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

Predicted Functional Partners:
XM1_1582
Putative exopolyphosphatase（Ppx/GppA phosphatase,29-324） Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
 
 
 0.942
XM1_3695
Exopolyphosphatase; Function of strongly homologous gene; enzyme.
 
 
 0.938
mazG
Nucleoside triphosphate pyrophosphohydrolase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 
 0.930
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.930
pyk
Pyruvate kinase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the pyruvate kinase family.

XM1_0739
Putative Ribonucleoside-diphosphate reductase; Catalyzes the reduction of ribonucleotides to deoxyribonucleotides. May function to provide a pool of deoxyribonucleotide precursors for DNA repair during oxygen limitation and/or for immediate growth after restoration of oxygen.
     
 0.904
nrd
Vitamin B12-dependent ribonucleotide reductase; Catalyzes the reduction of ribonucleotides to deoxyribonucleotides. May function to provide a pool of deoxyribonucleotide precursors for DNA repair during oxygen limitation and/or for immediate growth after restoration of oxygen.
     
 0.904
XM1_1846
Putative Adenylate cyclase 1(Adenylyl cyclase class-3/4/guanylyl cyclase,482-667); Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
     
 0.901
XM1_2198
