UniProtKB - P54373 (TXPA_BACSU)
Protein
Toxin TxpA
Gene
txpA
Organism
Bacillus subtilis (strain 168)
Status
Functioni
Toxic component of a type I toxin-antitoxin (TA) system (PubMed:16166525). Overexpression of txpA causes cell lysis; the TxpA protein has been suggested to act on the cell membrane or might possibly block cell wall synthesis (PubMed:16166525). Overexpression in E.coli is not toxic (PubMed:16166525).1 Publication1 Publication
Miscellaneous
Encoded in a 48-kb, phage-like element known as skin.1 Publication

Expressioni
Inductioni
The antisense RNA ratA acts as an antitoxin by annealing to the mRNA of txpA and causing its degradation, protecting the cell from TxpA by blocking the production of the toxin. A type I toxin-antitoxin (TA) system, where expression of the proteinaceous toxin is controlled by an antisense sRNA.1 Publication
