STRINGSTRING
obg protein (Sinorhizobium medicae) - STRING interaction network
"obg" - GTPase Obg in Sinorhizobium medicae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

obgGTPase Obg; 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 (336 aa)    
Predicted Functional Partners:
rplU
50S ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20 (124 aa)
 
  0.978
lepA
Elongation factor 4; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back- translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner (611 aa)
   
   
  0.939
proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate (393 aa)
   
   
  0.925
rpmA
PFAM- ribosomal protein L27; KEGG- ret-RHE_CH04063 50S ribosomal protein L27; Belongs to the bacterial ribosomal protein bL27 family (89 aa)
 
  0.910
rplM
50S ribosomal protein L13; 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 (154 aa)
 
 
  0.901
proA
Gamma-glutamyl phosphate reductase; Catalyzes the NADPH-dependent reduction of L-glutamate 5-phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5- carboxylate; Belongs to the gamma-glutamyl phosphate reductase family (427 aa)
         
  0.900
rplE
50S ribosomal protein L5; This is 1 of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance. In the 70S ribosome it contacts protein S13 of the 30S subunit (bridge B1b), connecting the 2 subunits; this bridge is implicated in subunit movement. Contacts the P site tRNA; the 5S rRNA and some of its associated proteins might help stabilize positioning of ribosome-bound tRNAs (185 aa)
   
 
  0.893
ruvB
Holliday junction ATP-dependent DNA helicase RuvB; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing (346 aa)
 
        0.890
nadD
Probable nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD) (202 aa)
 
          0.881
rplX
50S ribosomal protein L24; One of two assembly initiator proteins, it binds directly to the 5’-end of the 23S rRNA, where it nucleates assembly of the 50S subunit (103 aa)
