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

mrcBTranspeptidase of penicillin-binding protein 1b; 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). (840 aa)    
Predicted Functional Partners:
ftsI
Division specific transpeptidase; Catalyzes cross-linking of the peptidoglycan cell wall at the division septum.
 
 
 
 0.981
ycfM
Putative outer membrane lipoprotein; Regulator of peptidoglycan synthesis that is essential for the function of penicillin-binding protein 1B (PBP1b).
  
 
 
 0.980
ftsI-2
Putative penicillin-binding protein-3; Catalyzes cross-linking of the peptidoglycan cell wall at the division septum.
 
 
 
 0.979
mrdA
Cell elongation specific transpeptidase of penicillin-binding protein 2 (peptidoglycan synthetase); Catalyzes cross-linking of the peptidoglycan cell wall. Belongs to the transpeptidase family. MrdA subfamily.
 
 
 
 0.976
mrdA-2
Putative penicillin-binding protein; Catalyzes cross-linking of the peptidoglycan cell wall. Belongs to the transpeptidase family. MrdA subfamily.
 
 
 
 0.973
mrcA
Similar to E. coli peptidoglycan synthetase; penicillin-binding protein 1A (AAC76421.1); Blastp hit to AAC76421.1 (858 aa), 92% identity in aa 1 - 858.
 
 
0.966
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.
  
 
 0.954
ftsW
Essential cell division gene; Peptidoglycan polymerase that is essential for cell division. Belongs to the SEDS family. FtsW subfamily.
 
 
 
 0.928
pbpC
Transglycosylase of penicillin-binding protein 1c; Similar to E. coli putative peptidoglycan enzyme (AAC75572.1); Blastp hit to AAC75572.1 (770 aa), 82% identity in aa 7 - 767.
  
  
0.916
yafK
Putative periplasmic protein; Similar to E. coli orf, hypothetical protein (AAC73328.1); Blastp hit to AAC73328.1 (246 aa), 90% identity in aa 1 - 246.
