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.

Score
nifUNitrogen fixation protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins. (279 aa)    
Predicted Functional Partners:
nifS
Cysteine desulfurase; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine.
 
 0.994
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.
 
 0.983
hscB
Chaperone protein; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family.
 
 0.961
nifZ
Nitrogen fixation protein; Similar to Klebsiella pneumoniae NifZ protein NifZ SWALL:NIFZ_KLEPN (SWALL:P08533) (148 aa) fasta scores: E(): 3.6e-33, 57.24% id in 145 aa, and to Pantoea agglomerans NifZ protein NifZ SWALL:Q52072 (EMBL:X99694) (147 aa) fasta scores: E(): 5.6e-30, 56.55% id in 145 aa.
 
  
 0.935
hscA
Chaperone protein; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB. Involved in the maturation of IscU.
 
 0.895
iscR
Putative transcriptional regulator; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins.
  
  
 0.891
nifV
Homocitrate synthase; Similar to Klebsiella pneumoniae homocitrate synthase NifV SWALL:NIFV_KLEPN (SWALL:P05345) (381 aa) fasta scores: E(): 1.8e-100, 68.94% id in 380 aa, and to Enterobacter agglomerans homocitrate synthase NifV SWALL:NIFV_ENTAG (SWALL:Q52070) (400 aa) fasta scores: E(): 1.6e-95, 68.4% id in 364 aa; Belongs to the alpha-IPM synthase/homocitrate synthase family.
 
  
 0.887
fdx
Ferredoxin, 2Fe-2S; Similar to Escherichia coli, Escherichia coli O157:H7, and Shigella flexneri ferredoxin, 2fe-2s Fdx or b2525 or z3792 or ecs3391 or sf2572 SWALL:AAN44071 (EMBL:M88654) (111 aa) fasta scores: E(): 6.7e-39, 84.68% id in 111 aa.
 
 0.864
nfuA
Conserved hypothetical protein; Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S cluster, can transfer this cluster to apoproteins, and thereby intervenes in the maturation of Fe/S proteins. Could also act as a scaffold/chaperone for damaged Fe/S proteins.
  
 0.837
csdA
Similar to Escherichia coli cysteine sulfinate desulfinase CsdA or b2810 SWALL:CSDA_ECOLI (SWALL:Q46925) (401 aa) fasta scores: E(): 1.6e-104, 69.82% id in 401 aa, and to Salmonella typhimurium putative selenocysteine lyase csda or stm2984 SWALL:Q8ZMC3 (EMBL:AE008836) (401 aa) fasta scores: E(): 3.2e-101, 67.83% id in 401 aa.
