STRINGSTRING
obg protein (Arcobacter butzleri RM4018) - STRING interaction network
"obg" - GTPase Obg in Arcobacter butzleri RM4018
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 (363 aa)    
Predicted Functional Partners:
fmt
Methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl-tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus (306 aa)
 
   
  0.937
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 (595 aa)
   
   
  0.928
proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate (254 aa)
   
   
  0.906
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 (345 aa)
 
        0.902
rpmA
Pfam match to PF01016 Ribosomal_L27, score 189.8, E-value 5.8E-054; Belongs to the bacterial ribosomal protein bL27 family (85 aa)
 
  0.875
rplU
50S ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20 (105 aa)
   
 
  0.844
purE
N5-carboxyaminoimidazole ribonucleotide mutase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR) (164 aa)
 
        0.821
gcp
tRNA N6-adenosine threonylcarbamoyltransferase; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaE and TsaB. TsaD likely plays a direct catalytic role in this reaction; Belongs to the KAE1 / TsaD family (333 aa)
 
 
  0.814
infB
Translation initiation factor IF-2; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex (890 aa)
 
 
  0.806
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5’-3’ exonuclease activity (896 aa)
 
 
  0.802
