Target Background

Function
Antitoxin component of a type II toxin-antitoxin (TA) system. Labile antitoxin that binds to the MazF endoribonuclease toxin and neutralizes its endoribonuclease activity. Is considered to be an 'addiction' molecule as the cell dies in its absence. Toxicity results when the levels of MazE decrease in the cell, leading to mRNA degradation. This effect can be rescued by expression of MazE, but after 6 hours in rich medium the overexpression of MazF leads to programmed cell death. Cell growth and viability are not affected when MazF and MazE are coexpressed. Both MazE and MazE-MazF bind to the promoter region of the mazE-mazF operon to inhibit their own transcription. There are 3 operators to which MazE binds. MazE has higher affinity for promoter DNA in the presence of MazF.; Cell death governed by the MazE-MazF and DinJ-YafQ TA systems seems to play a role in biofilm formation, while MazE-MazF is also implicated in cell death in liquid media.; Might also serve to protect cells against bacteriophage; in the presence of MazE-MazF fewer P1 phage are produced than in a disrupted strain. For strain K38 most wild-type cells are killed but not by phage lysis; it was suggested that MazE-MazF causes P1 phage exclusion from the bacterial population. This phenomenon is strain dependent.

  2. The MazE C-terminus plays an important role in the MazF binding, which was found to increase the MazE affinity for the palindromic single site operator. PMID: 25564525
  3. The mazE and mazF-mediated cell death pathway prevents the effect of DNA damage on membrane depolarization in E. coli. PMID: 22412352
  4. effect of mazEF on the development of bacteriophage P1 PMID: 15316771
  5. results reported here support the view that the mazEF module mediates cell death and is part of a programmed cell death network PMID: 15576778
  6. analysis of energetics of structural transitions of the addiction antitoxin MazE PMID: 15735309
  7. study reports that E. coli mazEF-mediated cell death is a population phenomenon requiring a quorum-sensing molecule that we call the extracellular death factor (EDF); structural analysis revealed that EDF is a linear pentapeptide, Asn-Asn-Trp-Asn-Asn PMID: 17962566
  8. our results showed that the mode of action of antibiotics was determined by the ability of E. coli cells to communicate through the signaling molecule Extracellular Death Factor (EDF) participating in mazEF induction. PMID: 19090622
