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

hemGProtoporphyrin oxidase, flavoprotein; Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX using menaquinone as electron acceptor. (181 aa)    
Predicted Functional Partners:
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX; Belongs to the ferrochelatase family.
    
 0.991
hemF
Coproporphyrinogen III oxidase; Involved in the heme biosynthesis. Catalyzes the aerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen- IX.
     
 0.991
hemN
Coproporphyrinogen III oxidase, SAM and NAD(P)H dependent, oxygen-independent; Involved in the heme biosynthesis. Catalyzes the anaerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen III to yield the vinyl groups in protoporphyrinogen IX. It can use NAD or NADP, but NAD is preferred. Belongs to the anaerobic coproporphyrinogen-III oxidase family.
  
 
 0.963
hemY
Putative protoheme IX synthesis protein; Involved in a late step of protoheme IX synthesis.
   
  
 0.905
hemD
Uroporphyrinogen III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III. Belongs to the uroporphyrinogen-III synthase family.
  
  
 0.857
hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
  
  
 0.844
trkH
Potassium transporter; Low-affinity potassium transport system. Interacts with Trk system potassium uptake protein TrkA. Requires TrkE (sapD) for transport activity, 20% more uptake is seen with both SapD and SapF. Transport in the absence of SapD and SapF is dependent on a high membrane potential and a high cytoplasmic ATP concentration, suggesting this protein may be able to interact with other ATP-binding proteins. Can transport potassium and rubidium.
  
  
 0.792
hemB
5-aminolevulinate dehydratase (porphobilinogen synthase); Catalyzes an early step in the biosynthesis of tetrapyrroles. Binds two molecules of 5-aminolevulinate per subunit, each at a distinct site, and catalyzes their condensation to form porphobilinogen; Belongs to the ALAD family.
      
 0.784
hemL
Glutamate-1-semialdehyde aminotransferase (aminomutase).
      
 0.780
yigZ
UPF0029 family protein; Protein involved in translation; Belongs to the IMPACT family.
  
  
 0.771
