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

ddLD-ala,D-ala ligase; Cell wall formation; Belongs to the D-alanine--D-alanine ligase family. (347 aa)    
Predicted Functional Partners:
murF
UDP-N-acetylmuramoylalanyl-D-glutamyl-2, 6-diaminopimelate--D-alanyl-D-alanyl ligase; Involved in cell wall formation. Catalyzes the final step in the synthesis of UDP-N-acetylmuramoyl-pentapeptide, the precursor of murein; Belongs to the MurCDEF family. MurF subfamily.
 
 0.997
murC
UDP-N-acetylmuramate-alanine ligase; Cell wall formation; Belongs to the MurCDEF family.
  
 0.980
murB
UDP-N-acetylenolpyruvoylglucosamine reductase; Cell wall formation.
  
 0.964
smi_0593
Alanine racemase; Catalyzes the interconversion of L-alanine and D-alanine. May also act on other amino acids; Belongs to the alanine racemase family.
 
 
 0.958
dltA
D-alanine:Dcp ligase Dcl; Catalyzes the first step in the D-alanylation of lipoteichoic acid (LTA), the activation of D-alanine and its transfer onto the D- alanyl carrier protein (Dcp) DltC. In an ATP-dependent two-step reaction, forms a high energy D-alanyl-AMP intermediate, followed by transfer of the D-alanyl residue as a thiol ester to the phosphopantheinyl prosthetic group of the Dcp. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram-positive bacteria, influencing the net charge of the cell wall. Belongs to the ATP-dependent AMP-bi [...]
   
 
 0.919
dltC
D-alanyl carrier protein DCP; Carrier protein involved in the D-alanylation of lipoteichoic acid (LTA). The loading of thioester-linked D-alanine onto DltC is catalyzed by D-alanine--D-alanyl carrier protein ligase DltA. The DltC- carried D-alanyl group is further transferred to cell membrane phosphatidylglycerol (PG) by forming an ester bond, probably catalyzed by DltD. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram-positive bacteria, influencing the net charge of the cell wall.

pbp2B
Penicillin-binding protein 2B.
 
 
 0.877
murD
MurD D-glutamic acid adding enzyme; Cell wall formation. Catalyzes the addition of glutamate to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanine (UMA). Belongs to the MurCDEF family.
 
  
 0.847
recR
Recombination protein; May play a role in DNA repair. It seems to be involved in an RecBC-independent recombinational process of DNA repair. It may act with RecF and RecO.
 
   
 0.794
pbp2x
Penicillin-binding protein 2X.
 
 
 0.783
