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.

hemDUroporphyrinogen III synthase HEM4. (281 aa)    
Predicted Functional Partners:
RPA1505
Putative porphobilinogen deaminase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
 
 0.988
cysG
Putative siroheme synthase; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme.
 
 
 0.972
hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
  
 
 0.951
hemB
Delta-aminolevulinic acid dehydratase; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished; Belongs to the ALAD family.
  
 
 0.951
cobA
Putative uroporphyrin III methylase; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.
 
 
 0.935
RPA0256
Putative UROPORPHYRINOGEN-III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
     
  0.900
hemZ
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
  
  
 0.833
hemF
Putative coproporphyrinogen III oxidase precursor; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.
     
 0.794
cycV,
Heme exporter protein A (heme ABC transporter ATP-binding protein), cytochrome c biogenesis; Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. CcmA exporter (TC 3.A.1.107) family.
     
 0.780
RPA0123
Possible KTN NAD-binding domain involved with K+ transport.
  
    0.628
