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

Score
obgGTP1/OBG family protein; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family. (327 aa)    
Predicted Functional Partners:
rsfS
Iojap-related protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.
  
 
 0.903
rpmA
LSU ribosomal protein L27P; Alternative locus ID: P9312_15641; Belongs to the bacterial ribosomal protein bL27 family.
 
 
 0.902
rplT
LSU ribosomal protein L20P; Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit.
 
 
 0.898
rplU
LSU ribosomal protein L21P; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
 
 
 0.882
rplS
LSU ribosomal protein L19P; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
  
 
 0.868
rplK
LSU ribosomal protein L11P; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
  
 
 0.860
rplQ
LSU ribosomal protein L17P; Alternative locus ID: P9312_17771.
   
 
 0.836
rpmF
LSU ribosomal protein L32P; Alternative locus ID: P9312_10111; Belongs to the bacterial ribosomal protein bL32 family.
  
 
 0.833
rplI2
LSU ribosomal protein L9P; Binds to the 23S rRNA.
   
 
 0.811
rplB
LSU ribosomal protein L2P; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.
