Cofactor (biochemistry) - Wikipedia

WebOther enzymes contain a nonprotein component called a cofactor that is necessary for the enzyme’s proper functioning. There are two types of cofactors: inorganic ions [e.g., zinc or Cu (I) ions] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins. WebA cofactor may be a metal—such as iron, copper, or magnesium —a moderately sized organic molecule called a prosthetic group, or a special type of substrate molecule known as a coenzyme. The cofactor may aid in the catalytic function of an enzyme, as do metals and prosthetic groups, or take part in the enzymatic reaction, as do coenzymes. A ... scottish government budget 2016-17
