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

dacDD-alanyl-D-alanine carboxypeptidase; Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors; Belongs to the peptidase S11 family. (388 aa)    
Predicted Functional Partners:
dacB
D-alanyl-D-alanine carboxypeptidase; Not involved in transpeptidation but exclusively catalyzes a DD-carboxypeptidase and DD-endopeptidase reaction. Belongs to the peptidase S13 family.
     
 0.990
yfeW
Penicillin binding protein PBP4B; Penicillin-binding protein. Has low DD-carboxypeptidase activity; Belongs to the peptidase S12 family. YfeW subfamily.
     
 0.988
mrcA
Penicillin-binding protein 1a, murein transglycosylase and transpeptidase; Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross- linking of the peptide subunits); In the N-terminal section; belongs to the glycosyltransferase 51 family.
     
 0.979
dacA
D-alanyl-D-alanine carboxypeptidase (penicillin-binding protein 5); Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors.
  
  
0.911
dacC
D-alanyl-D-alanine carboxypeptidase; Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors.
  
  
0.910
pbpC
Penicillin-insensitive murein repair transglycosylase; Cell wall formation. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a transpeptidase C-terminal domain which may not be functional.
     
 0.897
mrcB
Fused glycosyl transferase and transpeptidase; Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross- linking of the peptide subunits); In the N-terminal section; belongs to the glycosyltransferase 51 family.
   
 
 0.871
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. Belongs to the transpeptidase family. MrdA subfamily.
  
 0.833
ampH
D-alanyl-D-alanine- carboxypeptidase/endopeptidase; Hydrolyzes the cross-linked dimers tetrapentapeptide (D45) and tetratetrapeptide (D44). Removes the terminal D-alanine from muropeptides and disaccharide pentapeptide M5 with a C-terminal D-Ala- D-Ala dipeptide. Associated with recycling and remodeling of peptidoglycan (PG). Also displays a low beta-lactamase activity. Belongs to the beta-lactamase family.
      
 0.815
ldtD
Murein L,D-transpeptidase; Responsible, at least in part, for generating a meso- diaminopimelyl-3-a meso-diaminopimelyl-3 cross-link. Belongs to the YkuD family.
