| D-xylo-aldonate dehydratase | <enzyme> Forms 2-keto-3-deoxy-d-xylonate (d-pentulosonic acid) Registry number: EC 4.2.1.- Synonym: d-xylonate dehydratase (26 Jun 1999) |
| threonine dehydratase | <enzyme> A pyridoxal-phosphate protein that catalyses the deamination of threonine to 2-ketobutyrate and ammonia. The role of this enzyme can be biosynthetic or biodegradative. In the former role it supplies 2-ketobutyrate required for isoleucine biosynthesis, while in the latter it is only involved in the breakdown of threonine to supply energy. Chemical name: L-Threonine hydro-lyase (deaminating) Registry number: EC 4.2.1.16 (12 Dec 1998) |
| 16 alpha-hydroxyprogesterone dehydratase | <enzyme> From rat intestinal anaerobic bacteria; forms 16-dehydroprogesterone Registry number: EC 4.2.1.- Synonym: 16 alpha-dehydratase (26 Jun 1999) |
| lactate dehydratase | <enzyme> From cell extracts of clostridium propionicum; catalyses the dehydration of (r)-lactate to acrylate Registry number: EC 4.2.1.54 Synonym: lactyl CoA dehydratase, lactyl coenzyme a dehydratase, lactoyl-CoA dehydratase (26 Jun 1999) |
| 2-hydroxyglutaryl-CoA dehydratase | <enzyme> From acidaminococcus fermentans; catalyses dehydration of (r)-2-hydroxyglutarate in the presence of acetyl-CoA and glutaconate CoA transferase; forms glutaconyl-CoA, an iron-sulfur enzyme. Registry number: EC 4.2.1.- Synonym: 2-hydroxyglutaryl-coenzyme a dehydratase (26 Jun 1999) |
| 3-dehydroshikimate dehydratase | <enzyme> Third enzyme in neurospora crass quinic acid catabolic pathway Registry number: EC 4.2.1.- Synonym: quic protein, quic gene product (26 Jun 1999) |
| 3-phenylserine dehydratase | <enzyme> Catalyses deamination of l-threo-3-phenylserine to yield phenylpyruvate and ammonia; partial amino acid sequence given in first source Registry number: EC 4.2.1.- Synonym: l-threo-phenylserine dehydratase (26 Jun 1999) |
| 4-hydroxybutyryl-CoA dehydratase | <enzyme> Forms vinylacetyl-CoA from 4-hydroxybutyryl-CoA Registry number: EC 4.2.1.- Synonym: gamma-hydroxybutyryl-CoA dehydratase (26 Jun 1999) |
| 5-hydroxyvaleryl-CoA dehydratase | <enzyme> Contains fad; bifunctional enzyme which catalyses reversible dehydration of 5-hydroxyvaleryl-CoA to 4-pentenoyl-CoA Registry number: EC 4.2.1.- Synonym: 5hvc-dehydratase, 5-hydroxyvaleryl-CoA dehydratase-dehydrogenase (26 Jun 1999) |
| 7,2'-dihydroxy-4'-methoxyisoflavanol dehydratase | <enzyme> Catalyses loss of water and closure of an ether ring to form medicarpin Registry number: EC 4.2.1.- Synonym: 2',7-dihydroxy-4'-methoxyisoflavanol dehydratase, dmi dehydratase (26 Jun 1999) |
