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.

HMBSPorphobilinogen deaminase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps; Belongs to the HMBS family. (361 aa)    
Predicted Functional Partners:
UROS
Uroporphyrinogen-III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III, the branch point for the various sub-pathways leading to the wide diversity of porphyrins. Porphyrins act as cofactors for a multitude of enzymes that perform a variety of processes within the cell such as methionine synthesis (vitamin B12) or oxygen transport (heme).
  
 0.999
ALAD
Delta-aminolevulinic acid dehydratase; 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.
 
 0.999
UROD
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
 0.996
FECH
Ferrochelatase, mitochondrial; Catalyzes the ferrous insertion into protoporphyrin IX; Belongs to the ferrochelatase family.
  
  
 0.975
PPOX
Protoporphyrinogen oxidase; Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX.
  
  
 0.970
CPOX
Oxygen-dependent coproporphyrinogen-III oxidase, mitochondrial; 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.
  
 
 0.956
ALAS1
5-aminolevulinate synthase, nonspecific, mitochondrial; 5'-aminolevulinate synthase 1; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
  
  
 0.917
ALAS2
5-aminolevulinate synthase, erythroid-specific, mitochondrial; 5'-aminolevulinate synthase 2.
  
  
 0.849
GABRE
Gamma-aminobutyric acid receptor subunit epsilon; GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel.
    
   0.829
NFU1
NFU1 iron-sulfur cluster scaffold homolog, mitochondrial; Iron-sulfur cluster scaffold protein which can assemble [4Fe- 4S] clusters and deliver them to target proteins. Belongs to the NifU family.
