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

penA_1Penicillin-binding protein; Catalyzes cross-linking of the peptidoglycan cell wall at the division septum; Belongs to the transpeptidase family. FtsI subfamily. (588 aa)    
Predicted Functional Partners:
murE
UDP-N-acetylmuramoyl-L-alanyl-D-glutamate--2, 6-diaminopimelate ligase; Catalyzes the addition of meso-diaminopimelic acid to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanyl-D-glutamate (UMAG) in the biosynthesis of bacterial cell-wall peptidoglycan. Belongs to the MurCDEF family. MurE subfamily.
  
 0.986
ftsW
Putative lipid II flippase FtsW; Peptidoglycan polymerase that is essential for cell division. Belongs to the SEDS family. FtsW subfamily.
 
 0.978
penA_2
Penicillin-binding protein 2; Catalyzes cross-linking of the peptidoglycan cell wall. Belongs to the transpeptidase family. MrdA subfamily.
  
  
0.952
ftsL
Cell division protein FtsL; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic.
  
 
 0.948
ftsQ
Cell division protein FtsQ; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic. May control correct divisome assembly.
 
 
 0.922
mrdB
Rod shape-determining protein RodA; Peptidoglycan polymerase that is essential for cell wall elongation; Belongs to the SEDS family. MrdB/RodA subfamily.
 
 0.906
gyrA
DNA gyrase subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
  
  
 0.903
parC
DNA topoisomerase IV subunit A; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily.
  
  
 0.903
murF
UDP-N-acetylmuramoyl-tripeptide--D-alanyl-D- alanine ligase; Involved in cell wall formation. Catalyzes the final step in the synthesis of UDP-N-acetylmuramoyl-pentapeptide, the precursor of murein; Belongs to the MurCDEF family. MurF subfamily.
 
  
 0.862
rplD
50S ribosomal protein L4; Forms part of the polypeptide exit tunnel.
      
 0.857
