Abstract
BACKGROUND S. lividans TK24 is a popular host for the production of small molecules and the secretion of heterologous protein. Within its large genome, twenty-nine non-essential clusters direct the biosynthesis of secondary metabolites. We had previously constructed ten chassis strains, carrying deletions in various combinations of specialized metabolites biosynthetic clusters, such as those of the blue actinorhodin (act), the calcium-dependent antibiotic (cda), the undecylprodigiosin (red), the coelimycin A (cpk) and the melanin (mel) clusters, as well as the genes hrdD, encoding a non-essential sigma factor, and matAB, a locus affecting mycelial aggregation. Genome reduction was aimed at reducing carbon flow toward specialized metabolite biosynthesis to optimize the production of secreted heterologous protein. RESULTS Two of these S. lividans TK24 derived chassis strains showed ~ 15% reduction in biomass yield, 2-fold increase of their total native secretome mass yield and enhanced abundance of several secreted proteins compared to the parental strain. RNAseq and proteomic analysis of the secretome suggested that genome reduction led to cell wall and oxidative stresses and was accompanied by the up-regulation of secretory chaperones and of secDF, a Sec-pathway component. Interestingly, the amount of the secreted heterologous proteins mRFP and mTNFα, by one of these strains, was 12 and 70% higher, respectively, than that secreted by the parental strain. CONCLUSION The current study described a strategy to construct chassis strains with enhanced secretory abilities and proposed a model linking the deletion of specialized metabolite biosynthetic clusters to improved production of secreted heterologous proteins.

Abstract
Luteolin, a plant-derived flavonoid, was found to exert effective inhibitory effect to peroxidase activity in a non-competitive manner with an IC50 of (6.62 ± 0.45) × 10-5 mol L-1. The interaction between luteolin and peroxidase induced the formation of a static complex with a binding constant (Ksv) of 7.31 × 103 L mol-1 s-1 driven by hydrogen bond and hydrophobic interaction. Further, the molecular interaction between luteolin and peroxidase resulted in intrinsic fluorescence quenching, structural and conformational alternations which were determined by multispectroscopic techniques combined with computational molecular docking. Molecular docking results revealed that luteolin bound to peroxidase and interacted with relevant amino acid residues in the hydrophobic pocket. These results will provide information for screening additional peroxidase inhibitors and provide evidence of luteolin's potential application in preservation and processing of fruit and vegetables and clinical disease remedy.

Abstract
Abstract
Background
Due to versatility in reaction catalyzed by peroxidases, they have potential applications in different areas in the health sciences, food industry, and diagnostic purposes. Therefore, the aim of this study is to investigate the properties of peroxidase from ginger to be meeting the perquisites of several applications.
Results
The cationic peroxidase (GPII) was purified to homogeneity by anion exchange chromatography using DEAE–Sepharose column followed by cation exchange chromatography using CM–Sepharose column and finally Sephacryl S-200 column. The molecular mass of GPII was 42 kDa. GPII shows oxidizing activity with several phenolic compounds by using H2O2 as the second substrate. The natural plant phenolic compounds as pyrogallol, catechol, and guaiacol were found to be excellent electron donors for the enzyme compared to other phenolic compounds. GPII exhibited Km values of 3.1 and 7.1 mM and Vmax values of 0.6 and 0.31 units/assay using H2O2 and guaiacol as substrates, respectively. The enzyme exhibited maximal peroxidase activity at broad pH’s 6.0–7.5 and 50 °C. GPII was thermal stable up to 50 °C and retained 66% of its activity at 70 °C after 1 h incubation. The GPII activated by most divalent cations tested and inhibited by Hg2+ and Cu2+ cations.
Conclusion
PGII could be used in several applications due to its catalytic properties, thermal stability, broad pH, and acting on several phenolic compounds.

