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).
[1] [43] This is accomplished by three enzymes referred to as the B, C, and D proteins; the precursor peptide is referred to as the A protein, as in other classes. [1] The C protein is mainly involved in leader peptide recognition and binding and is sometimes called a scaffolding protein. The D protein is an ATP-dependent cyclodehydratase that ...

They prevent misfolding of proteins during stressful situations such as high heat, by assisting protein folding. HSP60 belong to a large class of molecules that assist protein folding, called molecular chaperones. [2] [3] Newly made proteins usually must fold from a linear chain of amino acids into a three-dimensional tertiary structure. The ...
Enzymes (/ ˈ ɛ n z aɪ m z /) are proteins that act as biological catalysts by accelerating chemical reactions.The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Exopeptidases are enzymes that can cleave the end of an amino acid side chain mostly through the addition of water. [6] Exopeptidase enzymes exist in the small intestine. These enzymes have two classes: aminopeptidases are a brush border enzyme and carboxypeptidases which is from the pancreas.
Enzymes appear in the subcategory Category:Enzymes by function according to the EC number classification: . EC 1 Oxidoreductases: catalyze oxidation/reduction reactions; EC 2 Transferases: transfer a functional group (e.g. a methyl or phosphate group)
Adenosine triphosphate Adenosine diphosphate Adenosine monophosphate. ATPases (EC 3.6.1.3, Adenosine 5'-TriPhosphatase, adenylpyrophosphatase, ATP monophosphatase, triphosphatase, SV40 T-antigen, ATP hydrolase, complex V (mitochondrial electron transport), (Ca 2+ + Mg 2+)-ATPase, HCO 3 −-ATPase, adenosine triphosphatase) are a class of enzymes that catalyze the decomposition of ATP into ADP ...
