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

ldtEMurein l,d-transpeptidase; Responsible, at least in part, for generating a meso- diaminopimelyl-3-a meso-diaminopimelyl-3 cross-link (334 aa)    
Predicted Functional Partners:
dacC
Serine-type d-ala-d-ala carboxypeptidase (penicillin-binding protein 5/6); Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors
   
 
 0.952
dacA
Serine-type d-ala-d-ala carboxypeptidase (penicillin-binding protein 5/6); Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors
     
 0.946
ampH
Peptidoglycan dd-carboxypeptidase/peptidoglycan dd-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
     
 0.945
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)
     
 0.939
ldtD
Murein l,d-transpeptidase; Responsible, at least in part, for generating a meso- diaminopimelyl-3-a meso-diaminopimelyl-3 cross-link
 
  
 0.933
mrcB
Peptidoglycan glycosyltransferase/peptidoglycan dd-transpeptidase mrcb; 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)
     
 0.925
dacD
Serine-type d-ala-d-ala carboxypeptidase (penicillin-binding protein 5/6); Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors
     
 0.924
yafK
annotation not available
 
   
 0.907
yfeW
Serine-type d-ala-d-ala carboxypeptidase; Penicillin-binding protein. Has low DD-carboxypeptidase activity
     
 0.905
yeaG
Protein kinase, endogenous substrate unidentified; Belongs to the PrkA family
   
    0.777
