Abstract
A new extracellular protease from Bacillus subtilis strain MPK with collagenolytic activity was isolated and purified. Fish skin which otherwise would be treated as waste is used as substrate for the production of protease. Using various techniques such as ammonium sulphate precipitation and ion exchange chromatography, protease was purified and characterized subsequently. Protease of approximately 61 kDa molecular weight was purified by 135.7-fold with 18.42% enzyme recovery. The protease showed effective properties like pH and temperature stability over a broad range with optimum pH 7.5 and temperature 60 °C. Km and Vmax were found to be 1.92 mg ml-1 and 1.02 × 10-4 mol L-1 min-1, respectively. The protease exhibited stability in various ions, surfactants, inhibitors and organic solvents. Subsequently, the protease was successfully utilized for collagen hydrolysis to generate collagen peptides; thus, the produced protease would be a potential candidate for multifaceted applications in food and pharmaceutical industries due to its significant characteristics and collagenolytic properties.

Abstract
Collagenases are proteases able to degrade native and denatured collagen, with broad applications such as leather, food, and pharmaceutical industries. The aim of this research was to purify and characterize a collagenase from Streptomyces antibioticus. In the present work, the coffee ground substrate provided conditions to obtaining high collagenase activity (377.5 U/mL) using anion-exchange DEAE-Sephadex G50 chromatographic protocol. SDS-PAGE revealed the metallo-collagenase with a single band of 41.28 kDa and was able to hydrolyzed type I and type V collagen producing bioactive peptides that delayed the coagulation time. The enzyme activity showed stability across a range of pH (6.0-11) and temperature (30-55 °C) with optima at pH 7.0 and 60 °C, respectively. Activators include Mg+2, Ca+2, Na+, K+, while full inhibition was given by other tested metalloproteinase inhibitors. Kinetic parameters (Km of 27.14 mg/mol, Vmax of 714.29 mg/mol/min, Kcat of 79.9 s-1 and Kcat/Km of 2.95 mL/mg/s) and thermodynamic parameters (Ea of 65.224 kJ/mol, ΔH of 62.75 kJ/mol, ΔS of 1.96 J/mol, ΔG of 62.16 kJ/mol, ΔGE-S of 8.18 kJ/mol and ΔGE-T of -2.64 kJ/mol) were also defined. Coffee grounds showed to be an interesting source to obtaining a collagenase able to produce bioactive peptides with anticoagulant activity.

Abstract
Background: The collagenase encoding gene col was cloned into a pP43NMK vector and amplified in Escherichia coli JM109 cells. The shuttle vector pP43NMK was used to sub-clone the col gene to obtain the vector pP43NMK-col for the expression of collagenase in Bacillus subtilis WB600. The enzyme was characterized and the composition of the expression medium and culture conditions were optimized. Methods: The expressed recombinant enzyme was purified by ammonium sulfate, ultrafiltration, and through a nickel column. The purified collagenase had an activity of 9405.54 U/mg. Results: The recombinant enzyme exhibited optimal activity at pH 9.0 and 50 °C. Catalytic efficiency of the recombinant collagenase was inhibited by Fe3+ and Cu2+, but stimulated by Co2+, Ca2+, Zn2+, and Mg2+. The optimal conditions for its growth were at pH 7.0 and 35 °C, using 15 g/L of fructose and 36 g/L of yeast powder and peptone mixture (2:1) at 260 rpm with 11% inoculation. The maximal extracellular activity of the recombinant collagenase reached 2746.7 U/mL after optimization of culture conditions, which was 2.4-fold higher than that before optimization. Conclusions: This study is a first attempt to recombinantly express collagenase in B. subtilis WB600 and optimize its expression conditions, its production conditions, and possible scale-up.

Abstract
Cry toxins produced by Bacillus thuringiensis are well known for their high insecticidal activities against Lepidoptera, Diptera, and Coleoptera; however, their activities against Aphididae are very low. Recently, it has been reported that a Cry41-related toxin exhibited moderate activity against the aphid Myzus persicae, and thus, it is highly desirable to uncover its unique mechanism. In this paper, we report that Cathepsin B, calcium-transporting ATPase, and symbiotic bacterial-associated protein ATP-dependent-6-phosphofructokinase were pulled down from the homogenate of M. persicae as unique proteins that possibly bound to Cry41-related toxin. Cathepsin B has been reported to cleave and inactivate antiapoptotic proteins and plays a role in caspase-initiated apoptotic cascades. In this study, Cathepsin B was expressed in Escherichia coli and purified, and in vitro interaction between recombinant Cathepsin B and Cry41-related toxin was demonstrated. Interestingly, we found that addition of Cry41-related toxin obviously enhanced Cathepsin B activity. We propose a model for the mechanism of Cry41-related toxin as follows: Cry41-related toxin enters the aphid cells and enhances Cathepsin B activity, resulting in acceleration of apoptosis of aphid cells.

Collagenase-assisted wound bed preparation: An in vitro comparison between Vibrio alginolyticus and Clostridium histolyticum collagenases on substrate specificity. Int Wound J 2019; 16:1013-1023. [PMID: 31148413 DOI: 10.1111/iwj.13148] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Revised: 05/02/2019] [Accepted: 05/11/2019] [Indexed: 11/29/2022] Open
Abstract
Bacterial collagenase from the aerobic non-pathogenic Vibrio alginolyticus chemovar iophagus is an extracellular metalloproteinase. This collagenase preparation is obtained through a fermentation process and is purified chromatographically, resulting in a highly purified 82-kDa single-band protein that does not contain non-specific proteases or other microbial impurities. V. alginolyticus collagenase was added to a hyaluronan (HA)-based device to develop a novel debriding agent to improve the treatment of ulcers, necrotic burns, and decubitus in the initial phase of wound bed preparation. In this study, an in vitro biochemical characterisation of V. alginolyticus collagenase versus a commercial preparation from a Clostridium histolyticum strain on various dermal extracellular matrix (ECM) substrates was performed. V. alginolyticus collagenase demonstrated its ability to carry out the enzymatic cleavage of the substrate, allowing a selective removal of necrotic tissues while sparing healthy tissue, as reported in clinical studies and through routine clinical experience. in vitro tests under physiological conditions (pH, presence of Ca++, etc.) have demonstrated that V. alginolyticus collagenase exhibits very poor/limited non-specific proteolytic activity, whereas the collagenase preparation from C. histolyticum is highly active both on collagen and on non-collagenic substrates. This finding implies that while the V. alginolyticus enzyme is fully active on the collagen filaments that anchor the necrotic tissue to the wound bed, it does not degrade other minor, but structurally important, components of the dermal ECM. This feature could explain why collagenase preparation from V. alginolyticus has been reported to be much gentler on perilesional, healthy skin.
