Lyase - Wikipedia
In biochemistry, a lyase is an enzyme that catalyzes the breaking (an elimination reaction) of various chemical bonds by means other than hydrolysis (a substitution reaction) and oxidation, often forming a new double bond or a new ring structure. [1] The reverse reaction is also possible (called a Michael reaction).
Lyase - an overview | ScienceDirect Topics
Lyases are enzymes that catalyze the cleavage of chemical bonds (C―C, C―O, C―N and others) by other means than hydrolysis and oxidation (NC-IUBMB). Furthermore, they are capable of forming multiple bonds or new ring structures. Lyases are divided into 7 classes according to the bond broken.
lyase - Encyclopedia Britannica
lyase, in physiology, any member of a class of enzymes that catalyze the addition or removal of the elements of water (hydrogen, oxygen), ammonia (nitrogen, hydrogen), or carbon dioxide (carbon, oxygen) at double bonds. For example, decarboxylases remove carbon dioxide from amino acids and dehydrases remove water. See enzyme.
Lyase - an overview | ScienceDirect Topics
Lyases are the enzymes responsible for catalyzing addition and elimination reactions. Lyase-catalyzed reactions break the bond between a carbon atom and another atom such as oxygen, sulfur, or another carbon atom.

Lyases are enzymes that catalyze the cleavage of C-C, C-O, C-N bonds by other means than by hydrolysis or oxidation. These bonds are cleaved by the process of elimination and the resulting product is the formation of a double bond or a new ring. This class of enzymes differs from other enzymes in that two substrates are involved in one reaction ...

Hydroxynitrile Lyases: Insights into Biochemistry, Discovery, and ...
2011年8月1日 · Hydroxynitrile lyases are valuable enzymes for asymmetric synthesis of cyanohydrins. These hydroxyl and nitrile–containing compounds are being used in production of very useful pharmaceuticals, agrochemicals, and other biologically active compounds using chemical or chemoenzymatic follow-up reactions in industry.
Selenocysteine β-Lyase: Biochemistry, Regulation and …
2019年9月1日 · The enzyme selenocysteine β-lyase (SCLY) was first isolated in 1982 from pig livers, followed by its identification in bacteria. SCLY works as a homodimer, utilizing pyridoxal 5’-phosphate as a cofactor, and catalyzing the specific decomposition of the amino acid selenocysteine into alanine and selenide.
