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.

MCA0232Ferredoxin, 2Fe-2S; Identified by similarity to SP:P37097; match to protein family HMM PF00111. (122 aa)    
Predicted Functional Partners:
nifK
Nitrogenase molybdenum-iron protein beta chain; 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.
 
 
 0.946
nifD
Nitrogenase molybdenum-iron protein alpha chain; Identified by similarity to SP:P06120; match to protein family HMM PF00148; match to protein family HMM TIGR01282; match to protein family HMM TIGR01862.
 
 
 0.931
nifH
Nitrogenase 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; Belongs to the NifH/BchL/ChlL family.
  
 
 0.915
MCA0236
Conserved hypothetical protein; Identified by similarity to GP:12620458; match to protein family HMM PF03270.
 
  
 0.892
MCA0239
Putative nitrogen fixation protein nifQ; Identified by similarity to SP:P11068; match to protein family HMM PF04891.
 
 0.875
nuoCD
NADH dehydrogenase I, C/D subunits; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the N-terminal section; belongs to the complex I 30 kDa subunit family.
  
 
 0.841
MCA0238
Ferredoxin, 4Fe-4S; Identified by similarity to SP:P46036; match to protein family HMM PF00037.
 
 
 0.838
MCA2577
Putative dehydrogenase subunit; Identified by similarity to GP:4007678; match to protein family HMM PF01257; match to protein family HMM PF01512.
  
 
 0.813
MCA2724
NAD-reducing hydrogenase, alpha subunit; Identified by similarity to SP:P22317; match to protein family HMM PF01257; match to protein family HMM PF01512.
  
 
 0.813
MCA1697
Flavodoxin; Low-potential electron donor to a number of redox enzymes. Belongs to the flavodoxin family.
