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

pbpATranspeptidase (penicillin-binding protein 2A); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme. (716 aa)    
Predicted Functional Partners:
rodA
Factor involved in extension of the lateral walls of the cell; Peptidoglycan polymerase that is essential for cell wall elongation. Also required for the maintenance of the rod cell shape. Belongs to the SEDS family. MrdB/RodA subfamily.
 
 0.969
pbpF
Penicillin-binding protein 2C required for spore germination; Cell wall formation. May be involved in outgrowth of the germinated spore or it could function in the synthesis of the germ cell wall; In the N-terminal section; belongs to the glycosyltransferase 51 family.
 
 
 
 0.902
ponA
Peptidoglycan glycosyltransferase (penicillin-binding proteins 1A and 1B); 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).
 
 
 0.890
mreC
Cell-shape determining protein; Involved in formation and maintenance of cell shape. Required for the formation of proper helical filaments of MreB and for cell wall synthesis in the cylindrical part of the cell leading to cell elongation; Belongs to the MreC family.
 
 
 0.873
divIB
Cell-division initiation protein; Cell division protein that may be involved in stabilizing or promoting the assembly of the division complex. Plays an essential role in division at high temperatures, maybe by protecting FtsL from degradation or by promoting formation of the FtsL-DivIC complex. May modulate the transpeptidase activity of PBP-2B. Also required for efficient sporulation at all temperatures. Could be directly involved in the engulfment process or be required to form a sporulation septum competent for engulfment. Influences the Spo0J/Soj system of chromosome segregation. B [...]
 
 
 0.846
murC
UDP-N-acetyl muramate-alanine ligase; Cell wall formation; Belongs to the MurCDEF family.
 
 
 0.843
ftsW
Cell-division protein; Peptidoglycan polymerase that is essential for cell division.
 
 
 0.822
ezrA
Negative regulator of FtsZ ring formation; Negative regulator of FtsZ ring formation; modulates the frequency and position of FtsZ ring formation. Inhibits FtsZ ring formation at polar sites. Interacts either with FtsZ or with one of its binding partners to promote depolymerization.
  
  
 0.806
gpsB
Cell division 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; Belongs to the GpsB family.
 
  
 0.800
yerH
Putative lipoprotein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; lipoprotein.
