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

pbpIPenicillin-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. (584 aa)    
Predicted Functional Partners:
yrrS
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 14679248.
  
 
 0.985
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.
 
 
 0.818
pbpG
Sporulation 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.
 
 
 0.815
ypbE
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 16855244.
  
 
 0.688
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.
 
 
 0.664
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.
 
  
 0.663
greA
Transcription elongation factor; Necessary for efficient RNA polymerase transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by cleavage factors such as GreA or GreB allows the resumption of elongation from the new 3'terminus. GreA releases sequences of 2 to 3 nucleotides (By similarity); Belongs to the GreA/GreB family.
       0.662
ftsW
Cell-division protein; Peptidoglycan polymerase that is essential for cell division.
 
 
 0.652
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 [...]

ylaJ
Putative lipoprotein; Probably contributes, directly or indirectly, to early events in germination.
