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

gmkGuanylate kinase, putative; Essential for recycling GMP and indirectly, cGMP. (190 aa)    
Predicted Functional Partners:
guaA
GMP synthase, glutamine-hydrolyzing; Catalyzes the synthesis of GMP from XMP.
  
 
 0.960
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.956
pyk
Pyruvate kinase; Identified by match to protein family HMM PF00224; match to protein family HMM PF00391; match to protein family HMM PF02887; match to protein family HMM TIGR01064; Belongs to the pyruvate kinase family.
  
 
 0.948
rpoZ
Putative DNA-directed RNA polymerase, omega subunit; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
  
  
 0.941
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
   
 0.932
sync_2702
RelA/SpoT family protein; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance.
  
 
 0.929
sync_2880
Glutamine amidotransferase, class I; Identified by match to protein family HMM PF00117.
  
 
 0.916
surE
Acid phosphatase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
  0.900
sync_1158
Possible phosphoribosyltransferase family protein.
     
  0.900
sync_1265
Ribonucleotide reductase (Class II); Identified by match to protein family HMM TIGR02505.
     
  0.900
