<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functionⁱ

<p>This subsection of the ‘Function’ section describes the catalytic activity of an enzyme, i.e. the chemical reaction it catalyzes. This information usually correlates with the presence of an EC (Enzyme Commission) number in the ‘Names and taxonomy’ section.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityⁱ

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactorⁱ
