Component
Metal-free human SOD2
Human SOD2 apoprotein; metal loading required for catalytic reconstitution.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
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 it acts on
At 30 °C, more than half of human SOD2 purified from expressing yeast mitochondria was apoprotein, and that apoprotein could be fully activated by reconstitution.
Experimental context and source evidence
- experimental_model
- Human SOD2 expressed in Saccharomyces cerevisiae and purified from yeast mitochondria
- exposure
- Heterologous expression; metallation and reconstitution
- limitations
- Heterologous yeast expression, not endogenous human tissue. The indexed abstract does not specify a reconstitution dose.
- nutrient_topic
- Manganese research collection; topical membership is not evidence of a direct dietary effect. · Manganese
- organism
- Human protein in Saccharomyces cerevisiae
- plain_language
- Making SOD2 protein does not guarantee that it has loaded its metal.
