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

Score
pbpGSporulation specific penicillin-binding protein; Involved in the polymerization and cross-linking of spore peptidoglycan. May be required for synthesis of the spore germ cell wall, the first layer of peptidoglycan synthesized on the surface of the inner forespore membrane; In the C-terminal section; belongs to the transpeptidase family. (691 aa)    
Predicted Functional Partners:
spoVD
Penicillin-binding protein; Penicillin-binding protein with an unknown catalytic activity. May have a specialized role in the morphogenesis of spore cortex, which is a modified form of peptidoglycan. Pore cortex formation is determined primarily by the mother cell.
 
 
 0.909
spoVE
Factor for spore cortex peptidoglycan synthesis (stage V sporulation); May play an essential role not only during sporulation, but also during vegetative growth; Belongs to the SEDS family. SpoVE subfamily.
  
 
 
 0.854
pbpI
Penicillin-binding protein PBP4B; Penicillin-binding protein with an unknown catalytic activity. Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. 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.
 
 
 0.815
cwlC
N-acetylmuramoyl-L-alanine amidase; Autolysins are involved in some important biological processes such as cell separation, cell-wall turnover, competence for genetic transformation, formation of the flagella - in particular of its basal body - and sporulation. CwlC is able to hydrolyze type A cell walls such as B.subtilis. Its main function is to lyze the mother cell wall peptidoglycan, playing a role during sporulation. Belongs to the N-acetylmuramoyl-L-alanine amidase 3 family.
 
 
 0.814
spoIIQ
Forespore protein required for alternative engulfment; Involved in forespore engulfment and required for anchoring membrane proteins on the forespore side of the septal membrane. Forms a channel with SpoIIIAH that is open on the forespore end and closed (or gated) on the mother cell end. This allows sigma-E-directed gene expression in the mother-cell compartment of the sporangium to trigger the activation of sigma-G forespore-specific gene expression by a pathway of intercellular signaling.
  
  
 0.791
ftsW
Cell-division protein; Peptidoglycan polymerase that is essential for cell division.
  
 
 
 0.745
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.
 
 
 
 0.722
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.
  
 
 
 0.707
rsfA
Prespore-specific regulatory gene; Seems to improve the efficiency of sporulation by fine-tuning the expression of genes in the sigma F regulon, particularly the timing of their expression. Negatively regulates spoIIR and its own synthesis.
  
    0.671
mraY
phospho-N-acetylmuramoyl-pentapeptide transferase; First step of the lipid cycle reactions in the biosynthesis of the cell wall peptidoglycan; Belongs to the glycosyltransferase 4 family. MraY subfamily.
