[PMID: 35653959 DOI: 10.1016/j.talanta.2022.123566] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 05/08/2022] [Accepted: 05/16/2022] [Indexed: 12/20/2022]
Abstract
The effective trypsin purification methods should be established since trypsin plays a crucial role in biosome. In this work, a novel ternary magnetic composite adsorbent (MnFe2O4-MWCNTs@B-U-G) with the features of strong specific selectivity, good adsorption effect, simple and efficient separation process, no secondary pollution brought in was prepared by integrating the superior physicochemical properties of ternary based natural deep eutectic solvent, multi-walled carbon nanotubes and MnFe2O4. The property, composition and microtopography structure of MnFe2O4-MWCNTs@B-U-G were characterized in detail. Combined with magnetic solid-phase extraction, MnFe2O4-MWCNTs@B-U-G was utilized to adsorb trypsin. Response surface methodology experiment was prepared under Box-Behnken design to optimize the adsorption conditions and the results showed that the practical maximum adsorption capacity for trypsin was 1020.1 mg g-1. Besides, the adsorption isotherms, adsorption kinetics, regeneration studies and method validation studies were investigated systematically to evaluate the established adsorption separation system. Mechanism exploration proved that electrostatic interaction, hydrogen bonding interaction and chelation interaction were the dominant forces for the high-performance adsorption of trypsin. The activity of trypsin after elution had been analyzed by UV-vis spectrophotometer and CD spectrometer with three methods, which illustrated that the enzyme activity, conformation and secondary structure of trypsin did not change significantly during the adsorption-desorption process. In addition, the proposed method was successful and practical applicability to isolation trypsin from crude bovine pancreas. As a result, due to the superiority of the MnFe2O4-MWCNTs@B-U-G, the proposed method not only exhibites high-performance adsorption of trypsin, but also provides a green and sustainable potential value in the adsorption of biomacromolecule.

Abstract
Supercritical carbon dioxide (Sc-CO2) is an alternative tool to extract lipid for the production of fish oil and enzyme from fish by-products (FBPs). In the application of Sc-CO2, this review covers sample preparation, lipid extraction operation, and characterization of fish oil and enzyme as final products. Generally, the fish samples with moisture content less than 20% and particle size less than 5 mm are considered before lipid extraction with Sc-CO2. Sc-CO2 parameters, such as pressure (P), temperature (T), extraction time (text), and flow rate (F), for simultaneous recovery of fish oil, protein, and enzyme were found to be less severe (P: 10.3-25 MPa; T: 25-45 °C, text: 20-150 min; F: 3-50 g/min) than the extraction of fish oil alone (P: 10-40 Mpa; T: 35-80 °C; text: 30-360 min; F: 1-3000 g/min). The enzyme from the Sc-CO2 defatted sample showed higher activity up to 45 U/mg due to lower denaturation of protein as compared to the organic solvent treated sample albeit both samples having similar pH (6-10) and temperature stability (20-60 °C). Overall, mild extraction of lipid from FBPs using Sc-CO2 is effective for the production of enzymes suitable in various industrial applications. Also, fish oil as a result of extraction can be produced as a health product with high polyunsaturated fatty acids (PUFAs) and low contamination of heavy metals.

Abstract
Serine proteases are thought to play a key role in the muscle softening of gazami crab (Portunus trituberculatus) during storage. A serine protease, Pt-sp2, was purified from the hepatopancreas of gazami crab using ammonium sulfate precipitation, anion-exchange and gel filtration chromatography, and was analyzed by mass spectrometry, transcriptome and bioinformatics. It revealed that Pt-sp2 was trypsin-like, with no 100% identical proteins in the NCBI database. The molecular weight of Pt-sp2 was approximately 37.2 kDa. Its optimum pH and temperature were 9.0 and 50 °C, respectively, using t-Butyloxy‑carbonyl-Phe-Ser-Arg-4-methyl-coumaryl-7-amide as a substrate. Pt-sp2 was activated in the presence of Ca2+. Both soybean trypsin inhibitor and Nα-Tosyl-l-lysine chloromethyl ketone hydrochloride completely suppressed Pt-sp2 activity, while it was only partially inhibited by phenylmethylsulfonyl fluoride and EDTA. However, PMSF, Pepstatin A and cystatin inhibitor E-64 showed no inhibition on Pt-sp2 protease activity. The Km value of Pt-sp2 was 0.82 μM, and Pt-sp2 effectively hydrolyzed myofibrillar protein at 37 °C.

