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

cysISulfite reductase (NADPH) beta 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. (562 aa)    
Predicted Functional Partners:
Ping_3434
Sulfite reductase (NADPH) 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. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component.

cysH
Phosphoadenylylsulfate reductase (thioredoxin); Reduction of activated sulfate into sulfite. Belongs to the PAPS reductase family. CysH subfamily.
 
 0.999
Ping_0272
PFAM: oxidoreductase FAD/NAD(P)-binding domain protein; PepSY-associated TM helix domain protein; flavodoxin/nitric oxide synthase; KEGG: eba:ebA3193 putative oxidoreductase, FAD-binding.
 
 0.988
Ping_2438
TIGRFAM: cysteine synthases; cysteine synthase A; PFAM: Pyridoxal-5'-phosphate-dependent enzyme, beta subunit; KEGG: sdn:Sden_2520 cysteine synthase A; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 
 0.966
cysG
uroporphyrinogen-III C-methyltransferase / precorrin-2 dehydrogenase; 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.
