WebFeb 17, 2015 · We recently identified an acetate-based biochemical switch in mammalian cells that differentially regulates recruitment of an acetylase/coactivator, CBP, to a stress-responsive transcription factor, HIF-2, during stress induced by hypoxia . Activation of the acetate switch results in production of a specific pool of acetyl CoA by the acetate ... WebSwitch biochemical In an extensive study, Okamoto and co-workers [76-86] introduced a biochemical switching device based on a cyclic enzyme system in which two enzymes share two cofactors in a cyclic manner. Cyclic enzyme systems have been used as biochemical amplitiers to improve the sensitivity of enzymatic analysis [87-89], and …
