3-hydroxybutyrate dehydrogenase
The enzymic determination of D-3-hydroxybutyrate and acetoacetate normally involves the use of 3hydroxybutyrate dehydrogenase (HBDH, EC 1.1.1.30) of bacterial origin. We show that HBDH from Rhodopseudomonas spheroides (BCL, grade II) contains a 3-hydroxyisobutyrate dehydrogenase (HIBDH) activity: activity with 3-hydroxyisobutyrate as substrate was > 10% of that with 3-hydroxybutyrate. However, ...

متن کاملExtrasynaptic site of action for γ-hydroxybutyrate.
A dvances in pharmacology often result from identifying the mechanism of action of drugs found empirically to be biologically active (1). γ-Hydroxybutyric acid (GHB), also known as Fantasy, is a centrally active agent that has been used clinically and recreationally for nearly half a century. Because of its history of abuse, its availability is tightly regulated, although it is prescribed for t...
متن کاملγ-Hydroxybutyrate (GHB) - Effects on Human Performance and Behavior.
γ-Hydroxybutyrate (GHB) is a powerful central nervous system (CNS) depressant which has had a history of limited therapeutic use and, more recently, potential for abuse. GHB is a naturally occurring compound present in mammalian CNS and peripheral tissues, and a minor metabolite and precursor of γ-amino butyric acid. GHB is also an emerging recreational drug and has limited therapeutic potentia...
متن کاملMetabolism of γ-hydroxybutyrate in perfused rat livers.
GHB (γ-hydroxybutyrate) is both a neurotransmitter and a drug of abuse (date-rape drug). We investigated the catabolism of this compound in perfused rat livers. Using a combination of metabolomics and mass isotopomer analysis, we showed that GHB is metabolized by multiple processes, in addition to its previously reported metabolism in the citric acid cycle via oxidation to succinate. A substrat...
