How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Allicin shifted the bacillithiol redox potential toward a more oxidized state in Staphylococcus aureus.

- evidence_access
- Primary indexed abstract reviewed; full methods, exact concentrations or species-specific attribution remain unextracted unless explicitly stated in the abstract or separately verified publisher text.
- experimental_contrast
- {"intervention": "Allicin stress", "comparator": "Matched unstressed bacterial cells", "endpoint": "Allicin shifted the bacillithiol redox potential toward a more oxidized state in Staphylococcus aureus.", "effect_direction": "increase", "combination": "single", "conditions": []} Explicit extracted experimental comparison; source-derived draft.
- experimental_model
- Bacterial redox-biosensor study; primary abstract; exact dose/time unextracted.
- interpretation_status
- Source-derived extraction of a fact-checked reference; access is explicit, not independent raw-data verification.
- limitations
- Redox potential is not total bacillithiol depletion; no equivalence to human GSH physiology.

**Bacterial thiol systems differ.** Staphylococcus aureus uses bacillithiol rather than treating glutathione as its universal buffer. The 2019 study reported a bacillithiol redox shift, protein S-thioallylation, and reversal through bacilliredoxin/bacillithiol/YpdA chemistry; YpdA could use the allyl-bacillithiol adduct to regenerate bacillithiol. These are organism-specific repair findings, not evidence for the same proteins in humans. [Loi 2019](https://pubmed.ncbi.nlm.nih.gov/31121222/)
