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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

xanPXanthine permease XanP; Specific, proton motive force-dependent high-affinity transporter for xanthine; Belongs to the xanthine/uracil permease family. Nucleobase:cation symporter-2 (NCS2) (TC 2.A.40) subfamily (463 aa)    
Predicted Functional Partners:
yicH
annotation not available
      0.836
yeeE
UPF0394 inner membrane protein YeeE; Putative transport system permease protein
      
 0.754
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis
  
  
 0.720
codB
Cytosine permease; Required for cytosine transport into the cell
  
  
 0.707
purL
Phosphoribosylformylglycinamidine synthase; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate
  
  
 0.682
tsx
Nucleoside-specific channel-forming protein Tsx; 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
     
 0.627
adeP
Adenine permease AdeP; High-affinity transporter for adenine; Belongs to the xanthine/uracil permease family. AzgA purine transporter (TC 2.A.1.40) subfamily
 
  
 0.627
purN
Phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate; Belongs to the GART family
  
  
 0.617
glnB
Nitrogen regulatory protein P-II 1; P-II indirectly controls the transcription of the glutamine synthetase gene (glnA). P-II prevents NR-II-catalyzed conversion of NR-I to NR-I-phosphate, the transcriptional activator of GlnA. When P-II is uridylylated to P-II-UMP, these events are reversed. When the ratio of Gln to 2-ketoglutarate decreases, P-II is uridylylated to P-II-UMP, which causes the deadenylation of glutamine synthetase by GlnE, so activating the enzyme; Belongs to the P(II) protein family
      
 0.608
plaP
Low-affinity putrescine importer PlaP; Putrescine importer. Required for induction of type 1 pili-driven surface motility
   
  
 0.596
