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

rzpDDLP12 prophage; Necessary for host cell lysis. It is believed to code for an endopeptidase that cleaves the amino-carboxyl cross-link between the diaminopimelic acid and D-alanine residues in the murein component of the bacterial cell wall (By similarity). (153 aa)    
Predicted Functional Partners:
essD
DLP12 prophage; putative phage lysis protein.
  
  
 0.978
rrrD
DLP12 prophage; Essential for lysis of bacterial cell wall, by showing cell wall hydrolyzing activity. Exhibits lytic activity against E.coli and S.typhi cell wall substrate; Belongs to the glycosyl hydrolase 24 family.
  
  
 0.909
rzoD
DLP12 prophage; Component of the spanin complex that disrupts the outer membrane and causes cell lysis during virus exit. The spanin complex conducts the final step in cell lysis by disrupting the outer membrane after holin and endolysin action have permeabilized the inner membrane and degraded the host peptidoglycans (By similarity); Belongs to the lambdalikevirus o-spanin family.
      
 0.816
yfjZ
CP4-57 prophage; Antitoxin component of a type IV toxin-antitoxin (TA) system. Antitoxin that counteracts the effect of cognate toxin YpjF. Also counteracts the effect of non-cognate toxins CbtA and YfkI.
   
  
 0.809
quuD
DLP12 prophage; Positively regulate expression of some phage genes. Bacterial host RNA polymerase modified by antitermination proteins transcribes through termination sites that otherwise prevent expression of the regulated genes (By similarity); Belongs to the phage antitermination Q type 1 family.
   
  
 0.807
alpA
CP4-57 prophage; Positive regulator of the expression of the slpA gene. When overexpressed, leads to suppression of the capsule overproduction and UV sensitivity phenotypes of cells mutant for the Lon ATP-dependent protease. Part of the cryptic P4-like prophage CP4-57. Overexpression of AlpA leads to excision of the CP4-57 prophage by IntA. This inactivates ssrA (the gene upstream of the prophage) that encodes tmRNA which is required to rescue stalled ribosomes in a process known as trans- translation.
   
  
 0.783
appY
HTH-type transcriptional regulator AppY; Induces the synthesis of acid phosphatase (AppA) and several other polypeptides (such as AppBC) during the deceleration phase of growth. It also acts as a transcriptional repressor for one group of proteins that are synthesized preferentially in exponential growth and for one group synthesized only in the stationary phase. Also involved in the stabilization of the sigma stress factor RpoS during stress conditions.
      
 0.731
hha
Modulator of gene expression, with H-NS; Down-regulates hemolysin (hly) expression in complex with H- NS. Stimulates transposition events in vivo. Modifies the set of genes regulated by H-NS; Hha and Cnu (YdgT) increase the number of genes DNA bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex. Binds DNA and influences DNA topology in response to environmental stimuli; does not however interact with DNA in the absence of H-NS. Involved in persister cell formation, acting downstream of mRNA interferase (toxin) MqsR. Decreases biofilm formation by repre [...]

emrE
DLP12 prophage; Multidrug transporter that expels positively charged hydrophobic drugs across the inner membrane of E.coli., thereby conferring resistance to a wide range of toxic compounds. The drug efflux is coupled to an influx of protons. Is involved in the resistance of E.coli cells to methyl viologen, ethidium bromide and acriflavine. Is also able to transport tetraphenylphosphonium (TPP(+)) and benzalkonium. Belongs to the drug/metabolite transporter (DMT) superfamily. Small multidrug resistance (SMR) (TC 2.A.7.1) family.
      
 0.638
tomB
Hha toxicity attenuator; Attenuates Hha toxicity and regulates biofilm formation. Binds to various coding and intergenic regions of genomic DNA.
