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

Gene Fusion
sraStationary-phase-induced ribosome-associated protein; Although this protein associates with the 30S subunit of the ribosome it is not considered to be a bona fide ribosomal protein (45 aa)    
Predicted Functional Partners:
HTH_CROC1 family putative transcriptional regulator; Uncharacterized HTH-type transcriptional regulator YiaG; Protein involved in regulation of transcription, DNA-dependent
Small subunit ribosomal protein s16; In addition to being a ribosomal protein, S16 also has a cation-dependent endonuclease activity
Small subunit ribosomal protein s9; The C-terminal tail plays a role in the affinity of the 30S P site for different tRNAs. Mutations that decrease this affinity are suppressed in the 70S ribosome
Ribosome-associated atpase: atp-binding protein/atp-binding membrane protein; Exhibits an intrinsic ATPase activity that is stimulated by both 70S ribosomes and 30S ribosomal subunits. Could be involved in protein-chain elongation and in release of deacyl-tRNA from ribosomes after peptide bond synthesis. Stimulates the synthesis of polyphenylalanine in vitro
Ribosome biogenesis gtpase / thiamine phosphate phosphatase; 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 c [...]
Small subunit ribosomal protein s18; Binds as a heterodimer with protein S6 to the central domain of the 16S rRNA, where it helps stabilize the platform of the 30S subunit
Ribosome modulation factor; During stationary phase, converts 70S ribosomes to an immature dimeric form (90S ribosomes) which are converted to inactive 100S ribosomes (a process called ribosomal hibernation) by the hibernation promoting factor HPF . Inactivates ribosomes by covering the peptidyl transferase (PTase) center of the 23S rRNA and the entrance of peptide exit tunnel . However crystallization with T.thermophilus 70S ribosomes shows it binds near the 3'-end of the 16S rRNA near the anti-Shine-Dalgarno sequence, where it would sterically hinder translation inititation . In this [...]
Lipoyl-dependent cys-based peroxidase, hydroperoxide resistance; Preferentially metabolizes organic hydroperoxides over inorganic hydrogen peroxide
Stationary phase translation inhibitor and ribosome stability factor; During stationary phase prevents 70S dimer formation, probably in order to regulate translation efficiency during transition between the exponential and the stationary phases . During environmental stress such as cold shock or excessive cell density at stationary phase, stabilizes the 70S ribosome against dissociation, inhibits translation elongation and increases translation accuracy . When normal growth conditions are restored, is quickly released from the ribosome . Has been suggested to inhibit translation elonga [...]
Stationary phase nucleoid protein that sequesters iron and protects dna from damage; During stationary phase, binds the chromosome non- specifically, forming a highly ordered and stable dps-DNA co-crystal within which chromosomal DNA is condensed and protected from diverse damages. It protects DNA from oxidative damage by sequestering intracellular Fe(2+) ion and storing it in the form of Fe(3+) oxyhydroxide mineral, which can be released after reduction. One hydrogen peroxide oxidizes two Fe(2+) ions, which prevents hydroxyl radical production by the Fenton reaction. Dps also protects [...]
