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

ddlAD-alanine-D-alanine ligase A; Cell wall formation. (364 aa)    
Predicted Functional Partners:
murF
UDP-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.
 
 0.993
murC
UDP-N-acetylmuramate:L-alanine ligase; Cell wall formation; Belongs to the MurCDEF family.
  
 0.993
alr
Alanine racemase, biosynthetic, PLP-binding; Catalyzes the interconversion of L-alanine and D-alanine. Provides the D-alanine required for cell wall biosynthesis.
 
 
 0.986
dadX
Alanine racemase, catabolic, PLP-binding; Isomerizes L-alanine to D-alanine which is then oxidized to pyruvate by DadA.
 
 
 0.981
ddlB
D-alanine:D-alanine ligase; Cell wall formation; Belongs to the D-alanine--D-alanine ligase family.
  
  
0.919
murD
UDP-N-acetylmuramoyl-L-alanine:D-glutamate ligase; Cell wall formation. Catalyzes the addition of glutamate to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanine (UMA).
 
  
 0.870
murG
N-acetylglucosaminyl 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).
 
  
 0.848
mraY
phospho-N-acetylmuramoyl-pentapeptide transferase; First step of the lipid cycle reactions in the biosynthesis of the cell wall peptidoglycan.
 
  
 0.832
murE
UDP-N-acetylmuramoyl-L-alanyl-D-glutamate:meso- 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.
 
  
 0.799
murB
UDP-N-acetylenolpyruvoylglucosamine reductase, FAD-binding; Cell wall formation; Belongs to the MurB family.
 
  
 0.799
