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

nifHNitrogenase iron protein; The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein and the molybdenum-iron protein. (274 aa)    
Predicted Functional Partners:
nifD
Nitrogenase molybdenum-iron protein, alpha subunit; Identified by similarity to EGAD:24701; match to protein family HMM PF00148; match to protein family HMM TIGR01282; match to protein family HMM TIGR01862.
 
 0.998
nifK
Nitrogenase molybdenum-iron protein, beta subunit; This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation; Belongs to the NifD/NifK/NifE/NifN family.
 
 0.998
nifB
nifB protein; Involved in the biosynthesis of the iron-molybdenum cofactor (FeMo-co or M-cluster) found in the dinitrogenase enzyme of the nitrogenase complex in nitrogen-fixing microorganisms. NifB catalyzes the crucial step of radical SAM-dependent carbide insertion that occurs concomitant with the insertion of a 9th sulfur and the rearrangement/coupling of two [4Fe-4S] clusters into a [8Fe-9S-C] cluster, the precursor to the M-cluster.
 
  
 0.986
nifE
Nitrogenase iron-molybdenum cofactor biosynthesis protein NifE; Identified by similarity to EGAD:6880; match to protein family HMM PF00148; match to protein family HMM TIGR01283; Belongs to the NifD/NifK/NifE/NifN family.
 
 
 0.973
nifN
Nitrogenase iron-molybdenum cofactor biosynthesis protein NifN, putative; Identified by similarity to EGAD:17496; match to protein family HMM PF00148; Belongs to the NifD/NifK/NifE/NifN family.
 
 
 0.963
hcp
Prismane family protein; Catalyzes the reduction of hydroxylamine to form NH(3) and H(2)O.
     
 0.913
gdhA
Glutamate dehydrogenase; Identified by similarity to EGAD:22862; match to protein family HMM PF00208; match to protein family HMM PF02812; Belongs to the Glu/Leu/Phe/Val dehydrogenases family.
     
 0.904
glnA
Glutamine synthetase; Identified by similarity to EGAD:21008; match to protein family HMM PF00120; Belongs to the glutamine synthetase family.
     
 0.901
bchB
Protochlorophyllide reductase, ChlB subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (BchN-BchB) is the catalytic component of the complex.
 
 
 0.858
bchN
Protochlorophyllide reductase, ChlN subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (BchN-BchB) is the catalytic component of the complex.
