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
Your Input:
Gene Fusion
rraARibonuclease e (rnase e) inhibitor protein; Globally modulates RNA abundance by binding to RNase E (Rne) and regulating its endonucleolytic activity. Can modulate Rne action in a substrate-dependent manner by altering the composition of the degradosome. Modulates RNA-binding and helicase activities of the degradosome (161 aa)    
Predicted Functional Partners:
Regulator of ribonuclease activity b; Globally modulates RNA abundance by binding to RNase E (Rne) and regulating its endonucleolytic activity. Can modulate Rne action in a substrate-dependent manner by altering the composition of the degradosome
Atp-dependent rna helicase srmb; DEAD-box RNA helicase involved in the assembly of the 50S ribosomal subunit at low temperature. Exhibits RNA-stimulated ATP hydrolysis and RNA unwinding activity. Acts before DeaD
Atp-dependent rna helicase rhlb; DEAD-box RNA helicase involved in RNA degradation. Has RNA- dependent ATPase activity and unwinds double-stranded RNA
Essential cell division protein that activates septal peptidoglycan synthesis and constriction of the cell. Acts on both sides of the membrane, via interaction with FtsA in the cytoplasm and interaction with the FtsQBL complex in the periplasm. These interactions may induce a conformational switch in both FtsA and FtsQBL, leading to septal peptidoglycan synthesis by FtsI and associated synthases (Probable) . Required for full FtsI activity . Required for recruitment of AmiC to the septal ring
Endoribonuclease that plays a central role in RNA processing and decay. Required for the maturation of 5S and 16S rRNAs and the majority of tRNAs. Also involved in the degradation of most mRNAs. Can also process other RNA species, such as RNAI, a molecule that controls the replication of ColE1 plasmid, and the cell division inhibitor DicF- RNA. It initiates the decay of RNAs by cutting them internally near their 5'-end. It is able to remove poly(A) tails by an endonucleolytic process. Required to initiate rRNA degradation during both starvation and quality control; acts after RNase PH [...]
2'-O-acetyl-ADP-ribose deacetylase, regulator of RNase III activity; Deacetylates O-acetyl-ADP ribose to yield ADP-ribose and free acetate . Down-regulates ribonuclease 3 (RNase III) activity. Acts by interacting directly with the region of the ribonuclease that is required for dimerization/activation . Overexpression inhibits biofilm formation via an RNase III-independent pathway. This inhibition is RpoS-dependent . Overexpression also results in increased susceptibility to apramycin
Rna-binding protein hfq; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Involved in the regulation of stress responses mediated by the sigma factors RpoS, sigma-E and sigma-32 . Binds with high specificity to tRNAs . Binds sRNA antitoxin RalA . In vitro, stimulates synthesis of long tails by poly(A) polymerase I . Required for RNA phage Qbeta replication . Seems to play a role in persister cell formation; upon overexpression decreas [...]
1,4-dihydroxy-2-naphthoate polyprenyltransferase; Conversion of 1,4-dihydroxy-2-naphthoate (DHNA) to demethylmenaquinone (DMK). Attaches octaprenylpyrophosphate, a membrane-bound 40-carbon side chain to DHNA. The conversion of DHNA to DMK proceeds in three stages: the removal of the carboxyl group of DHNA as CO(2), the attachment of the isoprenoid side chain, and a quinol-to- quinone oxidation, which is thought to be spontaneous
annotation not available
Putative (di)nucleoside polyphosphate hydrolase; Master regulator of 5'-end-dependent mRNA decay . Accelerates the degradation of transcripts by removing pyrophosphate from the 5'-end of triphosphorylated RNA, leading to a more labile monophosphorylated state that can stimulate subsequent ribonuclease cleavage . Preferentially hydrolyzes diadenosine penta-phosphate with ATP as one of the reaction products . Also able to hydrolyze diadenosine hexa- and tetra-phosphate . Has no activity on diadenosine tri-phosphate, ADP-ribose, NADH and UDP-glucose . In an RNase PH (rph) wild-type strain [...]
