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

cysISulfite reductase [NADPH] hemoprotein beta-component (SIR-HP); 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. (576 aa)    
Predicted Functional Partners:
cysJ
Sulfite reductase [NADPH] flavoprotein alpha-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. 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.
 0.999
cysH
Phosphoadenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite. Belongs to the PAPS reductase family. CysH subfamily.
 
 
 0.997
cysG
Sirohaem 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.
 
  
 0.964
sseA
Sulfurtransferase; Truncated gene. Similar to N-terminal region of transposase.
    
 0.935
cysK
Cysteine synthase A (O-acetylserine sulfhydrolase A); Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 
 0.932
plu3861
PALP domain-containing protein; Unnamed protein product; Similar to cysteine synthase.
  
 
 0.932
cysC
Adenylyl-sulfate kinase; Catalyzes the synthesis of activated sulfate.
 
  
 0.928
metB
Cystathionine gamma-synthase (CGS) (O-succinylhomoserine (Thiol)-lyase).
  
 0.924
cysN
Sulfate adenylyltransferase subunit 1; 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.
  
  
 0.918
glpE
Thiosulfate sulfurtransferase GlpE; Catalyzes, although with low efficiency, the sulfur transfer reaction from thiosulfate to cyanide.
    
 0.914
