1953 Adv. 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.
1961 Rep. Comm. Enzymes Internat. Union Biochem. vi. 34 The name ‘dehydrase’, which has been used for both dehydrogenating and dehydrating enzymes, will not be used. ‘Dehydrogenase’ will be used for the former and ‘dehydratase’ for the latter.
1966 Proc. National Acad. Sci. U.S.A. 55 869 Deamination of homoserine to a-ketobutyrate by homoserine dehydratase is the primary reaction in the catabolism of homoserine.
