STRING protein interaction network
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 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
protein homology

yaeQUncharacterized protein YaeQ; Putative enzyme; Not classified (181 aa)    
Predicted Functional Partners:
Transcription antitermination protein; Enhances distal genes transcription elongation in a specialized subset of operons that encode extracytoplasmic components. RfaH is recruited into a multi-component RNA polymerase complex by the ops element, which is a short conserved DNA sequence located downstream of the main promoter of these operons. Once bound, RfaH suppresses pausing and inhibits Rho-dependent and intrinsic termination at a subset of sites. Termination signals are bypassed, which allows complete synthesis of long RNA chains. Enhances expression of several operons involved in [...]
Putative dna-binding transcriptional regulator yfec; To E.coli YfiI and P.aeruginosa RluD
Rescues stalled ribosomes Can hydrolyze peptidyl-tRNA on ribosomes stalled by both non-stop mRNAs and mRNAs that contain rare codon clusters or ribosomes stalled in the middle of mRNA . First identified as a complementary ribosome rescue system when the stalled ribosome cannot be rescued by the SsrA(tmRNA)- SmpB quality control system or the alternative ribosome-rescue factor A (arfA)
Lipoprotein involved with copper homeostasis and adhesion; Involved in copper homeostasis, could be involved in both copper efflux and the delivery of copper to copper-dependent enzymes . Required for efficient binding of stationary phase cells to hydrophobic surfaces, part of the process of biofilm formation . Functions during envelope stress responses; when overproduced induces degP through the activation of the two-component envelope stress response system CpxA/CpxR DegP induction seems to require membrane anchoring of this protein . Structural changes and/or interaction of the CXXC [...]
Modulator of rho-dependent transcription termination; Suppresses temperature-sensitive mutations in essential genes by modulating rho-dependent transcription termination
UPF0253 family protein YaeP; Belongs to the UPF0253 family
Single-stranded-DNA-specific exonuclease. Required for many types of recombinational events, although the stringency of the requirement for RecJ appears to vary with the type of recombinational event monitored and the other recombination gene products which are available
Putative outer membrane fimbrial subunit export usher protein; Part of the elfADCG-ycbUVF fimbrial operon, which promotes adhesion of bacteria to different abiotic surfaces. Could be involved in the export and assembly of the ElfA fimbrial subunits across the outer membrane
Putative metal-dependent hydrolase; Specifically catalyzes the hydrolysis of UTP to UMP and diphosphate in vitro, albeit at apparently slow rate. Shows no activity towards ATP, GTP, CTP, dTTP and ITP as substrates