Abstract
Este estudio se enfocó en recuperar proteasas alcalinas de vísceras de Scomberomorus sierra mediante cromatografía de interacción hidrofóbica. Tres proteasas alcalinas se lograron separar parcialmente usando esta técnica cromatográfica; dos de ellas con pesos moleculares de 19 y 31 kDa fueron identificadas como enzimas tipo tripsina de acuerdo a ensayos de inhibición. La proteasa alcalina con peso molecular de 31 kDa, única enzima aislada, fue purificada bajo las siguientes condiciones cromatográficas: sulfato de amonio l3% (p/v) y etilenglicol al 27% (p/v); esta enzima mostró actividad máxima a pH 9 – 10 y 50 – 60 °C y fue fuertemente inhibida por el inhibidor de tripsina de soya (SBTI) como por el inhibidor de tripsina porcina (TPI). Una tercera proteasa alcalina con peso molecular de 20 kDa fue parcialmente separada e inhibida por tosil fenilalanil clorometil cetona (TPCK), la cual mostró actividad óptima a pH 9 – 11 y 60 °C. Estos resultados muestran que las vísceras de Scomberomorus sierra podrían ser de utilidad como fuente de proteasas.

Abstract
In fishes, trypsins are adapted to different environmental conditions, and the biochemical and kinetic properties of a broad variety of native isoforms have been studied. Proteolytic enzymes remain in high demand in the detergent, food, and feed industries; however, our analysis of the literature showed that, in the last decade, some fish trypsins have been studied for the synthesis of industrial peptides and for specific biomedical uses as antipathogenic agents against viruses and bacteria, which have been recently patented. In addition, innovative strategies of trypsin administration have been studied to ensure that trypsins retain their properties until they exert their action. Biomedical uses require the production of high-quality enzymes. In this context, the production of recombinant trypsins is an alternative. For this purpose, E. coli-based systems have been tested for the production of fish trypsins; however, P. pastoris-based systems also seem to show great potential in the production of fish trypsins with higher production quality. On the other hand, there is a lack of information regarding the specific structures, biochemical and kinetic properties, and characteristics of trypsins produced using heterologous systems. This review describes the potential uses of fish trypsins in biomedicine and the enzymatic and structural properties of native and recombinant fish trypsins obtained to date, outlining some prospects for their study.

Abstract
The present study describes the purification and physicochemical and biochemical characterization of trypsin-like protease from green-seeded chickpea (Cicer arientum). The crude extract of chickpea trypsin (CpT) was obtained by homogenization followed by differential ammonium sulfate precipitation. The CpT was purified by ion-exchange chromatography on diethylaminoethyl (DEAE) column, pre-equilibrated with 20 mM tris-CaCl2 buffer (pH 8.2) with a flow rate of 0.5 mL min-1. The molecular weight and purity of ∼23 kDa of CpT were determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Activity of protease was determined using Nα-benzoyl-DL-arginine-p-nitroanilide as chromogenic substrate and CpT purified showed a specific inhibitor activity of 26978.7697 U mg-1, fold purity of 9.8, and the yield of 70.2%. The characterization was performed for thermal stability, pH profile, and effect of various inhibitors on enzymatic activity. The protein isolated showed stability in the neutral to mild alkaline pH range and thermostability up to 50°C. CpT confirmed its serine nature as it was appreciably inhibited by serine protease inhibitors (maximum 6%), whereas metalloprotease inhibitors barely affected the activity of the enzyme (85%). To the best of our knowledge, it is first reported on purification of protease with trypsin-like properties, from this source.

Abstract
Commercial fishery processing results in discards up to 50% of the raw material, consisting of scales, shells, frames, backbones, viscera, head, liver, skin, belly flaps, dark muscle, roe, etc. Besides, fishing operations targeted at popular fish and shellfish species also result in landing of sizeable quantity of by-catch, which are not of commercial value because of their poor consumer appeal. Sensitivity to rapid putrefaction of fishery waste has serious adverse impact on the environment, which needs remedial measures. Secondary processing of the wastes has potential to generate a number of valuable by-products such as proteins, enzymes, carotenoids, fat, and minerals, besides addressing environmental hazards. Fishery wastes constitute good sources of enzymes such as proteases, lipases, chitinase, alkaline phosphatase, transglutaminase, hyaluronidase, acetyl glycosaminidase, among others. These enzymes can have diverse applications in the seafood industry, which encompass isolation and modification of proteins and marine oils, production of bioactive peptides, acceleration of traditional fermentation, peeling and deveining of shellfish, scaling of finfish, removal of membranes from fish roe, extraction of flavors, shelf life extension, texture modification, removal of off-odors, and for quality control either directly or as components of biosensors. Enzymes from fish and shellfish from cold habitats are particularly useful since they can function comparatively at lower temperatures thereby saving energy and protecting the food products. Potentials of these applications are briefly discussed.
