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

penAPenicillin-binding protein 2; Catalyzes cross-linking of the peptidoglycan cell wall at the division septum. (581 aa)    
Predicted Functional Partners:
murE
UDP-N-acetylmuramoylalanyl-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.
  
 0.993
ftsW
Cell division protein FtsW; Peptidoglycan polymerase that is essential for cell division. Belongs to the SEDS family. FtsW subfamily.
 
 0.992
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.
 
 
 0.965
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.
  
  
 0.879
parC
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.
  
  
 0.879
rsmH
Conserved hypothetical protein; Specifically methylates the N4 position of cytidine in position 1402 (C1402) of 16S rRNA.
  
  
 0.876
murF
UDP-N-acetylmuramoylalanyl-D-glutamyl-2, 6-diaminopimelate--D-alanyl-D-alanyl 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.
 
  
 0.875
murC
UDP-N-acetylmuramate--alanine ligase; Cell wall formation; Belongs to the MurCDEF family.
 
 
 0.867
murD
UDP-N-acetylmuramoylalanine--D-glutamate ligase; Cell wall formation. Catalyzes the addition of glutamate to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanine (UMA). Belongs to the MurCDEF family.
 
  
 0.855
mraZ
Conserved hypothetical protein; Identified by similarity to EGAD:6617; match to protein family HMM PF02381; match to protein family HMM TIGR00242; Belongs to the MraZ family.
