lyase

ly·ase

L0301900 (lī′ās′)n. 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.]

lyase

(ˈlaɪeɪz) n (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]

Translations

lyase

[li´ās] any of a class of enzymes that remove groups from their substrates (other than by hydrolysis), leaving double bonds, or that conversely add groups to double bonds.

ly·ase

(lī'ās), Class name for those enzymes removing groups nonhydrolytically (EC class 4); prefixes such as "hydro-" and "ammonia-" are used to indicate the type of reaction. Trivial names for lyases include synthases, decarboxylases, aldolases, and dehydratases. Compare: synthase, synthetase.
