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

ftsNCell division protein FtsN; 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. (275 aa)    
Predicted Functional Partners:
ftsA
Cell division protein; Cell division protein that is involved in the assembly of the Z ring. May serve as a membrane anchor for the Z ring. Belongs to the FtsA/MreB family.
   
 
 0.847
ftsQ
Cell division protein; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic. May control correct divisome assembly.
 
 
 
 0.810
menG
S-adenosylmethionine:2-demethylmenaquinone methyltransferase; 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.
      0.804
mrcB
Penicillin-binding protein 1B; Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross- linking of the peptide subunits).
  
 
 
 0.782
holD
DNA polymerase III, psi subunit; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The exact function of the psi subunit is unknown.
  
    0.772
dsbA
Disulfide interchange protein DsbA precursor.
 
     0.770
lpoB
Penicillin-binding protein activator LpoB; Regulator of peptidoglycan synthesis that is essential for the function of penicillin-binding protein 1B (PBP1b).
  
   
 0.729
helD
DNA helicase IV.
  
     0.728
smp
Protein Smp precursor.
  
     0.725
ftsI
Peptidoglycan synthetase ftsI precursor (penicillin-binding protein 3) (PBP-3); Catalyzes cross-linking of the peptidoglycan cell wall at the division septum; Belongs to the transpeptidase family. FtsI subfamily.
