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

mreBHCell-shape determining protein; Forms membrane-associated dynamic filaments that are essential for cell shape determination. Acts by regulating cell wall synthesis and cell elongation, and thus cell shape. A feedback loop between cell geometry and MreBH localization may maintain elongated cell shape by targeting cell wall growth to regions of negative cell wall curvature (By similarity). Filaments rotate around the cell circumference in concert with the cell wall synthesis enzymes. The process is driven by the cell wall synthesis machinery and does not depend on MreBH polymerization.

Predicted Functional Partners:
mreC
Cell-shape determining protein; Involved in formation and maintenance of cell shape. Required for the formation of proper helical filaments of MreB and for cell wall synthesis in the cylindrical part of the cell leading to cell elongation; Belongs to the MreC family.
 
 
 0.990
lytE
Cell wall hydrolase; Cell wall hydrolase that cleaves gamma-D-glutamate-meso- diaminopimelate bonds in peptidoglycan (By similarity). Seems to play a role in cell separation during vegetative growth.
 
  
 0.953
rodA
Factor involved in extension of the lateral walls of the cell; Peptidoglycan polymerase that is essential for cell wall elongation. Also required for the maintenance of the rod cell shape. Belongs to the SEDS family. MrdB/RodA subfamily.
 
 
 0.952
mreD
Cell-shape determining protein; Involved in formation of the rod shape of the cell. May also contribute to regulation of formation of penicillin-binding proteins (By similarity).
  
  
 0.936
pbpH
Penicillin-binding enzyme for formation of rod-shaped peptidoglycan cell wall; Involved in the polymerization of peptidoglycan. Plays a redundant role with PBP2a in determining the rod shape of the cell during vegetative growth and spore outgrowth. Belongs to the transpeptidase family.
 
 
 0.865
ymfM
Conserved hypothetical protein with ACT domain; Evidence 7: Gene remnant.
 
 
 0.857
ftsZ
Cell-division initiation protein; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
  
 
 0.837
ykpC
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
    0.815
rsgI
sigmaI modulating factor; Anti-sigma factor for SigI. Negatively regulates SigI activity through direct interaction.
  
  
 0.805
sigI
RNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of cell wall metabolism in response to heat stress. Acts by regulating the expression of genes such as bcrC, mreBH and lytE. Also plays a role in survival at low temperatures. Belongs to the sigma-70 factor family. SigI subfamily.
