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.

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 acts on it

  1. GSSA supplementation supported growth of GSH1-deficient yeast on otherwise glutathione-unsupplemented medium.

    **GSSA recycling and NADPH.** Purified yeast glutathione reductase reduced GSSA with NADPH consumption. Reported apparent Km values were 0.50 mM for GSSA and 0.07 mM for GSSG. They do not establish an eightfold difference in catalytic efficiency: turnover and assay differences matter, and the GSSA measurement deliberately omitted the DTNB cycling reagent used for GSSG. GSSA also supported growth of glutathione-synthesis-defective yeast. That rescue is consistent with recovery of usable glutathione, but it is not a human GSR experiment or proof that this enzyme was the exclusive route in living cells.
