Enzymes are biological catalysts; that is, they are biomolecules that accelerate chemical reactions. Most enzymes are proteins -- polymers of amino acid residues -- but a very important small set of enzymes are actually RNA molecules. These RNA enzymes are called ribozymes. Although the Registry at present contains no ribozymes, that's likely to change since ribozymes have the important feature that they can be formed directly from DNA merely by transcription. and do not require translation into protein before they can exert their catalytic effects. That feature will surely soon be exploited by synthetic biologists. (Note that when ribozymes are included in the Registry, they will be classified under "RNA" parts.]
All of the enzyme coding regions in the Registry consist of single polypeptide chains that can fold into catalytically active molecules. Many enzymes are more complicated than this, consisting of two or more subunits that associate with one another to form the active protein. Within the set of available enzyme coding regions there are a number of tables that group the proteins into categories, e.g., antibiotic resistance, DNA excision and integration, etc. These groupings allow easy comparisons among different
