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. In the N-terminal section; belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family. (457 aa)    
Predicted Functional Partners:
cysI
NADPH dependent sulfite reductase, alpha subunit; 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.
 
  
 0.996
hemC
Porphobilinogen deaminase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
  
 0.996
cysH
3'-phosphoadenosine 5'-phosphosulfate reductase; Reduction of activated sulfate into sulfite; Belongs to the PAPS reductase family. CysH subfamily.
 
  
 0.992
cbiK
Synthesis of vitamin B12 adenosyl cobalamide precursor; Catalyzes the insertion of Co(2+) into sirohydrochlorin as part of the anaerobic pathway to cobalamin biosynthesis; Belongs to the CbiK family.
 
 
 0.988
cysD
ATP-sulfurylase, subunit 1; Similar to E. coli ATP:sulfurylase (ATP:sulfate adenylyltransferase), subunit 2 (AAC75794.1); Blastp hit to AAC75794.1 (302 aa), 97% identity in aa 1 - 302.

cysJ
Sulfite reductase, beta (flavoprotein) subunit; 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. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component; Belongs to the NADPH-dependent sulphite reductase flavoprotein subunit CysJ family. In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.
  
 0.966
hemD
Uroporphyrinogen III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III. Belongs to the uroporphyrinogen-III synthase family.
  
 
 0.960
cbiL
