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

AEX84548.1(p)ppGpp synthetase, RelA/SpoT family; 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. (717 aa)    
Predicted Functional Partners:
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.929
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.
    
 0.921
rplK
50S ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
  
 
 0.918
AEX84602.1
PFAM: Pyruvate kinase, barrel domain; Pyruvate kinase, alpha/beta domain; TIGRFAM: pyruvate kinase; Belongs to the pyruvate kinase family.
   
 
 0.914
rplF
Ribosomal protein L6, bacterial type; This protein binds to the 23S rRNA, and is important in its secondary structure. It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center; Belongs to the universal ribosomal protein uL6 family.
    
 
 0.913
rpsO
Ribosomal protein S15; Forms an intersubunit bridge (bridge B4) with the 23S rRNA of the 50S subunit in the ribosome.
   
   0.911
rpsZ
Ribosomal protein S14; Binds 16S rRNA, required for the assembly of 30S particles and may also be responsible for determining the conformation of the 16S rRNA at the A site.
    
 
 0.908
rplM
Ribosomal protein L13, bacterial type; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
   
 
 0.907
rpsI
PFAM: Ribosomal protein S9/S16; Belongs to the universal ribosomal protein uS9 family.
   
 
 0.907
rplO
Ribosomal protein L15, bacterial/organelle; Binds to the 23S rRNA; Belongs to the universal ribosomal protein uL15 family.
   
   0.906
