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:
some 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

sbpSulfate/thiosulfate abc transporter periplasmic binding protein sbp; This protein specifically binds sulfate and is involved in its transmembrane transport (329 aa)    
Predicted Functional Partners:
cysW
Sulfate/thiosulfate abc transporter inner membrane subunit cysw; Part of the ABC transporter complex CysAWTP (TC 3.A.1.6.1) involved in sulfate/thiosulfate import. Probably responsible for the translocation of the substrate across the membrane
 
 0.999
cysU
Sulfate/thiosulfate abc transporter inner membrane subunit cysu; Part of the ABC transporter complex CysAWTP (TC 3.A.1.6.1) involved in sulfate/thiosulfate import. Probably responsible for the translocation of the substrate across the membrane
 
 0.998
cysA
Sulfate/thiosulfate transport system atp-binding protein; Part of the ABC transporter complex CysAWTP involved in sulfate/thiosulfate import. Responsible for energy coupling to the transport system
 
 0.997
cysN
Sulfate adenylyltransferase subunit 1; May be the GTPase, regulating ATP sulfurylase activity
 
 0.988
cysD
Sulfate adenylyltransferase subunit 2; Belongs to the PAPS reductase family. CysD subfamily
 
 
 0.966
cysI
Sulfite reductase, beta subunit, nad(p)-binding, heme-binding; 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
  
  
 0.956
cysP
Thiosulfate/sulfate abc transporter periplasmic binding protein cysp; Part of the ABC transporter complex CysAWTP (TC 3.A.1.6.1) involved in sulfate/thiosulfate import. This protein specifically binds thiosulfate and is involved in its transmembrane transport
 
0.930
cysH
Phosphoadenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite
 
  
 0.895
cysC
Adenosine 5'-phosphosulfate kinase; Catalyzes the synthesis of activated sulfate
  
  
 0.874
cysG
Uroporphyrin-iii c-methyltransferase / precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase; 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
