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

cysGSiroheme 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. (457 aa)    
Predicted Functional Partners:
hemC
Porphobilinogen deaminase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
  
 0.996
cysI
Sulfite reductase [NADPH] hemoprotein beta-component; 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.
 
  
 0.982
hemD
Uroporphyrinogen-III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
 
 
 0.979
cysH
Phosphoadenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite.
 
  
 0.973
hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
    
 0.973
cysC
Adenylylsulfate kinase; Catalyzes the synthesis of activated sulfate.
  
  
 0.966
gltB
Glutamate synthase [NADPH] large chain precursor; Escherichia coli K-12 ortholog: b3212; Escherichia coli O157:H7 ortholog: z4576.
 
   
 0.955
nirD
Nitrite reductase [NAD(P)H] small subunit; Escherichia coli K-12 ortholog: b3366; Escherichia coli O157:H7 ortholog: z4727.
 
  
 0.950
cysD
Sulfate adenylyltransferase subunit 2; Escherichia coli K-12 ortholog: b2752; Escherichia coli O157:H7 ortholog: z4060.
 
  
 0.939
metH
5-methyltetrahydrofolate--homocysteine methyltransferase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
  
  
 0.923
