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

pinESerine recombinase PinE; This protein catalyzes the inversion of an 1800-bp E.coli DNA fragment, the P region, which can exist in either orientation. The function of the inversion is not yet clear. (184 aa)    
Predicted Functional Partners:
tfaE
E14 prophage; putative tail fiber assembly protein.

yhcG
DUF1016 family protein in the PD-(D/E)XK nuclease superfamily; May be a nuclease involved in DNA recombination and repair.
  
  
 0.670
ompA
Outer membrane protein A (3a;II*;G;d); With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm (Probable). Plays a role in resistance to environmental stress, and a role in outer membrane functionality and cell shape. Non-covalently binds peptidoglycan (Probable). Acts as a porin with low permeability that allows slow penetration of small solutes. A very abundant protein, there can be up to 210,000 OmpA molecules per cell. Reconstitution in unilamellar lipid vesicles shows only about 3% of the protein is in an open conformation, whic [...]

stfP
E14 prophage; uncharacterized protein; To E.coli YfdL and M.jannaschii MJ0347.

tfaP
E14 prophage; uncharacterized protein; To E.coli YfdK.

mcrA
Putative 5-methylcytosine/5-hydroxymethylcytosine-specific restriction nuclease; Restriction of 5-methyl and 5-hydroxymethylcytosines at the specific DNA sequence C(me)CGG.
  
    0.524
yahD
Ankyrin repeat protein; Putative transcription factor.
      
 0.457
lpp
Murein lipoprotein; An outer membrane lipoprotein that controls the distance between the inner and outer membranes; adding residues to Lpp increases the width of the periplasm. The only protein known to be covalently linked to the peptidoglycan network (PGN). Also non-covalently binds the PGN. The link between the cell outer membrane and PGN contributes to the maintenance of the structural and functional integrity of the cell envelope, and maintains the correct distance between the PGN and the outer membrane. The most adundant cellular protein, there can be up to 10(6) Lpp molecules pe [...]
