Function

Toxic component of a type II toxin-antitoxin (TA) system. Phosphorylates UDP-N-acetyl-D-glucosamine (UNAG) on the 3'-hydroxyl group of the N-acetyl-D-glucosamine moiety, yielding UNAG-3P. UNAG-3P inhibits MurA, the first committed step in cell wall synthesis, which is then blocked. Phosphorylation is inhibited by cognate epsilon antitoxin. Part of a postsegregational killing (PSK) system involved in the killing of plasmid-free cells. The zeta toxin induces programmed cell death (By similarity).

Activity summary

Toxin zeta also known as PezT is a bacterial protein with a molecular mass around 31 kDa. It acts as a toxin with functions inside bacterial cells especially in pathogens. This protein modifies cellular molecules by phosphorylating glutamate which affects the cell's metabolism. Toxin zeta usually gets expressed in bacteria as a part of a toxin-antitoxin system where it pairs with an antitoxin called epsilon. Many pathogenic bacteria including some strains of E. coli and Staphylococcus express this protein.

Biological function summary

Toxin zeta functions by impacting bacterial cell division and growth causing reversible dormancy in cells. Toxin zeta becomes part of a toxin-antitoxin (TA) complex where it interacts closely with the antitoxin component to regulate toxic effects. This complex helps bacterial populations survive under stress like when antibiotics are present. By inhibiting peptidoglycan synthesis toxin zeta can restrain bacterial proliferation and induce a dormant state that offers survival benefits under adverse conditions.

Pathways

The activities of toxin zeta fit prominently into bacterial stress response and survival mechanisms. It plays a role in pathways regulating cell growth arrest and programmed cell death. Toxin zeta influences these pathways through its interaction with the antitoxin and regulatory proteins like Lon protease which degrades the antitoxin and frees toxin zeta to exert its effects. Another related protein in these pathways is the MazF toxin which also contributes to bacterial stress responses through similar modes of action.

Associated diseases and disorders

Toxin zeta is connected to chronic and persistent infections particularly those involving antibiotic-resistant bacteria. Its ability to induce dormancy complicates treatment efforts by allowing bacterial cells to evade antibiotic action. Furthermore in persistent infections caused by Staphylococcus aureus toxin zeta may alter treatment outcomes by its interaction with proteins like ClpP which also plays a role in bacterial stress responses. Understanding toxin zeta's functions is important for developing new antibacterial strategies and addressing antibiotic resistance issues in clinical settings.
