Chemoenzymatic catalysis, by definition, involves the merging of sequential reactions using both chemocatalysis and biocatalysis, typically in a single reaction vessel. A major challenge, solution to which, however, is associated with numerous advantages, run such one-pot processes water: majority enzyme-catalyzed take place water as Nature's medium, thus enabling broad synthetic diversity when due option use virtually all types enzymes. Furthermore, cheap, abundantly available, environmentally friendly, making it, principle, an ideal medium. On other hand, most routinely performed today organic solvents (which might deactivate enzymes), appearing make it difficult combine biocatalysis toward cascades water. Several creative approaches solutions that enable combinations chemo- be realized applied problems are presented herein, reflecting state-of-the-art this blossoming field.

Enhancing Enzyme Activity by the Modulation of Covalent Interactions in the Confined Channels of Covalent Organic Frameworks

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(21)

Published: March 10, 2022

Controllable regulations on the enzyme conformation to optimize catalytic performance are highly desired for immobilized biocatalysts yet remain challenging. Covalent organic frameworks (COFs) possess confined channels with finely tunable pore environment, offering a promising platform encapsulation. Herein, we covalently cytochrome c (Cyt c) in size-matched of COFs different contents anchoring site, and significant enhancement stability activity (≈600 % relative compared free enzyme) can be realized by optimizing covalent interactions. Structural analyses Cyt suggest that bonding could induce conformational perturbation resulting more accessible active sites. The effectiveness interaction modulation together tailorable offers promise develop high-performance biocatalysts.

Bioinspired Coassembly of Copper Ions and Nicotinamide Adenine Dinucleotides for Single-Site Nanozyme with Dual Catalytic Functions

Analytical Chemistry, Journal Year: 2023, Volume and Issue: 95(5), P. 2865 - 2873

Published: Jan. 24, 2023

Nanozymes can imitate the catalytic properties of natural enzymes while overcoming limitations such as high cost, poor robustness, and difficulty in recycling. However, rational design facile preparation nanozymes are still demand. Inspired by chemical structure laccase, we report an amorphous metal-organic coordination nanocomposite named CuNAD, which is composed copper ions nicotinamide adenine dinucleotide (NAD+) via a simple coordinating coassembly process. As single-site nanozyme, CuNAD exhibits excellent robustness under extreme conditions, significantly stronger activity for phenolic compounds, 4.02-fold higher sensitivity epinephrine detection than laccase. Furthermore, breaking through functional constraints also able to activate H2O2 at neutral pH, benefiting one-step chromogenic platform cholesterol. This approach demonstrates potential develop biomimicking may boost more insights into structure-function relationship nanozymes.

A review on the immobilization of pepsin: A Lys-poor enzyme that is unstable at alkaline pH values

International Journal of Biological Macromolecules, Journal Year: 2022, Volume and Issue: 210, P. 682 - 702

Published: May 1, 2022

Pepsin is a protease used in many different applications, and instances, it utilized an immobilized form to prevent contamination of the reaction product. This enzyme has two peculiarities that make its immobilization complex. The first one related poor presence primary amino groups on surface (just Lys terminal group). second stability at alkaline pH values. Both features this be considered complicated goal, as most protocols utilize for immobilization. review presents some attempts get pepsin biocatalyst their applications. high density anionic (Asp Glu) anion exchange simpler, but makes strategies immobilize (e.g., amino-glutaraldehyde supports) more mixed ion exchange/hydrophobic adsorption than real covalent Finally, we propose possibilities can permit not only enzyme, also stabilization via multipoint attachment.
