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

rpmH50S ribosomal subunit protein L34; Protein involved in structural constituent of ribosome and translation; Belongs to the bacterial ribosomal protein bL34 family. (46 aa)    
Predicted Functional Partners:
relA
(p)ppGpp synthetase I/GTP pyrophosphokinase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response which coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp. The second messengers ppGpp and c-di-GMP together control biofilm formation in response to translational stress; ppGpp represses biofilm formation while c-di-GMP induces it. ppGpp activates transcription of CsrA-antagonistic small RNAs CsrB and CsrC, which d [...]

rplM
50S ribosomal subunit 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.

tufA
Translation elongation factor EF-Tu 1; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis. Plays a stimulatory role in trans-translation; binds tmRNA. (Microbial infection) Upon infection by bacteriophage Qbeta, part of the viral RNA-dependent RNA polymerase complex. With EF-Ts may provide a stabilizing scaffold for the beta (catalytic) subunit. Helps separate the double-stranded RNA of the template and growing RNA during elongation. With the beta subunit helps form the exit tunnel for template RNA. (Microbial infe [...]

rpmB
50S ribosomal subunit protein L28; Protein involved in structural constituent of ribosome and translation.

rnpA
Protein C5 component of RNase P; RNaseP catalyzes the removal of the 5'-leader sequence from pre-tRNA to produce the mature 5'-terminus. It can also cleave other RNA substrates such as 4.5S RNA. The protein component plays an auxiliary but essential role in vivo by binding to the 5'-leader sequence and broadening the substrate specificity of the ribozyme.

rplK
50S ribosomal subunit protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors; Belongs to the universal ribosomal protein uL11 family.
   
 
 0.999
rplJ
50S ribosomal subunit protein L10; Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors. Belongs to the universal ribosomal protein uL10 family.

arfA
Alternate ribosome-rescue factor A; Rescues ribosomes stalled at the 3' end of non-stop mRNAs. This activity is crucial when the stalled ribosome cannot be rescued by the SsrA(tmRNA)-SmpB quality control system. Binds the 30S subunit, contacting 16S rRNA with the N-terminus near the decoding center and its C-terminus in the mRNA entry channel; contacts change in the presence of release factor 2 (RF2, also named PrfB). Requires RF2/PrfB to hydrolyze stalled peptidyl-tRNA on the ribosome; recruits and probably helps position RF2/PrfB correctly in the ribosomal A site so RF2's GGQ motif c [...]

rpsT
30S ribosomal subunit protein S20; Binds directly to 16S ribosomal RNA.
  
 
 0.998
rpsP
30S ribosomal subunit protein S16; In addition to being a ribosomal protein, S16 also has a cation-dependent endonuclease activity.
