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

cysHPhosphoadenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite. Belongs to the PAPS reductase family. CysH subfamily. (246 aa)    
Predicted Functional Partners:
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.
 
 0.999
CysJ
Sulfite reductase, alpha subunit (flavoprotein); 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.
 
 
 0.998
cysC
Adenosine 5'-phosphosulfate kinase; Catalyzes the synthesis of activated sulfate.
 0.998
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.
 0.995
cysG
Multifunctional 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. Belongs to the precorrin methyltransferase family. In the N-terminal section; belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family.
 
  
 0.978
cysD
ATP-sulfurylase, subunit 2 (ATP:sulfate adenylyltransferase); COG0175 3'-phosphoadenosine 5'-phosphosulfate sulfotransferase (PAPS reductase)/FAD synthetase and related enzymes.
 
 
 0.969
cysQ
Carbohydrate phosphatase; Converts adenosine-3',5'-bisphosphate (PAP) to AMP. Belongs to the inositol monophosphatase superfamily. CysQ family.
  
 
 0.920
cysQ-2
Putative PAP (3',5' adenosine diphosphate) 3' phosphatase; Converts adenosine-3',5'-bisphosphate (PAP) to AMP. Belongs to the inositol monophosphatase superfamily. CysQ family.
  
 
 0.920
SseA
Putative 3-mercaptopyruvate sulfurtransferase; COG2897 Rhodanese-related sulfurtransferase.
    
 0.920
glpE
Thiosulfate sulfurtransferase; Catalyzes, although with low efficiency, the sulfur transfer reaction from thiosulfate to cyanide.
     
 0.905
