Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb. Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is ...
The first version was published in 1961, and the Enzyme Commission was dissolved at that time, though its name lives on in the term EC Number. The current sixth edition, published by the International Union of Biochemistry and Molecular Biology in 1992 as the last version published as a printed book, contains 3196 different enzymes. Supplements ...
Enzymes can be classified by two main criteria: either amino acid sequence similarity (and thus evolutionary relationship) or enzymatic activity. Enzyme activity. An enzyme's name is often derived from its substrate or the chemical reaction it catalyzes, with the word ending in -ase.
This list contains a list of sub-classes for the seventh group of Enzyme Commission numbers, EC 7, translocases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology. All official information is tabulated at the website of the committee. [1]
The enzyme classification and nomenclature list was first approved by the International Union of Biochemistry in 1961. Six enzyme classes had been recognized based on the type of chemical reaction catalyzed, including oxidoreductases (EC 1), transferases (EC 2), hydrolases (EC 3), lyases (EC 4), isomerases (EC 5) and ligases (EC 6).
The systematic name of this enzyme class is 2-deoxy-D-ribose-5-phosphate acetaldehyde-lyase (D-glyceraldehyde-3-phosphate-forming). Other names in common use include phosphodeoxyriboaldolase , deoxyriboaldolase , deoxyribose-5-phosphate aldolase , 2-deoxyribose-5-phosphate aldolase , and 2-deoxy-D-ribose-5-phosphate acetaldehyde-lyase .
Ribbon diagram of a protease (TEV protease) complexed with its peptide substrate in black with catalytic residues in red.(. A protease (also called a peptidase, proteinase, or proteolytic enzyme) [1] is an enzyme that catalyzes proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products.

Hydrolases are classified as EC 3 in the EC number classification of enzymes. Hydrolases can be further classified into several subclasses, based upon the bonds they act upon: EC 3.1: ester bonds (esterases: nucleases, phosphodiesterases, lipase, phosphatase) EC 3.2: sugars (DNA glycosylases, glycoside hydrolase)