Purification and characterization of peroxidases from garden cress sprouts and their roles in lignification and removal of phenol and p-chlorophenol. J Food Biochem 2020; 45:e13526. [PMID: 33140461 DOI: 10.1111/jfbc.13526] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 09/11/2020] [Accepted: 09/28/2020] [Indexed: 12/14/2022]
Abstract
The study aims to evaluate the relation between peroxidases of day-6 garden cress sprouts and phenolic compounds. Three cationic, three anionic, and two unbounded peroxidases were separated from day-6 garden cress sprouts. Cationic (GCP1) and anionic (GCP2) peroxidases were purified with molecular masses of 25 and 40 kDa, respectively. The Km values of GCP1 toward H2 O2 and guaiacol were lower than GCP2. The anionic GCP2 exhibited high affinity toward some lignin monomers, sinapyl alcohol, coniferyl alcohol, cinnamic and ferulic acids. Therefore, GCP2 is considered as a lignin peroxidase and contributed in lignin synthesis. The activity of GCP1 and GCP2 was stable at a wide pH range 5.5-8.0 and 6.0-7.5, respectively. Both peroxidases showed the same thermal stability range 20-50°C. GCP2 was more resistant against the effect of metal ions than GCP1. GCP2 showed high ability to remove of phenol and p-chlorophenol from effluent compared to GCP1. PRACTICAL APPLICATIONS: Generally, garden cress is used as a test plant to conduct biomonitoring of pollution in urban soil on a wide scale because of its simplicity, sensitivity, and cost-effectiveness. Peroxidase is an important antioxidant enzyme, which elevated when plant subjected to pollution. Recently, we reported that the increase of peroxidase activity was strongly correlated with high phenolic content and antioxidant activity during the germination of garden cress. In the present study, anionic peroxidase GCP2 may play an important role in lignification process and removal of phenol and p-chlorophenol from polluted soil/wastewater as well as resisted the harmful effect of heavy metals. Cationic peroxidase GCP1, as a natural scavenger, had high affinity toward H2 O2 coupled to oxidation of some plant phenolic compounds suggesting its role in consuming of excess H2 O2 .

Abstract
We purified a serine protease from Ficus carica latex. Serine protease had a high tendency to hydrolyze fibrinogin. Serine protease inhibited blood coagulation.
Ficus carica is one of the most popular and edible plants. Its trees emanate latex of high medical importance. The well-studied procoagulant effect of ficin is a hallmark of this latex which protrudes an interesting question of how can the plant control this effect? In the present work, we purified and characterized a serine protease (FPIII) with fibrinolytic activity from F. carica latex and study the anticoagulant character of the latex. FPIII was inhibited by PMSF and its molecular weight was 48 kDa. The optimum pH and temperature of FPIII were detected at 8.5 and 60 °C, respectively. The activation energy of FPIII was 7 kcal/mol and was thermal stable up to 60 °C. FPIII tended to hydrolyze different protein substrates and showed a good catalytic efficiency (Kcat/Km). The anticoagulant effects and fibrinogenolytic activities of latex crude extract and FPIII were detected, which controls the procoagulant effect of ficin.

Abstract
Echinococcosis/hydatidosis is one of the most important parasitic zoonotic diseases in the world. Cystic echinococcosis increases public health and socio-economic concern due to considerable morbidity rates that give rise to elevated economic losses both in the public health part and in the farm animal field. The enzyme linked immunosorbent assay (ELISA) is consider the more accurate tool for diagnosis of hydatidosis in camels. In the present study, affinity purified Echinococcus granulosus (E. granulosus) antigens (APA) were purified from crude hydatide E. granulosus germinal layer proteins for detection of E. granulosus antibodies in infected camels, using affinity matrix (camel IgGs coupled to CNBr-activated Sepharose). The electrophoretic profile of the APA showed that it was separated into two bands; one major band of 130 kDa and one minor band at 55 kDa. These antigens were used successfully as specific coating antigenic proteins in detection of echinococcosis in camel. In a trial to prepare an anti-camel IgGs peroxidase conjugate; peroxidase enzyme was purified from turnip roots (TPOD) using ammonium sulfate precipitation and affinity chromatography on phenyl Sepharose CL-4B. The purified TPOD showed a major band at 35 kDa. Rabbit anti-camel IgG antibodies (AC IgGs) were prepared then purified using affinity chromatography on Protein G-Sepharose. The TPOD, and commercial HRP for comparison, enzymes were conjugated to AC IgGs using 1%, 5% and 10% glutaraldehyde. The results revealed that the HRP was much better than TPOD in conjugation with AC-IgG antibodies and the 10% glutaraldehyde concentration was the most efficient concentration with ELISA titer 1:50.
