Engineering the Enantioselectivity of Yeast Old Yellow Enzyme OYE2y in Asymmetric Reduction of (E/Z)-Citral to (R)-Citronellal [PDF]

open access: goldMolecules, 2019
The members of the Old Yellow Enzyme (OYE) family are capable of catalyzing the asymmetric reduction of (E/Z)-citral to (R)-citronellal—a key intermediate in the synthesis of L-menthol. The applications of OYE-mediated biotransformation are usually

A Comparative Study of C2-Symmetric and C1-Symmetric Hydroxamic Acids in Vanadium-Catalyzed Asymmetric Epoxidation of Allylic Alcohols [PDF]

open access: yesMolecules
Hydroxamic acids are emerging as versatile chiral ligands for metal-catalyzed asymmetric oxidations due to their tunable electronic and steric environments.

Rational design of enzyme activity and enantioselectivity

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
The strategy of rational design to engineer enzymes is to predict the potential mutants based on the understanding of the relationships between protein structure and function, and subsequently introduce the mutations using the site-directed mutagenesis ...

Enantioselectivity in Drug Pharmacokinetics and Toxicity: Pharmacological Relevance and Analytical Methods

open access: yesMolecules, 2021
Enzymes, receptors, and other binding molecules in biological processes can recognize enantiomers as different molecular entities, due to their different dissociation constants, leading to diverse responses in biological processes. Enantioselectivity can

Enantioselective protonation [PDF]

open access: yesNature Chemistry, 2009
Enantioselective protonation is a common process in biosynthetic sequences. The decarboxylase and esterase enzymes that effect this valuable transformation are able to control both the steric environment around the proton acceptor (typically an enolate) and the proton donor (typically a thiol).

Comprehensive Analysis of a Yeast Lipase Family in the Yarrowia Clade. [PDF]

open access: yesPLoS ONE, 2015
Lipases are currently the subject of intensive studies due to their large range of industrial applications. The Lip2p lipase from the yeast Yarrowia lipolytica (YlLIP2) was recently shown to be a good candidate for different biotechnological applications.

Directed evolution of lipase A from Bacillus subtilis for the preparation of enantiocomplementary sec-alcohols

open access: yesGreen Synthesis and Catalysis, 2021
Biocatalysts with tailor-made or controllable stereoselectivity are valuable and highly desired in the precision synthesis of chiral compounds. Most lipases display excellent (R)-enantioselectivity for various sec-alcohols.

Enantioselective Tsuji Allylations [PDF]

open access: yesChemistry – An Asian Journal, 2007
AbstractThe family of allylation reactions developed by Tsuji in the 1980s are capable of generating tertiary and quaternary carbon stereocenters from several synthetic precursors. Despite the utility of these transformations, they have seen little use in the synthesis of natural products.

Enantioselectivity of discretized helical supramolecule consisting of achiral cobalt phthalocyanines via chiral-induced spin selectivity effect

open access: yesNature Communications, 2023
Enantioselectivity of helical aggregation is conventionally directed either by its homochiral ingredients or by introduction of chiral catalysis. The fundamental question, then, is whether helical aggregation that consists only of achiral components can ...
