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

yqeHPutative LuxR family transcriptional regulator; To E.coli YkgK. (210 aa)    
Predicted Functional Partners:
obgE
GTPase involved in cell partioning and DNA repair; An abundant, essential GTPase which binds GTP, GDP and ppGpp with moderate affinity. Has high guanosine nucleotide exchange rate constants for GTP and GDP, and a relatively low GTP hydrolysis rate stimulated by the 50S ribosomal subunit. It is estimated there are 34000 molecules in log-phase cells and 5600 molecules in stationary- phase cells. Required for chromosome segregation. Plays a role in the stringent response, perhaps by sequestering 50S ribosomal subunits and decreasing protein synthesis , and a non-essential role in the late [...]

der
GTPase; GTPase that plays an essential role in the late steps of ribosome biogenesis. GTPase point mutations (but not a deletion mutant) are suppressed by mild overexpression of RelA, probably due to increased levels of the stringent response mediator (p)ppGpp. 50S subunits assembled in the absence of Der are defective and unable to assemble into 70S ribosomes. GTPase activity is stimulated by YihI. Overexpression rescues an rrmJ deletion, stabilizing the 70S ribosome. Der and RrmJ are likely to share a mechanism to stabilize 50S ribosomal subunits at a very late stage of 50S subunit m [...]

rsgA
Ribosome small subunit-dependent GTPase A; One of at least 4 proteins (Era, RbfA, RimM and RsgA/YjeQ) that assist in the late maturation steps of the functional core of the 30S ribosomal subunit. Binds the 30S subunit contacting the head, platform, and rRNA helix 44, which may assist the last maturation stages. Removes RbfA from mature, but not immature 30S ribosomes in a GTP- dependent manner; 95% removal in the presence of GTP, 90% removal in GMP-PNP and 65% removal in the presence of GDP. Circulary permuted GTPase that catalyzes rapid hydrolysis of GTP with a slow catalytic turnover [...]

yphC
Putative oxidoreductase.
      
 0.645
ychF
Catalase inhibitor protein; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner. Does not hydrolyze GTP; Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family. YchF/OLA1 subfamily.
      
 0.600
hflX
GTPase, stimulated by 50S subunit binding; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis. In vitro, also exhibits ATPase activity.
      
 0.522
yqeI
Putative transcriptional regulator; Putative sensory transducer; To V.cholerae cholera toxin transcriptional activator (ToxR).
  
  
 0.460
mnmE
tRNA U34 5-methylaminomethyl-2-thiouridine modification GTPase; Exhibits a very high intrinsic GTPase hydrolysis rate. Involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA- cmnm(5)s(2)U34.
