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

mtgABiosynthetic peptidoglycan transglycosylase; Peptidoglycan polymerase that catalyzes glycan chain elongation from lipid-linked precursors. May play a role in peptidoglycan assembly during cell division in collaboration with other cell division proteins ; Belongs to the glycosyltransferase 51 family. (242 aa)    
Predicted Functional Partners:
ftsI
Transpeptidase involved in septal peptidoglycan synthesis; Essential cell division protein that catalyzes cross-linking of the peptidoglycan cell wall at the division septum. Required for localization of FtsN. Belongs to the transpeptidase family. FtsI subfamily.
 
 0.965
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.
 
  
 0.949
ftsW
Putative lipid II flippase; 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.
  
 
 
 0.849
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.
  
  
0.849
mrdB
Cell wall shape-determining protein; Peptidoglycan polymerase that is essential for cell wall elongation. Also required for the maintenance of the rod cell shape. Functions probably in conjunction with the penicillin-binding protein 2 (mrdA).
  
   
 0.843
ftsN
Essential cell division protein; Essential cell division protein that activates septal peptidoglycan synthesis and constriction of the cell. Acts on both sides of the membrane, via interaction with FtsA in the cytoplasm and interaction with the FtsQBL complex in the periplasm. These interactions may induce a conformational switch in both FtsA and FtsQBL, leading to septal peptidoglycan synthesis by FtsI and associated synthases (Probable). Required for full FtsI activity. Required for recruitment of AmiC to the septal ring. Belongs to the FtsN family.
   
 
 0.832
elbB
Isoprenoid biosynthesis protein with amidotransferase-like domain; Displays glyoxalase activity, catalyzing the conversion of glyoxal to glycolate. However, this apparent glyoxalase activity may reflect a protein deglycase activity, which could be the primary function of this protein like other DJ-1 superfamily members such as PARK7, YajL, YhbO and HchA (Probable). Is not able to use methylglyoxal as substrate. Belongs to the peptidase C56 family.
  
    0.807
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.
  
  
 0.759
murJ
Putative lipid II flippase; Involved in peptidoglycan biosynthesis. Transports lipid- linked peptidoglycan precursors from the inner to the outer leaflet of the cytoplasmic membrane. Belongs to the MurJ/MviN family.
     
 0.752
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.
