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

ampEAmpicillin resistance inner membrane protein; Putative signaling protein in beta-lactamase regulation. AmpE seems not to act as a direct sensor for beta-lactams. (284 aa)    
Predicted Functional Partners:
ampD
1,6-anhydro-N-acetylmuramyl-L-alanine amidase, Zn-dependent; Involved in cell wall peptidoglycan recycling. Specifically cleaves the amide bond between the lactyl group of N-acetylmuramic acid and the alpha-amino group of the L-alanine in degradation products containing an anhydro N-acetylmuramyl moiety. Is also involved in beta-lactamase induction ; Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family.
  
  
 0.984
ampG
Muropeptide transporter; Permease involved in cell wall peptidoglycan recycling. Transports, from the periplasm into the cytoplasm, the disaccharide N-acetylglucosaminyl-beta-1,4-anhydro- N-acetylmuramic acid (GlcNAc-anhMurNAc) and GlcNAc-anhMurNAc-peptides. Transport is dependent on the proton motive force. AmpG is also involved in beta-lactamase induction ; Belongs to the major facilitator superfamily.
     
 0.878
ampC
Penicillin-binding protein; This protein is a serine beta-lactamase with a substrate specificity for cephalosporins; Belongs to the class-C beta-lactamase family.
      
 0.809
yhfK
Putative transporter, FUSC superfamily inner membrane protein; Protein involved in metabolic process.
  
     0.755
yeeA
Putative transporter, FUSC family inner membrane protein.
  
     0.752
tsgA
Putative transport; Belongs to the major facilitator superfamily. TsgA family.
  
     0.733
opgC
OPG biosynthetic transmembrane succinyltransferase; Necessary for the succinyl substitution of periplasmic glucans. Could catalyze the transfer of succinyl residues from the cytoplasmic side of the membrane to the nascent glucan backbones on the periplasmic side of the membrane.
  
     0.728
ycdY
Redox enzyme maturation protein (REMP) chaperone for YcdX; Acts as a chaperone that increases YcdX activity, maybe by facilitating the correct insertion of the zinc ions into the catalytic site of YcdX. Involved in the swarming motility process.
  
     0.720
nadC
Quinolinate phosphoribosyltransferase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
     
 0.709
rcsD
Phosphotransfer intermediate protein in two-component regulatory system with RcsBC; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsD is a phosphotransfer intermediate between the sensor kinase RcsC and the response regulator RcsB. It acquires a phosphoryl group from RcsC and transfers it to RcsB. The system controls expression of genes involved in colanic acid capsule synthesis, biofilm formation and cell division.
