class-V aminotransferase; ORF_ID:alr3088; nifS gene product.
 
  
 0.717
alr4552
Cysteine synthase; ORF_ID:alr4552; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
  
 0.578
alr4553
ORF_ID:alr4553; similar to heat shock protein DnaJ.
       0.508
alr0821
ORF_ID:alr0821; hypothetical protein.
  
  
 0.468
alr4550
ORF_ID:alr4550; hypothetical protein; Belongs to the OprB family.
       0.457
alr2679
Polyketide synthase; ORF_ID:alr2679.
