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

ML1465GTP1/Obg-family GTP-binding 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. (479 aa)    
Predicted Functional Partners:
rpmA
Highly similar to many 50s ribosomal proteins (L27) including: Escherichia coli SW:RL27_ECOLI (P02427) (84 aa); Fasta score E(): 5.8e-16, 63.9% identity in 83 aa overlap and Mycobacterium tuberculosis RV2441C SW:RL27_MYCTU (Z8145) (86 aa); Fasta score E(): 3.3e-28, 93.8% identity in 81 aa overlap. Contains Pfam match to entry PF01016 Ribosomal_L27, Ribosomal L27 protein. Contains PS00831 Ribosomal protein L27 signature; Belongs to the bacterial ribosomal protein bL27 family.

proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
  
  
 0.943
rplU
50S ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
 
 
 0.927
rplT
50S ribosomal protein L20; 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 (By similarity).
 
 
 0.890
ML1453
Conserved hypothetical 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.
  
 
 0.833
rplB
50S ribosomal protein L2; 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.
    
 
 0.786
rplS
50S ribosomal protein L19; 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.
  
 
 0.774
ML0997
Possible ATP/GTP-binding protein; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. HflX GTPase family.
  
  
 0.767
rplK
50S ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
  
 
 0.765
rplQ
Similar to M. tuberculosis 50S ribosomal protein L17 rplQ Rv3456c SW:RL17_MYCTU (O06323) (180 aa); Fasta score E(): 0, 81.9% identity in 171 aa overlap. Contains Pfam match to entry PF01196 Ribosomal_L17, Ribosomal protein L17.
