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

mrdBCell wall shape-determining protein; Peptidoglycan polymerase that is essential for cell wall elongation . Also required for the maintenance of the rod cell shape . Functions probably in conjunction with the penicillin-binding protein 2 (mrdA) (370 aa)    
Predicted Functional Partners:
mrdA
Penicillin-binding protein 2, transpeptidase involved in peptidoglycan synthesis; Catalyzes cross-linking of the peptidoglycan cell wall . Responsible for the determination of the rod shape of the cell . Is probably required for lateral peptidoglycan synthesis and maintenance of the correct diameter during lateral and centripetal growth

mreC
Cell wall structural complex mrebcd transmembrane component mrec; Involved in formation and maintenance of cell shape. Responsible for formation of rod shape. May also contribute to regulation of formation of penicillin-binding proteins
 
 
 0.997
mreB
Cell wall structural complex mrebcd, actin-like component mreb; 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 MreB localization maintains elongated cell shape by targeting cell wall growth to regions of negative cell wall curvature . 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 MreB polym [...]

mreD
Cell wall structural complex mrebcd transmembrane component mred; Involved in formation of the rod shape of the cell. May also contribute to regulation of formation of penicillin-binding proteins
 
  
 0.994
rlpA
Septal ring protein, suppressor of prc, minor lipoprotein; Lytic transglycosylase with a strong preference for naked glycan strands that lack stem peptides
 
  
 0.988
rodZ
Transmembrane component of cytoskeleton; Cytoskeletal protein that is involved in cell-shape control through regulation of the length of the long axis
  
  
 0.984
murG
Udp-n-acetylglucosamine--n-acetylmuramyl-(pentapeptide) pyrophosphoryl-undecaprenol n-acetylglucosamine transferase; Cell wall formation. Catalyzes the transfer of a GlcNAc subunit on undecaprenyl-pyrophosphoryl-MurNAc-pentapeptide (lipid intermediate I) to form undecaprenyl-pyrophosphoryl-MurNAc- (pentapeptide)GlcNAc (lipid intermediate II)
 
 0.979
ftsI
Cell division protein ftsi (penicillin-binding protein 3); Essential cell division protein that catalyzes cross-linking of the peptidoglycan cell wall at the division septum Required for localization of FtsN
 
 0.968
ftsZ
Gtp-binding tubulin-like cell division 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. Polymerization and bundle formation is enhanced by CbeA
  
 
 0.958
murJ
Putative peptidoglycan lipid ii flippase; Involved in peptidoglycan biosynthesis. Transports lipid- linked peptidoglycan precursors from the inner to the outer leaflet of the cytoplasmic membrane
