Cre01.g043000.t1.1 Radical SAM superfamily protein

Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms.
