Related to Lyases: Isomerases, Transferases


Any of a class of enzymes that catalyze the cleavage of bonds without hydrolysis or oxidation, often resulting in a new double bond or ring structure, or that catalyze the addition of chemical groups to double bonds.

[Greek lūein, to loosen; see leu- in Indo-European roots + -ase.]


(Biochemistry) any enzyme that catalyses the separation of two parts of a molecule by the formation of a double bond between them
[C20: from Greek lusis a loosening + -ase]

Pectin lyases are significant compared to that of PG and PE in capability to undergo [beta]-elimination mechanism to degrade highly esterified pectins (present in fruits) into small molecules without producing methanol (7).
Bacillus cereus GS-2 isolated from fruit industrial dump site effectively produces pectin lyase (PL) and Polygalacturonase (PG).
Among the depolymerases, polygalacturonase is the major enzyme with a hydrolytic function and lyases (or transeleminases) which cleaves glycosidic bonds forming unsaturated product[DELTA](4,5-D-galacturonate) through transelimination reaction [34].
Pectin lyases are the only known pectinases capable of degrading highly esterified pectins (like those found in fruits) into small molecules via [beta]-elimination mechanism without producing methanol.
The aim of this project is to provide training in the multidisciplinary fields of organic chemistry, bio-catalysis, molecular biology, biochemistry and microbiology to design and develop artificial cascades by combining various types of enzymes such as L-amino acid oxidases, alcohol dehydrogenases and lyases.
He covers chiral discrimination in the active site of oxidoreductases, transferases and chiral discrimination, the influence of chirality on the hydrolysis reactions within the active site of hydrolases, the influence of chirality on the reactions in the active site of lyases, and chiral discrimination in the active site of ligases.
Genomic and functional characterization of the oas gene family encoding O-acetylserine (thiol) lyases, enzymes catalyzing the final step in cysteine biosynthesis in Arabidopsis thaliana.
O-acetylserine (thiol) lyase is a pyridoxal phosphate-dependent enzyme, and a lysine residue at the N-terminal region of this protein is involved in binding this cofactor (Saito et al.
These enzymes are grouped into six classes: hydrolases (including proteases, amylases and lipases that break down the main nutrients - fats, carbohydrates and proteins), isomerases, ligases, lyases, oxidoreductases and transferases.
