found: Dioxygen activation, via Goldberg Group, Johns Hopkins University, website, June 30, 2020(Dioxygen activation is a key step in many of the metabolic and biosynthetic processes that are required for aerobic life. Though dioxygen is a powerful oxidant, its reactivity is spin forbidden and thus kinetically disfavored. However, redox active, 3d transition metals are employed in nature to harness the oxidative potential of O₂ by binding and activating O₂, generating metal-oxygen intermediates that can favorably oxidize biological substrates. The metals employed in the active sites of these O2 activating enzymes span the 3d series and contain a diverse array of ligand sets, often categorized as heme and nonheme. Nonheme iron-containing oxygenases and oxidases represent one of the largest classes of these O₂ activating enzymes)
