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

nupCNucleoside (except guanosine) transporter; Transports nucleosides with a high affinity except guanosine and deoxyguanosine. Driven by a proton motive force. Transports cytidine, uridine, thymidine, adenosine and inosine. Can also transport xanthosine, but with a very low affinity (400 aa)    
Predicted Functional Partners:
nupG
Mfs transporter, nhs family, nucleoside permease; Broad-specificity transporter of purine and pyrimidine nucleosides. Driven by a proton motive force. Can transport uridine, adenosine, inosine, guanosine, thymidine and cytidine. Can also transport xanthosine, but with a very low affinity
      
 0.938
xapB
Mfs transporter, nhs family, xanthosine permease; Uptake of xanthosine. Driven by a proton motive force. Can also transport other nucleosides such as inosine, adenosine, cytidine, uridine and thymidine
      
 0.731
tsx
Nucleoside channel, receptor of phage t6 and colicin k; Functions as substrate-specific channel for nucleosides and deoxynucleosides . Has a greater affinity for deoxynucleosides than for nucleosides, and does not transport free bases . In addition, constitutes the receptor for colicin K and phage T6

ypfH
Palmitoyl-coa esterase activity, uncertain physiological substrate; Displays esterase activity toward palmitoyl-CoA and pNP- butyrate
      
 0.640
yhcF
DUF1120 domain-containing protein YhcF; To E.coli GltF

deoC
2-deoxyribose-5-phosphate aldolase, NAD(P)-linked; Catalyzes a reversible aldol reaction between acetaldehyde and D-glyceraldehyde 3-phosphate to generate 2-deoxy-D-ribose 5- phosphate . Can also catalyze the double aldol condensation of three acetaldehyde molecules, leading to the formation of 2,4,6-trideoxyhexose
     
 0.561
cytR
Laci family transcriptional regulator, repressor for deo operon, udp, cdd, tsx, nupc, and nupg; This protein negatively controls the transcription initiation of genes such as deoCABD, udp, and cdd encoding catabolizing enzymes and nupC, nupG, and tsx encoding transporting and pore-forming proteins. Binds cytidine and adenosine as effectors
      
 0.519
frwA
Putative pts enzyme: hpr, enzyme i and ii components; Multifunctional protein that includes general (non sugar- specific) and sugar-specific components of the phosphoenolpyruvate- dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II FrwABC PTS system is involved in fructose transport
