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.

selDSelenophosphate synthase; Synthesizes selenophosphate from selenide and ATP. (347 aa)    
Predicted Functional Partners:
selA
Selenocysteine synthase; Converts seryl-tRNA(Sec) to selenocysteinyl-tRNA(Sec) required for selenoprotein biosynthesis; Belongs to the SelA family.
 
  
 0.999
ybbB
Putative ATPase; Involved in the post-transcriptional modification of the uridine at the wobble position (U34) of tRNA(Lys), tRNA(Glu) and tRNA(Gln). Catalyzes the conversion of 2-thiouridine (S2U-RNA) to 2-selenouridine (Se2U-RNA). Acts in a two-step process involving geranylation of 2-thiouridine (S2U) to S-geranyl-2-thiouridine (geS2U) and subsequent selenation of the latter derivative to 2-selenouridine (Se2U) in the tRNA chain (Probable); Belongs to the SelU family.

selB
Similar to E. coli selenocysteinyl-tRNA-specific translation factor (AAC76614.1); Blastp hit to AAC76614.1 (614 aa), 85% identity in aa 1 - 614.
 
   
 0.986
nifS
Putative aminotransferase class-V; 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 and selenium atoms from cysteine and selenocysteine 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. Also functions as a selenium delivery protein in the pathway for the biosynthesis of selenophosphate; Belongs to the class-V pyridoxal-phosphate-dependent [...]

STM4446
Putative selenocysteine synthase; [L-seryl-tRNA(Ser) selenium transferase].
 
  
 0.929
trxB
Similar to E. coli thioredoxin reductase (AAC73974.1); Blastp hit to AAC73974.1 (321 aa), 96% identity in aa 1 - 320.
   
 
 0.925
sufS
Selenocysteine lyase; Cysteine desulfurases mobilize the sulfur from L-cysteine to yield L-alanine, an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Component of the suf operon, which is activated and required under specific conditions such as oxidative stress and iron limitation. Acts as a potent selenocysteine lyase in vitro, that mobilizes selenium from L- selenocysteine. Selenocysteine lyase activity is however unsure in vivo.
 
 
 0.921
fdhD
Putative formate dehydrogenase formation protein; Required for formate dehydrogenase (FDH) activity. Acts as a sulfur carrier protein that transfers sulfur from IscS to the molybdenum cofactor prior to its insertion into FDH. Belongs to the FdhD family.
  
  
 0.890
STM3768
Putative selenocysteine synthase (L-seryl-tRNA(Ser) selenium transferase).
 
  
 0.883
fdhE
Putative formate dehydrogenase formation protein; Necessary for formate dehydrogenase activity. Belongs to the FdhE family.
