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

cysGMultifunctional siroheme synthase: uroporphyrinogen 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. (473 aa)    
Predicted Functional Partners:
hemC
Hydroxymethylbilane synthase (porphobilinogen deaminase); Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
  
 0.994
cysI
Sulfite reductase, beta subunit, NADPH-dependent hemoprotein; 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.
 
  
 0.989
cysC
Adenosine 5'-phosphosulfate kinase; Catalyzes the synthesis of activated sulfate.
  
  
 0.989
cysD
ATP-sulfurylase, subunit 2 (ATP:sulfate adenylyltransferase); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
  
 0.983
hemDX
uroporphyrinogen-III synthase HemD (N terminal)/Uroporphyrin-III C-methyltransferase (C terminal); Function of strongly homologous gene; enzyme.
 
 
 0.970
cysH
3'-phosphoadenosine 5'-phosphosulfate (PAPS) reductase; Reduction of activated sulfate into sulfite. Belongs to the PAPS reductase family. CysH subfamily.
 
  
 0.966
hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
    
 0.952
hemB
5-aminolevulinate dehydratase (porphobilinogen synthase); Function of strongly homologous gene; enzyme; Belongs to the ALAD family.
 
  
 0.923
cysN
ATP-sulfurylase, subunit 1 (ATP:sulfate adenylyltransferase); May be the GTPase, regulating ATP sulfurylase activity. Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. CysN/NodQ subfamily.
 
  
 0.907
PSHAb0097
Putative enzyme protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homolgy; enzyme.
  
  
 0.905
