The copper, zinc superoxide dismutase active-site copper and Arg141 pocket

The copper, zinc superoxide dismutase active-site copper and Arg141 pocket. Species, exposure and limitations are retained in each linked claim.

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.

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.

Recorded relationships

Where it participates (unsigned role)

  1. Copper, zinc superoxide dismutase catalyses the two-step dismutation of superoxide to molecular oxygen and hydrogen peroxide through alternate reduction and oxidation of the active-site copper, with a single complementary binding position for superoxide at the Cu(II) and the activity-important Arg141.
