Designing Enzymatic Reactivity with an Expanded Palette

ChemBioChem, EarlyView.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

Exploring the Stability and Substrate Profile of Transaminase from Silicibacter pomeroyi with Ancestral Sequence Reconstruction

ChemBioChem, EarlyView.
This study describes the successful identification of ancestral sequences N50 and N49, which have a longer half‐life of approximately four and two times the wild‐type Sp‐amine transaminase, respectively.. This approach effectively enhances the thermal stability of the transaminase.

Oxidation reactions are required to produce atranorin from acetate by alginate-immobilized cells of Cladonia verticillaris. [PDF]

, 2000
Atranorin, a p-depside of the b-orcinol series, is produced by several Cladonia species. Immobilized cells of Cladonia verticillaris in calcium alginate are able to produce atranorin when they are supplied with 1.0 mM acetate as a precursor.

Comparative transcriptomic analysis unveils interactions between the regulatory CarS protein and light response in Fusarium [PDF]

, 2019
Background The orange pigmentation of the agar cultures of many Fusarium species is due to the production of carotenoids, terpenoid pigments whose synthesis is stimulated by light.

A Biocatalytic Cascade for the Valorization of Sugars

ChemCatChem, EarlyView.
We report a one‐pot, three‐step biocatalytic cascade to synthesize trihydroxy‐piperidine and ‐azepane iminosugars directly from monosaccharides, employing transaminase (ATA) and galactose oxidase (GOase) enzymes. Abstract Biocatalytic cascades offer products of multistep synthesis without the use of protecting groups or isolation of intermediates. This

Polar Microalgae: New Approaches towards Understanding Adaptations to an Extreme and Changing Environment [PDF]

, 2014
Polar Regions are unique and highly prolific ecosystems characterized by extreme environmental gradients. Photosynthetic autotrophs, the base of the food web, have had to adapt physiological mechanisms to maintain growth, reproduction and metabolic ...

Regulation of aldehyde reductase expression by STAF and CHOP

Genomics, 2004
Aldehyde reductase is involved in the reductive detoxification of reactive aldehydes that can modify cellular macromolecules. To analyze the mechanism of basal regulation of aldehyde reductase expression, we cloned the murine gene and adjacent regulatory region and compared it to the human gene.

Synthesis, Antimycobacterial Activity and Computational Insight of novel 1,4‐Benzoxazin‐2‐one Derivatives as Promising Candidates Against Multidrug‐Resistant M. tuberculosis

ChemMedChem, Accepted Article.
To search for new antitubercular agents, we have designed, synthesized, and evaluated a series of 1,4‐benzoxazinone‐based compounds. These molecules showed potent antimycobacterial activity, with MIC between 2 and 8 μg/mL. This interesting profile included activity against several drug‐resistant strains and minimal cytotoxicity against mammalian Vero ...

Biosynthesis of lignans. Part I . Biosynthesis of Arctiin (3) and Phillyrin (5) [PDF]

, 1977
Lignans constitute a class of naturally occuring phenolic compounds, widely distributed in higher plants. They are formally composed of two phenylpropanoid units, stercospecifically joined at the /f-carbon atoms of their side chains. Their biosynthesis

Intracellular and Extracellular Efficacy of Homoisoflavone Derivatives Against Mycobacterium tuberculosis: Progress Toward Novel Antitubercular Agents

ChemMedChem, Accepted Article.
Tuberculosis (TB) is the leading cause of death among infectious diseases, and new studies focusing new anti‐TB drugs are urgent due to the emergence of drug‐resistant strains. In this regard, homoisoflavones, an underexplored subgroup of flavonoids, were explored for their potential as anti‐TB agents.
