<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 <a href="http://www.uniprot.org/help/function_section">Function</a> 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 <a href="http://www.uniprot.org/help/names_and_taxonomy_section">Names and taxonomy</a> 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
