(S)-hydroxynitrile Lyase
(''S'')-hydroxynitrile lyase (, ''(S)-cyanohydrin producing hydroxynitrile lyase'', ''(S)-oxynitrilase'', ''(S)-HbHNL'', ''(S)-MeHNL'', ''hydroxynitrile lyase'', ''oxynitrilase'', ''HbHNL'', ''MeHNL'', ''(S)-selective hydroxynitrile lyase'', ''(S)-cyanohydrin carbonyl-lyase (cyanide forming)'', hydroxynitrilase) is an enzyme with List of enzymes, systematic name ''(S)-cyanohydrin lyase (cyanide forming)''. This enzyme catalysis, catalyses the interconversion between cyanohydrins and the carbonyl compounds derived from the cyanohydrin with free cyanide, as in the following two chemical reactions: * an aliphatic (''S'')-hydroxynitrile \rightleftharpoons an aliphatic aldehyde or ketone + cyanide * an aromatic (''S'')-hydroxynitrile \rightleftharpoons an aromatic aldehyde + cyanide In nature, the liberation of cyanide serves as a defense mechanism against herbivores and microbial attack in plants. Hydroxynitrile lyases of the alpha/beta hydrolase fold, α/β hydrolase fold are closely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroxynitrilase
In enzymology, a hydroxynitrilase () is an enzyme that catalysis, catalyzes the chemical reaction :acetone cyanohydrin \rightleftharpoons cyanide + acetone Hence, this enzyme has one substrate (biochemistry), substrate, acetone cyanohydrin, and two product (chemistry), products, cyanide and acetone. This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The List of enzymes, systematic name of this enzyme class is acetone-cyanohydrin acetone-lyase (cyanide-forming). Other names in common use include alpha-hydroxynitrile lyase, hydroxynitrile lyase, acetone-cyanhydrin lyase [mis-spelt], acetone-cyanohydrin acetone-lyase, oxynitrilase, 2-hydroxyisobutyronitrile acetone-lyase, 2-hydroxyisobutyronitrile acetone-lyase (cyanide-forming), and acetone-cyanohydrin lyase.
