| dehydratase | A subclass (EC 4.2.1) of lyases (hydro-lyases) that remove H and OH as H2O from a substrate, leaving a double bond, or add a group to a double bond by the elimination of water from two substances to form a third; synthase is sometimes used when the synthetic aspect of the reaction is emphasized. Some trivial names of enzymes in this subclass bear the generic term hydratase, emphasizing the reverse reaction. (05 Mar 2000) |

| bile acid 7alpha-dehydratase | <enzyme> Enzyme in the bacterial bile acid 7alpha-dehydroxylation pathway Registry number: EC 4.2.1.- Synonym: c24 bile acid 7alpha-dehydratase, ba7alphad, baie gene product (26 Jun 1999) |
|---|---|
| carbonate dehydratase | <enzyme> A zinc-containing enzyme of erythrocytes with molecular weight of 30 kD. It is among the most active of known enzymes and catalyses the reversible hydration of carbon dioxide, which is significant in the transport of co2 from the tissues to the lungs. The enzyme is inhibited by acetazolamide. Chemical name: Carbonate hydro-lyase Registry number: EC 4.2.1.1 (12 Dec 1998) |
| carbonate dehydratase inhibitor | An agent, usually chemically related to the sulfonamides, that inhibits the activity of carbonate dehydratase, producing a general decrease in the formation of H2CO3 in the tissues. See: acetazolamide, dichlorphenamide. Synonym: carbonic anhydrase inhibitor. (05 Mar 2000) |
| carnitine dehydratase | <enzyme> From E coli; catalyses the reversible dehydration of (l)-carnitine forming crotonobetaine Registry number: EC 4.2.1.- Synonym: caib protein, caib gene product (26 Jun 1999) |
| galactonate dehydratase | <enzyme> In mutant of klebsiella pneumoniae also functions in catabolism of d-fuconate Registry number: EC 4.2.1.6 Synonym: galactonate dehydrase, d-galactonate dehydratase, d-galactonate-d-fuconate dehydratase (26 Jun 1999) |
| glycerol dehydratase | <enzyme> Requires a cobamide coenzyme Registry number: EC 4.2.1.30 (26 Jun 1999) |

| cyclohexadienyl dehydratase | <enzyme> From pseudomonas aeruginosa; catalyses both prephenate dehydratase and arogenate dehydratase reactions Registry number: EC 4.2.1.- (26 Jun 1999) |
| prephenate dehydratase | <enzyme> An enzyme that catalyses the conversion of prephenate to phenylpyruvate with the elimination of water and carbon dioxide. In the enteric bacteria this enzyme also possesses chorismate mutase activity, thereby catalyzing the first two steps in the biosynthesis of phenylalanine. Chemical name: Prephenate hydro-lyase (decarboxylating) Registry number: EC 4.2.1.51 (12 Dec 1998) |

| scytalone dehydratase | <enzyme> Converts scytalone to 1,3,8-trihydroxynapthalene; on path to melanin biosynthesis Registry number: EC 4.2.1.94 (26 Jun 1999) |
| pterin-4a-carbinolamine dehydratase | <enzyme> Bifunctional protein which converts pterin-4a-carbinolamine to quinoid dihydrobiopterin and functions as dimerization cofactor for hnf-1alpha; deficiency results in an atypical form of phenylketonuria; proposed EC 4.2.1.96 Registry number: EC 4.2.1.- Synonym: pt-c dehydratase, phenylalanine hydroxylase-stimulating protein, pterin-4alpha-carbinolamine dehydratase, dcoh protein, dimerization cofactor of hnf-1alpha, 4a-hydroxytetrahydrobiopterin dehydratase, 4a-carbinolamine dehydratase, bh3oh dehydratase, 4alpha-carbinolamine dehydratase (26 Jun 1999) |
| homoserine dehydratase | <enzyme> A multifunctional pyridoxal phosphate enzyme. In the final step in the biosynthesis of cysteine it catalyses the cleavage of cystathionine to yield cysteine, ammonia, and 2-ketobutyrate. Chemical name: L-Cystathionine cysteine-lyase (deaminating) Registry number: EC 4.4.1.1 (12 Dec 1998) |
| pyranosone dehydratase | <enzyme> From phanerochaete chrysosporium; acts on several osones (glycosuloses) with the preferred substrate being d-glucosone which was converted by the enzyme to cortalcerone; the pyranose form of glucosone undergoes two enzymatic dehydrations to give cortalcerone on spontaneous cyclization Registry number: EC 4.2.1.- Synonym: aldos-2-ulose dehydratase (26 Jun 1999) |
| dehydratase |
a term used in the usual recommended or trivial name for enzymes of the sub-subclass hydro-lyase (q.v.).
