Definition Cofactor is a nonprotein (organic or inorganic) factor necessary for the activity of an enzyme . This factor can be firmly bound to the enzyme (i.e., prosthetic group, e.g., cytochromes ) or freely dissociable (i.e., coenzyme , e.g., NAD(P)H). See Also Coenzyme ...
A cofactor is a molecule that is a part of the active site of an enzyme and is regenerated with each turnover of substrate. It can be dissociated from the enzyme and an example of a cofactor is pyridoxal phosphate, which is involved in various group-transferring enzymes. ...
