7.2.1.3 Three-Tier ClassificationThe Enzyme Commission assigned each enzyme three designations: a systematic name, a trivial name, and an EnzymeCommission (EC) number. Generally, the systematic name is composed of two principal parts. The first consists of the name(s)of the substrate(s); in the case of two or more substrates (or reactants), the name of the substrates are separated by a colon.The second part of the systematic name, ending in -ase, is based on one of the six types of chemical reactions catalyzed (seeSec. 7.2.1.1). When the overall reaction involves two different chemical reactions, such as oxidative demethylation, the secondtype of reaction is listed in parenthesis following the first chemical reaction—for example, “sarcosine:oxygen oxidoreductase(demethylating).”The trivial name is one that is generally recognized and in common use such asa-amylase, cellulase, trypsin, chymotrypsin,peroxidase, or catalase. It is usually a shorter name than the systematic name.The number system derives directly from the classification scheme, and each number contains four digits, separated by periodsand preceded by EC. The numbers are permanent. Newly discovered enzymes are placed at the end of the list underappropriate headings. If the classification of an enzyme is changed, the number remains in the listing, but the user is directed tothe new listing, including the new number of the enzyme.7.2.1.4 Six Main Types of EnzymesThe six main types of enzymes, based on the chemical reaction catalyzed, are further explained in this section.OxidoreductasesOxidoreductases are enzymes that oxidize or reduce substrates by transfer of hydrogens or electrons or by use of oxygen. Thesystematic name is formed as “donor:acceptor oxidoreductase.” An example, including systematic name followed by trivial nameand EC number in parenthesis, is [35]
