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

cysGUroporphyrinogen-III C-methyltransferase; 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. In the N-terminal section; belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family. (457 aa)    
Predicted Functional Partners:
hemC
Hydroxymethylbilane synthase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
  
 0.994
cysH
Phosphoadenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite.
 
  
 0.992
cysI
Sulfite reductase, beta subunit, NAD(P)-binding, heme-binding; Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
  
 0.991
hemD
Uroporphyrinogen III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III. Belongs to the uroporphyrinogen-III synthase family.
  
 
 0.973
cysC
Adenosine 5'-phosphosulfate kinase; Catalyzes the synthesis of activated sulfate.
  
  
 0.971
nirD
Nitrite reductase (NADH) small subunit; Required for activity of the reductase. To B.subtilis NasE.
 
  
 0.967
nirC
Nitrite transporter; Catalyzes nitrite uptake and nitrite export across the cytoplasmic membrane. Is up to 10-fold more active than NarK or NarU in nitrite uptake for subsequent reduction in the cytoplasm by the NirB/NirD nitrite reductase; Belongs to the FNT transporter (TC 2.A.44) family.
 
  
 0.967
cysD
ATP:sulfurylase (ATP:sulfate adenylyltransferase), subunit 2; Protein involved in sulfur metabolic process; Belongs to the PAPS reductase family. CysD subfamily.

 0.957
hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
    
 0.945
