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

cysHPhosophoadenylyl-sulfate reductase; Reduction of activated sulfate into sulfite. (240 aa)    
Predicted Functional Partners:
cysC
Adenylylsulfate kinase; Catalyzes the synthesis of activated sulfate.
 
 0.999
cysN
Putative nodQ bifunctional enzyme; 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.
 0.999
MCA2059
Nitrite/sulfite reductase protein; Identified by match to protein family HMM PF01077; match to protein family HMM PF03460.
 
 0.998
cysD
Sulfate adenylyltransferase, subunit 2; Identified by similarity to SP:O50273; match to protein family HMM PF01507; match to protein family HMM TIGR02039.
  
 0.996
MCA0431
Flavodoxin domain protein; 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.
  
 
 0.966
cysG
Siroheme 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.
 
  
 0.944
cysQ
3'(2'),5'-bisphosphate nucleotidase; Converts adenosine-3',5'-bisphosphate (PAP) to AMP. Belongs to the inositol monophosphatase superfamily. CysQ family.
  
 
 0.935
sseA
Mercaptopyruvate sulfurtransferase; Identified by similarity to GP:6009981; match to protein family HMM PF00581.
    
 0.920
MCA0225
Rieske 2Fe-2S family protein; Identified by similarity to GP:1754625; match to protein family HMM PF00355.
     
 0.902
MCA0586
Rieske 2Fe-2S family protein; Identified by similarity to GP:1754625; match to protein family HMM PF00355.
