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

C882_3818GTP 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. (725 aa)    
Predicted Functional Partners:
rpsF
SSU ribosomal protein S6p; Binds together with S18 to 16S ribosomal RNA.
  
 
 0.980
rpsM
SSU ribosomal protein S13p (S18e); Located at the top of the head of the 30S subunit, it contacts several helices of the 16S rRNA. In the 70S ribosome it contacts the 23S rRNA (bridge B1a) and protein L5 of the 50S subunit (bridge B1b), connecting the 2 subunits; these bridges are implicated in subunit movement. Contacts the tRNAs in the A and P-sites. Belongs to the universal ribosomal protein uS13 family.
    
  0.978
rplK
LSU ribosomal protein L11p (L12e); Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
  
 
 0.976
rplC
LSU ribosomal protein L3p (L3e); One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.
    
  0.974
rpsI
SSU ribosomal protein S9p (S16e); Belongs to the universal ribosomal protein uS9 family.
   
 
 0.973
rpsE
SSU ribosomal protein S5p (S2e); Located at the back of the 30S subunit body where it stabilizes the conformation of the head with respect to the body. Belongs to the universal ribosomal protein uS5 family.
   
 
 0.972
rplM
LSU ribosomal protein L13p (L13Ae); 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.
   
 
 0.972
rpsL
SSU ribosomal protein S12p (S23e); Interacts with and stabilizes bases of the 16S rRNA that are involved in tRNA selection in the A site and with the mRNA backbone. Located at the interface of the 30S and 50S subunits, it traverses the body of the 30S subunit contacting proteins on the other side and probably holding the rRNA structure together. The combined cluster of proteins S8, S12 and S17 appears to hold together the shoulder and platform of the 30S subunit.
   
 
 0.972
C882_0601
LSU ribosomal protein L6p (L9e); 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.
    
 
 0.971
rplX
LSU ribosomal protein L24p (L26e); One of the proteins that surrounds the polypeptide exit tunnel on the outside of the subunit.
  
   0.971
