Polyol dehydrogenases. 2. The polyol dehydrogenases of Acetobacter suboxydans and Candida utilis*

Sorbitol dehydrogenases in Acetobacter suboxydans.

It has previously been shown that cell-free extracts of Acetobacter subozydans possess two pathways for the oxidation of sorbitol (1). In the presence of DPN,l fructose is produced; with TPN, sorbose is formed. The primary purpose of this paper is to describe the separation of these two dehydrogenases from each other. The DPN enzyme free from TPN activity has been concentrated about lBfold, whe...

Polyol Dehydrogenases of Gluconobacter Oxydans.

The secondary hydroxyl group involved in the oxidation, and the cis-vicinal secondary hydroxyl group, must have a D configuration jvith respect to t,he primary alcohol group adjacent to the site of oxidation. This specific mode of otida,tion facilitated the synthesis of several new ketoses. In a series of papers, Hudson and Richtmyer and their a.ssociates described the microbiological synthesis...

Mannitol oxidase and polyol dehydrogenases in the digestive gland of gastropods: Correlations with phylogeny and diet

Mannitol oxidase and polyol dehydrogenases are enzymes that convert polyalcohols into sugars. Mannitol oxidase was previously investigated in terrestrial snails and slugs, being also present in a few aquatic gastropods. However, the overall distribution of this enzyme in the Gastropoda was not known. Polyol dehydrogenases are also poorly studied in gastropods and other mollusks. In this study, ...
