The Journal of General Physiology, 1956 Rhodopsin is formed by the condensation of opsin with a cis isomer of retinene, called neo-b. The bleaching of rhodopsin releases all-trans retinene which must be isomerized back to neo-b in order for rhodopsin to regenerate. Both retinene isomers are in equilibrium with the corresponding isomers of vitamin A, through the alcohol dehydrogenase system.

Studies on Glucose Isomerase of Bacteria
Agricultural and Biological Chemistry, 1964 A bacterial strain, HN-56, having an activity of d-glucose isomerization was isolated from soil, and was identified to be similar to Aerobacter aerogenes (Kruse) Beijerink. d-Glucose-isomerizing activity was induced when HN-56 was precultured in the media containing d-xylose, d-mannose, lactate, especially d-mannitol.

Vascular thiol isomerases [PDF]
Blood, 2016 AbstractThiol isomerases are multifunctional enzymes that influence protein structure via their oxidoreductase, isomerase, and chaperone activities. These enzymes localize at high concentrations in the endoplasmic reticulum of all eukaryotic cells where they serve an essential function in folding nascent proteins.

Glutathione Transferases as Efficient Ketosteroid Isomerases
Frontiers in Molecular Biosciences, 2021 In addition to their well-established role in detoxication, glutathione transferases (GSTs) have other biological functions. We are focusing on the ketosteroid isomerase activity, which appears to contribute to steroid hormone biosynthesis in mammalian ...

Biotechnology for Biofuels, 2008 Background Ethanolic fermentation of lignocellulosic biomass is a sustainable option for the production of bioethanol. This process would greatly benefit from recombinant Saccharomyces cerevisiae strains also able to ferment, besides the hexose sugar ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression
Hepatology, EarlyView., 2022 Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Biotechnology for Biofuels, 2020 Background Efficient bioethanol production from hemicellulose feedstocks by Saccharomyces cerevisiae requires xylose utilization. Whereas S. cerevisiae does not metabolize xylose, engineered strains that express xylose isomerase can metabolize xylose by ...

Protein disulphide isomerase inhibition as a potential cancer therapeutic strategy
Cancer Medicine, 2021 The protein disulphide isomerase (PDI) gene family is a large, diverse group of enzymes recognised for their roles in disulphide bond formation within the endoplasmic reticulum (ER).
