   • 1953, Advances in Enzymology, volume 14, page 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.

     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.

Usage notes

• The polysemic term dehydrase has been superseded by the more specific terms dehydrogenase and dehydratase since its proscription by the IUBMB in 1961.
