Three Adh genes were identified in Hordeum vulgare and H. spontaneum (114, 338, 341, 361). Two of these were tightly linked at the Adh-H1 locus (114). The third gene was tentatively located in 5H (338).
The gene series formerly designated Adh-2 and Adh-3 now appear in the section entitled 'Alcohol dehydrogenase (aromatic)'.
A low-level of aliphatic alcohol dehydrogenase activity is commonly observed on zymograms in the absence of added substrate (359); this may account for the observation of wheat lactate dehydrogenase that was reported in 1063.
