The best-known role of proteins in the cell is as [[enzyme]]s, which [[catalysis|catalyse]] chemical reactions. Enzymes are usually highly specific and accelerate only one or a few chemical reactions. Enzymes carry out most of the reactions involved in [[metabolism]], as well as manipulating DNA in processes such as [[DNA replication]], [[DNA repair]], and [[transcription (genetics)|transcription]]. Some enzymes act on other proteins to add or remove chemical groups in a process known as posttranslational modification. About 4,000 reactions are known to be catalysed by enzymes. The rate acceleration conferred by enzymatic catalysis is often enormous—as much as 10<sup>17</sup>-fold increase in rate over the uncatalysed reaction in the case of [[orotate decarboxylase]] (78 million years without the enzyme, 18 milliseconds with the enzyme).</div>FuzzyBot
