“…This could be attributed to enzyme molecules adsorbing onto the pores and surface of the resin, forming new irregular voids, especially within the mesopore range, during the co-immobilization process [ 45 ]. Meanwhile, when the ratio of the two enzymes was 5:1, the smallest pore size of the immobilized enzyme was measured at 7.065 nm, indicating effective adsorption of enzyme molecules at this point [ 46 ].…”

Enzymatically derived selenium-enriched peptides from Cardamine violifolia (CV) can serve as valuable selenium supplements. However, the industrial application of free enzyme is impeded by its limited stability and reusability. Herein, this study explores the application of co-immobilized enzymes (Alcalase and Dispase) on amino resin for hydrolyzing CV proteins to produce selenium-enriched peptides. The successful enzyme immobilization was confirmed through scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and Fourier-transform infrared spectroscopy (FTIR). Co-immobilized enzyme at a mass ratio of 5:1 (Alcalase/Dispase) exhibited the smallest pore size (7.065 nm) and highest activity (41 U/mg), resulting in a high degree of hydrolysis of CV protein (27.2%), which was obviously higher than the case of using free enzymes (20.7%) or immobilized Alcalase (25.8%). In addition, after a month of storage, the co-immobilized enzyme still retained a viability level of 41.93%, showing fairly good stability. Encouragingly, the selenium-enriched peptides from co-immobilized enzyme hydrolysis exhibited uniform distribution of selenium forms, complete amino acid fractions and homogeneous distribution of molecular weight, confirming the practicality of using co-immobilized enzymes for CV protein hydrolysis.

“…Lipase is a family of enzymes that catalyzes the hydrolysis of fats. As efficient and “green” biocatalysts, 1 lipases have been widely used in hydrolysis, 2 alcoholysis, 3 esterification 4 and transesterification reactions, 5 and are considered to be the most valuable enzymes in the biological-production industry. 6 Due to the special structure of lipases, a relatively hydrophobic α-helix “lid” covers the central surface of the catalytic active site and has a protective role.…”

Lipases have drawn significant attention due to their crucial roles across various industries, including oil processing, food, medicine, and daily chemicals. Nevertheless, their catalytic efficiency is susceptible to fluctuations in external environmental conditions, which remains a major barrier to their broader application. In this research, chiral hydrogel microspheres (HMSs) are developed by incorporating L/D‐Co3O4 nanoparticles (NPs) into the synthetic process of HMSs, which are discovered to enhance the catalytic performance of lipases. The improved catalytic activity of lipases is observed to be influenced by the chiral environment of L/D‐Co3O4‐HMSs. Specifically, when 2 wt.% lipases are encapsulated in L‐Co3O4‐HMSs containing 10 wt.% L‐Co3O4 NPs, their catalytic activity is 2.11 times higher than when encapsulated in D‐Co3O4‐HMSs, resulting in a 2.62‐fold increase in catalytic activity compared to free lipase. Moreover, the L‐Lip‐HMS3, which contained 2 wt.% lipases and 10 wt.% L‐Co3O4 NPs, exhibited superior inhibitory capability over D‐Lip‐HMS3 in differentiating fibroblast mouse cells into adipocytes, owing to its enhanced catalytic capabilities. This study not only highlights the importance of chirality in improving the catalytic performance of natural enzymes but also provides a new perspective on developing catalytic systems that can endow natural enzymes with higher catalytic performances.
