STRINGSTRING
lepA protein (Maritimibacter alkaliphilus) - STRING interaction network
"lepA" - Ribosomal back-translocase LepA in Maritimibacter alkaliphilus
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

lepARibosomal back-translocase LepA ; 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 (599 aa)    
Predicted Functional Partners:
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 (280 aa)
   
   
  0.902
leuS
Leucyl-tRNA synthetase (848 aa)
 
   
  0.900
recA
Recombinase A ; Can catalyze the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage (361 aa)
   
 
  0.894
prfA
Peptide chain release factor 1 ; Peptide chain release factor 1 directs the termination of translation in response to the peptide chain termination codons UAG and UAA (351 aa)
 
   
  0.880
RB2654_16196
Signal peptidase I (259 aa)
   
   
  0.863
obg
GTP-binding protein 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 (348 aa)
   
   
  0.860
ileS
Isoleucyl-tRNA synthetase ; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as ’pretransfer’ editing and involves the hydrolysis of activated Val-AMP. The other activity is designated ’posttransfer’ editing and involves deacylation of mischarged Val-tRNA(Ile) (996 aa)
   
   
  0.841
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)
 
 
  0.838
gidA
Glucose-inhibited division protein A ; NAD-binding protein involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA-cmnm(5)s(2)U34 (625 aa)
 
   
  0.831
pheS
Phenylalanyl-tRNA synthetase alpha subunit (357 aa)
   
   
  0.817
