Lyase - Wikipedia
WebIn 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.
Lyase | Britannica
Weblyase, 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 Definition and Examples - Biology Online Dictionary
WebJul 1, 2021 · Lyases are enzymes that catalyze the breaking a chemical bond between two parts of a molecule through biochemical means other than hydrolysis and oxidation. They often form a double bond or add a new ring structure. An example is the lyase that acts on ATP resulting in the formation of cAMP and PP i.
Lyase Definition & Meaning - Merriam-Webster
WebThe meaning of LYASE is an enzyme (such as a decarboxylase) that forms double bonds by removing groups from a substrate other than by hydrolysis or that adds groups to double bonds.
Lyase Introduction - Creative Enzymes
WebLyase Introduction. In physiology, lyase is an enzyme catalytically aiding in breaking various chemical bonds by means of an "elimination" reaction, other than hydrolysis and oxidation. This reaction often results in the formation of a new cyclic structure or a new double bond, and a reverse reaction called a "Michael addition" might also ...

WebLyase enzymes are also known as transeliminases, which break down pectate or pectinate polymers using a transeliminative mechanism. Typically, lyases break the glycosidic linkages at the fourth carbon and then remove a hydrogen atom from the fifth carbon to form unsaturated products.

WebJun 9, 2023 · Overview. 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 …
