Int J Biol Macromol 2024:135811. [PMID: 39322145 DOI: 10.1016/j.ijbiomac.2024.135811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2024] [Revised: 09/15/2024] [Accepted: 09/18/2024] [Indexed: 09/27/2024]
Abstract
Owing to the rapid advancement of in vitro synthetic biology, functional carriers capable of covalently binding target proteins from crude lysates under mild conditions have garnered escalating attention. Herein, a magnetic nanoparticle with affinity/covalent bifunction (MNP@Affi-Cova) was developed for the direct covalent immobilization of the recombinant enzyme of His-tagged birA (r-birA) from crude cell lysates in a single step. This innovative approach is attributed to the presence of chelated Ni2+ ions and epoxy groups on the surface of the beads. The fabricated magnetic nanoparticles were characterized by SEM, FT-IR spectrum, and zeta potential. The application conditions and stability of the MNP@Affi-Cova beads were systematically evaluated. Notably, the MNP@Affi-Cova beads exhibited a covalent capture efficiency of 91.25 μg r-birA/mg beads from a cell lysate supernatant containing 2.62 mg/mL crude protein. The immobilized r-birA exhibited significantly enhanced pH and thermal stability compared to the free counterpart. Additionally, the reusability of the immobilized r-birA on MNP@Affi-Cova demonstrated the retention of 76.1 % of its initial activity over ten cycles. These results suggest that the MNP@Affi-Cova presents considerable potential as a support for the covalent immobilization of recombinant His-tagged enzymes directly from crude lysates, thereby circumventing the labor-intensive purification process typically required before enzyme immobilization.

[PMID: 37103491 DOI: 10.1007/s00253-023-12523-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 03/03/2023] [Accepted: 04/10/2023] [Indexed: 04/28/2023]
Abstract
A novel chitinase gene of 888 bp from Streptomyces bacillaris was cloned and expressed in Escherichia coli BL21. The purified recombinant enzyme (SbChiAJ103) was identified as the first microbial-derived family 19 endochitinase that showed exochitinase activity. SbChiAJ103 exhibited the substrate preference for N-acetylchitooligosaccharides with even degrees of polymerization and the capability to specifically hydrolyze colloidal chitin into (GlcNAc)2. Mono-methyl adipate was employed as a novel linker for the efficient covalent immobilization of chitinase on magnetic nanoparticles (MNPs). The immobilized SbChiAJ103, SbChiAJ103@MNPs, exhibited superior pH tolerance, temperature stability, and storage stability than free SbChiAJ103. Even after incubation at 45 °C for 24 h, SbChiAJ103@MNPs could retain more than 60.0% initial activity. As a result, the enzymatic hydrolysis yield of SbChiAJ103@MNPs increased to 1.58 times that of free SbChiAJ103. Moreover, SbChiAJ103@MNPs could be reused by convenient magnetic separation. After 10 recycles, SbChiAJ103@MNPs could retain almost 80.0% of its initial activity. The immobilization of the novel chitinase SbChiAJ103 paves the way to the efficient and eco-friendly commercial production of (GlcNAc)2. KEY POINTS: • The first microbial GH19 endochitinase with exochitinase activity was reported. • Mono-methyl adipate was first employed to immobilize chitinase. • SbChiAJ103@MNPs showed excellent pH stability, thermal stability, and reusability.

Attaran Dowom S, Karimian Z, Mostafaei Dehnavi M, Samiei L. Chitosan nanoparticles improve physiological and biochemical responses of Salvia abrotanoides (Kar.) under drought stress. BMC PLANT BIOLOGY 2022; 22:364. [PMID: 35869431 PMCID: PMC9308334 DOI: 10.1186/s12870-022-03689-4] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 06/10/2022] [Indexed: 05/08/2023]
Abstract
BACKGROUND The use of organic nanoparticles to improve drought resistance and water demand characteristics in plants seems to be a promising eco-friendly strategy for water resource management in arid and semi-arid areas. This study aimed to investigate the effect of chitosan nanoparticles (CNPs) (0, 30, 60 and 90 ppm) on some physiological, biochemical, and anatomical responses of Salvia abrotanoides under multiple irrigation regimes (30% (severe), 50% (medium) and 100% (control) field capacity). RESULTS The results showed that drought stress decreases almost all biochemical parameters. However, foliar application of CNPs mitigated the effects caused by drought stress. This elicitor decreased electrolyte conductivity (35%), but improved relative water content (12.65%), total chlorophyll (63%), carotenoids (68%), phenol (23.1%), flavonoid (36.4%), soluble sugar (58%), proline (49%), protein (45.2%) in S. abrotanoides plants compared to the control (CNPs = 0). Furthermore, the activity of antioxidant enzymes superoxide dismutase (86%), polyphenol oxidase (72.8%), and guaiacol peroxidase (75.7%) were enhanced after CNPs treatment to reduce the effects of water deficit. Also, the CNPs led to an increase in stomatal density (5.2 and 6.6%) while decreasing stomatal aperture size (50 and 25%) and semi-closed stomata (26 and 53%) in leaves. CONCLUSION The findings show that CNPs not only can considerably reduce water requirement of S. abrotanoides but also are able to enhance the drought tolerance ability of this plant particularly in drought-prone areas.

Abstract
Hybrid nanoparticles composed of different biopolymers for delivery of enzyme/prodrug systems are of interest for cancer therapy. Hyaluronic acid-coated chitosan nanoparticles (CS/HA NP) were prepared to encapsulate individually an enzyme/pro-drug complex based on horseradish peroxidase (HRP) and indole-3-acetic acid (IAA). CS/HA NP showed size around 158 nm and increase to 170 and 200 nm after IAA and HRP encapsulation, respectively. Nanoparticles showed positive zeta potential values (between +20.36 mV and +24.40 mV) and higher encapsulation efficiencies for both nanoparticles (up to 90 %) were obtained. Electron microscopy indicated the formation of spherical particles with smooth surface characteristic. Physicochemical and thermal characterizations suggest the encapsulation of HRP and IAA. Kinetic parameters for encapsulated HRP were similar to those of the free enzyme. IAA-CS/HA NP showed a bimodal release profile of IAA with a high initial release (72 %) followed by a slow-release pattern. The combination of HRP-CS/HA NP and IAA- CS/HA NP reduced by 88 % the cell viability of human bladder carcinoma cell line (T24) in the concentrations 0.5 mM of pro-drug and 1.2 μg/mL of the enzyme after 24 h.
