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:
some 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

quuDDLP12 prophage; putative antitermination protein; 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) (127 aa)    
Predicted Functional Partners:
rzpD
DLP12 prophage; putative prophage endopeptidase RzpD; 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)

essD
DLP12 prophage; putative phage lysis protein; Prophage lysis protein S homolog EssD; Phage or Prophage Related
      
 0.878
rzoD
DLP12 prophage; putative prophage lysis lipoprotein RzoD; 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)

ratA
Toxic upf0083 family protein inhibitor of 70s ribosome formation; Toxic component of a type II toxin-antitoxin (TA) system. Binds to 50S ribosomal subunits, preventing them from associating with 30S subunits to form 70S ribosomes and reducing polysomes. It does not cause ribosomes to dissociate however. The antibiotic paromomycin blocks the anti-association activity of RatA. Overexpression results in inhibition of growth in liquid cultures, and in a decrease in protein translation. The other gene of this operon, ratB, is not the cognate antitoxin in this strain; in CFT073 however it do [...]

rusA
DLP12 prophage; crossover junction endodeoxyribonuclease RusA; Endonuclease that resolves Holliday junction intermediates made during homologous genetic recombination and DNA repair. Exhibits sequence and structure-selective cleavage of four-way DNA junctions, where it introduces symmetrical nicks in two strands of the same polarity at the 5' side of CC dinucleotides. Corrects the defects in genetic recombination and DNA repair associated with inactivation of ruvAB or ruvC

nanC
Outer membrane channel protein allowing the entry of N- acetylneuraminic acid (Neu5Ac, the most abundant sialic acid on host cell surfaces) into the bacteria (Probable). NanC proteins form high- conductance channels which are open at low membrane potentials and which have a weak anion selectivity

hha
Haemolysin expression modulating protein; 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 [...]

yfeN
Conserved outer membrane protein yfen; Belongs to the nucleoside-specific channel-forming outer membrane porin (Tsx) (TC 1.B.10) family
  
    0.665
ybcO
DLP12 prophage; putative nuclease YbcO; Based on its fold and a conserved His residue, has been predicted to be a nuclease

yihF
Uncharacterized protein yihf; To E.coli YdgA and H.influenzae HI_1236
