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

lpoAAntigen; Regulator of peptidoglycan synthesis that is essential for the function of penicillin-binding protein 1A (PBP1a). (575 aa)    
Predicted Functional Partners:
mrcA
Penicillin-binding protein 1A (ponA); 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).
  
 
 
 0.934
HI_1656
Conserved hypothetical protein; Similar to SP:P45465 PID:606088 GB:U00096 PID:1789538 percent identity: 48.67; identified by sequence similarity; putative; Belongs to the UPF0102 family.
 
   
 0.830
HI_1657
Conserved hypothetical protein; Similar to SP:P45466 PID:606089 GB:U00096 PID:1789539 percent identity: 35.26; identified by sequence similarity; putative; Belongs to the SIS family. DiaA subfamily.
  
    0.784
hemY
hemY protein (hemY); Involved in a late step of protoheme IX synthesis.
  
     0.718
mrcB
Penicillin-binding protein 1B (ponB); 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) (By similarity).
      
 0.708
lolB
hemM protein (hemM); Plays a critical role in the incorporation of lipoproteins in the outer membrane after they are released by the LolA protein.
  
   
 0.685
zipA
Cell division protein ZipA, putative; Essential cell division protein that stabilizes the FtsZ protofilaments by cross-linking them and that serves as a cytoplasmic membrane anchor for the Z ring. Also required for the recruitment to the septal ring of downstream cell division proteins.
  
     0.684
matP
Conserved hypothetical protein; Required for spatial organization of the terminus region of the chromosome (Ter macrodomain) during the cell cycle. Prevents early segregation of duplicated Ter macrodomains during cell division. Binds specifically to matS, which is a 13 bp signature motif repeated within the Ter macrodomain.
  
     0.649
trpR
Trp operon repressor (trpR); This protein is an aporepressor. When complexed with L- tryptophan it binds the operator region of the trp operon and prevents the initiation of transcription (By similarity).
  
     0.646
recX
Regulatory protein (recX); Modulates RecA activity; Belongs to the RecX family.
  
     0.645
