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.

A Role of a Newly Identified Isomerase From Yarrowia lipolytica in Erythritol Catabolism
Frontiers in Microbiology, 2018 Erythritol is a natural sweetener produced by microorganisms as an osmoprotectant. It belongs to the group of polyols and it can be utilized by the oleaginous yeast Yarrowia lipolytica.

Diversity oriented biosynthesis via accelerated evolution of modular gene clusters
Nature Communications, 2017 Reengineering polyketide synthase encoding genes to produce analogues of natural products can be slow and low-yielding. Here the authors use accelerated evolution to recombine the gene cluster for rapid production of rapamycin-related products.

Observing classical nucleation theory at work by monitoring phase transitions with molecular precision. [PDF]
, 2014 It is widely accepted that many phase transitions do not follow nucleation pathways as envisaged by the classical nucleation theory. Many substances can traverse intermediate states before arriving at the stable phase. The apparent ubiquity of multi-step

Structural and Functional Insights into Human Nuclear Cyclophilins
Biomolecules, 2018 The peptidyl prolyl isomerases (PPI) of the cyclophilin type are distributed throughout human cells, including eight found solely in the nucleus. Nuclear cyclophilins are involved in complexes that regulate chromatin modification, transcription, and pre ...
