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

mraZPutative protein involved in cell division or replication; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type cp: cell process; Belongs to the MraZ family. (143 aa)    
Predicted Functional Partners:
mraW
S-adenosyl-dependent methyltransferase active on membrane-located substrates; Specifically methylates the N4 position of cytidine in position 1402 (C1402) of 16S rRNA.
  
 0.999
ftsL
Cell-division protein; Essential cell division protein that may play a structural role. Probably involved in the regulation of the timing of cell division. Also required for sporulation.
  
  
 0.863
ytqB
Putative RNA methylase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the methyltransferase superfamily.
  
  
 0.820
pbpB
Penicillin-binding protein 2B; Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. PBP-2B is required for vegetative cell division and sporulation septation. Beta-lactamase inactivates the PBPs by acylating an essential serine residue in the active site of these proteins, thereby interrupting normal cell wall synthesis; Belongs to the transpeptidase family.
 
  
 0.802
ftsZ
Cell-division initiation protein; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
  
  
 0.738
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.
  
  
 0.724
ftsA
Cell-division protein essential fo Z-ring assembly; Cell division protein that is required for the assembly of the Z ring. May serve as a membrane anchor for the Z ring (By similarity). Binds and hydrolyzes ATP. Also involved in sporulation (Probable). Belongs to the FtsA/MreB family.
 
  
 0.719
spoIIIE
Spore DNA translocase; Plays an essential role during sporulation. Required for the translocation of the chromosomal DNA from mother cell into the forespore during polar septation, for the final steps of compartmentalization in the presence of trapped DNA, and for the final steps of engulfment. The N-terminus mediates localization to the division septum and is required for both septal membrane fusion and engulfment membrane fusion. May form DNA-conducting channels across the two lipid bilayers of the septum after cell division. The C-terminus functions as a DNA motor that exports DNA i [...]

ndoAI
Antitoxin EndoAI; Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that directly inhibits activity of EndoA in vitro. Upon expression in E.coli counteracts inhibitory effect of endoribonuclease EndoA. The EndoA-EndoAI complex does not seem to bind its own promoter.
   
  
 0.689
murD
UDP-N-acetylmuramoylalanyl-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.
