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

kguAPutative guanylate kinase; Essential for recycling GMP and indirectly, cGMP. (220 aa)    
Predicted Functional Partners:
RPA3070
Conserved unknown protein; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.
 
  
 0.983
guaA
GMP synthetase; Catalyzes the synthesis of GMP from XMP.
 
 
 0.973
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.970
pyk
Pyruvate kinase; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished; Belongs to the pyruvate kinase family.
 
 
 0.938
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.
  
 0.936
RPA3814
Calcium-binding EF-hand; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.
   
 0.936
guaC
GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides.
  
 
 0.929
relA
GTP pyrophosphokinase; 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.
  
 
 0.927
eno
Enolase; Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis; Belongs to the enolase family.
 
 
 0.926
RPA2271
Putative Pyruvate kinase; Belongs to the pyruvate kinase family.
  
 
 0.924
