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; Essential for recycling GMP and indirectly, cGMP. (186 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 
 
 0.972
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.960
AFZ46496.1
PFAM: Pyruvate kinase, barrel domain; PEP-utilising enzyme, mobile domain; Pyruvate kinase, alpha/beta domain; TIGRFAM: pyruvate kinase; COGs: COG0469 Pyruvate kinase; InterPro IPR015793:IPR015794:IPR008279:IPR001697; KEGG: cyc:PCC7424_3440 pyruvate kinase; PFAM: Pyruvate kinase barrel; Pyruvate kinase alpha/beta; PEP-utilising protein mobile region; SPTR: Pyruvate kinase; TIGRFAM: pyruvate kinase; Belongs to the pyruvate kinase family.

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.
   
 0.927
rpoZ
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.
  
  
 0.921
AFZ47487.1
Ribonucleoside-diphosphate reductase, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
     
 0.918
AFZ46324.1
(p)ppGpp synthetase I, SpoT/RelA; 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.
  
 
 0.915
AFZ47829.1
Ribonucleotide reductase; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides; Belongs to the ribonucleoside diphosphate reductase small chain family.
     
 0.908
AFZ46593.1
5'-nucleotidase; PFAM: Survival protein SurE; TIGRFAM: 5'/3'-nucleotidase SurE; COGs: COG0496 acid phosphatase; InterPro IPR002828; KEGG: cyh:Cyan8802_2176 stationary-phase survival protein SurE; PFAM: Survival protein SurE; SPTR: Stationary-phase survival protein SurE; TIGRFAM: stationary-phase survival protein SurE; exopolyphosphatase.
     
  0.900
surE
5'-nucleotidase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
  0.900
