dehydrase Biochem.|diːˈhaɪdreɪz, -s|
[a. G. dehydrase (H. Wieland 1913, in Ber. d. Deutsch. Chem. Ges. XLVI. 3333), f. de- II. 3 + hydr- + -ase.]
a. = dehydrogenase.
1914Chem. Abstr. VIII. 3051 It is shown by means of a typical dehydrase, Schardinger's milk enzyme, that oxidase, reductase and mutase are 1 and the same enzyme. 1939Thorpe's Dict. Appl. Chem. (ed. 4) III. 553/2 Citric acid dehydrase is present in the liver and in vegetable material acting on citric acid. 1959N. Campbell in E. H. Rodd Chem. Carbon Compounds IVb. viii. 942 Freudenberg also postulates a second process whereby catechins in the presence of dehydrases undergo condensation by dehydrogenation. 1961[see dehydratase].
b. = dehydratase.
1953Adv. Enzymol. XIV. 243 The usual English term ‘dehydrase’ for an enzyme dehydrating a substrate was changed to dehydratase, because Dehydrase in German..means a dehydrogenating enzyme rather than an enzyme splitting off water. 1957Jrnl. Gen. Microbiol. XVI. 480 The enzymic dehydration of tartaric acid to oxaloacetic acid, first established..for the d-isomer, occurs also with the meso- and l-isomers, and the attack on all three tartaric acids by bacteria of the genus Pseudomonas appears to occur principally by means of stereospecific dehydrases. 1961[see dehydratase]. |
