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

murFUdp-n-acetylmuramoyl-tripeptide--d-alanyl-d-alanine ligase; Involved in cell wall formation. Catalyzes the final step in the synthesis of UDP-N-acetylmuramoyl-pentapeptide, the precursor of murein (452 aa)    
Predicted Functional Partners:
murE
UDP-N-acetylmuramoyl-L-alanyl-D-glutamate--2,6-diaminopimelate ligase; Catalyzes the addition of meso-diaminopimelic acid to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanyl-D-glutamate (UMAG) in the biosynthesis of bacterial cell-wall peptidoglycan. Is also able to use many meso-diaminopimelate analogs as substrates, although much less efficiently, but not L-lysine
0.999
mraY
Phospho-n-acetylmuramoyl-pentapeptide-transferase; First step of the lipid cycle reactions in the biosynthesis of the cell wall peptidoglycan
 
 0.999
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)
  
 0.999
murC
Udp-n-acetylmuramate--l-alanine ligase; Cell wall formation
 
 0.999
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
 
 0.998
ftsW
Putative lipid ii flippase ftsw; Peptidoglycan polymerase that is essential for cell division (Probable). Functions probably in conjunction with the penicillin- binding protein 3 (ftsI) . Required for localization of FtsI
  
 0.998
ddlB
D-alanine--d-alanine ligase b; Cell wall formation
 
 0.998
mraZ
Dna-binding transcriptional repressor mraz; Negatively regulates its own expression and that of the subsequent genes in the proximal part of the division and cell wall (dcw) gene cluster. Acts by binding directly to DNA. May also regulate the expression of genes outside the dcw cluster
 
 
 0.989
rsmH
16S rRNA m(4)C1402 methyltransferase, SAM-dependent; Specifically methylates the N4 position of cytidine in position 1402 (C1402) of 16S rRNA. In vitro, active on the assembled 30S subunit, but not naked 16S rRNA or 70S ribosomes
  
 0.988
ftsL
Membrane bound cell division leucine zipper septum 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. Can also mediate Zn(2+)-sensitivity probably by increasing the permeability of the inner membrane
