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

nrfGHeme lyase (NrfEFG) for insertion of heme into c552, subunit NrfG; Required for formate-dependent nitrite reduction. Not required for the biosynthesis of any of the c-type cytochromes nor for the secretion of the periplasmic cytochromes. (198 aa)    
Predicted Functional Partners:
nrfF
Heme lyase (NrfEFG) for insertion of heme into c552, subunit NrfF; Not required for the biosynthesis of any of the c-type cytochromes. Possible subunit of a heme lyase.
  
 0.999
nrfE
Heme lyase (NrfEFG) for insertion of heme into c552, subunit NrfE; May be required for the biogenesis of c-type cytochromes. Possible subunit of a heme lyase.
 
  
 0.992
nrfB
Nitrite reductase, formate-dependent, penta-heme cytochrome c; Plays a role in nitrite reduction.
 
  
 0.979
nrfA
Nitrite reductase, formate-dependent, cytochrome; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process. Has very low activity toward hydroxylamine. Has even lower activity toward sulfite. Sulfite reductase activity is maximal at neutral pH (By similarity).
 
  
 0.973
nrfD
Formate-dependent nitrite reductase, membrane subunit; Probably involved in the transfer of electrons from the quinone pool to the type-c cytochromes; Belongs to the NrfD family.
 
  
 0.962
ccmF
Heme lyase, CcmF subunit; Required for the biogenesis of c-type cytochromes. Possible subunit of a heme lyase.
 
  
 0.916
nrfC
Formate-dependent nitrite reductase, 4Fe4S subunit; Probably involved in the transfer of electrons from the quinone pool to the type-c cytochromes.
 
  
 0.912
dsbE
Periplasmic thioredoxin of cytochrome c-type biogenesis; Involved in disulfide bond formation. Catalyzes a late, reductive step in the assembly of periplasmic c-type cytochromes, probably the reduction of disulfide bonds of the apocytochrome c to allow covalent linkage with the heme. Possible subunit of a heme lyase. DsbE is maintained in a reduced state by DsbD.
 
  
 0.858
ccmE
Periplasmic heme chaperone; Heme chaperone required for the biogenesis of c-type cytochromes. Transiently binds heme delivered by CcmC and transfers the heme to apo-cytochromes in a process facilitated by CcmF and CcmH; Belongs to the CcmE/CycJ family.
 
  
 0.789
ccmH
Heme lyase, CcmH subunit; May be required for the biogenesis of c-type cytochromes. Possible subunit of a heme lyase.
  
   
 0.786
