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

pbpAPenicillin-binding protein 1A; Cell wall formation; In the C-terminal section; belongs to the transpeptidase family. (719 aa)    
Predicted Functional Partners:
pbpX
Penicillin-binding protein 2X; Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. Beta-lactams inactivate the PBPs by acylating an essential serine residue in the active site of these proteins.
 
 0.999
pbp2b
Penicillin-binding protein 2B.
 
 0.998
pbp2a
Penicillin-binding protein 2a.
  
 
0.953
pbp1b
Penicillin-binding protein 1b.
  
  
0.953
gpsB
Conserved hypothetical protein; Divisome component that associates with the complex late in its assembly, after the Z-ring is formed, and is dependent on DivIC and PBP2B for its recruitment to the divisome. Together with EzrA, is a key component of the system that regulates PBP1 localization during cell cycle progression. Its main role could be the removal of PBP1 from the cell pole after pole maturation is completed. Also contributes to the recruitment of PBP1 to the division complex. Not essential for septum formation.
 
 
 
 0.950
recU
Recombination protein U; Endonuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves mobile four-strand junctions by introducing symmetrical nicks in paired strands. Promotes annealing of linear ssDNA with homologous dsDNA. Required for DNA repair, homologous recombination and chromosome segregation (By similarity). Belongs to the RecU family.
  
  
 0.920
dacA
D-alanyl-D-alanine carboxypeptidase; Belongs to the peptidase S11 family.
  
 
 0.918
rodA
Rod shape determining protein; Belongs to the SEDS family.
 
 
 
 0.904
spr0554
Conserved hypothetical protein; Putative carboxypeptidase.
     
 0.903
mreC
Cell shape determining protein MreC; Involved in formation and maintenance of cell shape.
  
 
 0.845
