Protease enzymes break down proteins and are essential for many biological processes, including digestion, cellular regulation and blood clotting. They are also used in many industrial and biotechnological applications for example in food processing and in detergents.

Phosphorylase B is an enzymatic protein, specifically an isoform of glycogen phosphorylase, derived from rabbit muscle. This enzyme plays a critical role in glycogen metabolism by catalyzing the phosphorolytic cleavage of α(1→4) glycosidic bonds in glycogen, releasing glucose-1-phosphate. The rabbit muscle source provides a well-studied model due to its high enzyme activity and availability, facilitating in-depth biochemical and structural analysis.

Cellulose catalase is an enzyme-based product, designed specifically to act as a catalyst in the oxidative processes associated with cellulose applications. It is derived from a microbial source, where bacilli or fungi are employed to produce robust catalase enzymes in a fermentation process. The mode of action involves the catalase enzyme’s ability to facilitate the decomposition of hydrogen peroxide into water and oxygen, thereby reducing oxidative damage during cellulose processing.

Nitrilase (nitrile aminohydrolase; EC 3.5.5.1) in an enzyme that catalyzes hydrolysis of nitriles to carboxilic acids and ammonia:  R-CN + 2 H2O → R-COO- + NH4+  One unit of nitrilase will yield 1.0 μmol of ammonia per minute under optimal reaction conditions using acrylonitrile as a substrate.

α-Mannosidase (α-D-mannopyranosidase, 1,2-α-mannosidase, 1,2-α-D-mannosidase, exo-α-mannosidase, α-D-mannosidase, systematic name α-D-mannoside mannohydrolase; EC 3.2.1.24) is an enzyme that cleaves α-mannose to produce glucose. One unit of α-Mannosidase will hydrolyze 1.0 µmole of chromogenic phosphate mimic p-nitrophenyl-α-p-mannoside to p-nitrophenol in 1 minute at pH 5.0 and 37°C.

Superoxide dismutase coupled to polyethylene glycol. Superoxide dismutase (EC 1.15.1.1) is an enzyme that catalyzes the following reaction:  2 H+ + 2 O2− → O2 + H2O2  thus converting an extremely reactive and cytotoxic superoxide radical into oxygen and (significantly less reactive) hydrogen peroxide.

Pyruvate kinase (from Rabbit muscle), ammonium sulfate suspension is an enzyme product, which is a purified protein extracted from the muscle tissue of rabbits. This enzyme plays a crucial role in glycolysis, specifically catalyzing the transphosphorylation of phosphoenolpyruvate (PEP) to pyruvate, generating ATP from ADP in the process. This step is a key regulatory point in the glycolytic pathway, which is essential for cellular energy production.

Mannitol dehydrogenase (MDH, mannitol 2-dehydrogenase, EC 1.1.1.67) is an enzyme that catalyzes the following reaction:  D-mannitol + NAD+ ⇌ D-fructose + NADH + H+  One unit of mannitol dehydrogenase will generate 1.0 μmole of D-fructose per min in the presence of NAD+ at pH 8.6 and 40°C. NAD+ is available here and NADH is available here, depending on whether you require the reaction to proceed from left to right or from righ to left, respectively.

eXrase DNA endonuclease from enGenes is a recombinant endonuclease from Serratia marcescens produced in E. coli. Effectively and efficiently degrades all forms of DNA and RNA, reducing sample viscosity without proteolytic activity. As effective and efficient as other nucleases on the market, eXrase DNA endonuclease is the most cost-effective way to improve proteins yields and improve sample handing. Presented as a ready to use colourless liquid, formulated in Tris buffer at pH 8.0 with 50 % glycerol (v/v).  This research grade eXrase has low endotoxin, max 0.25 EU/kU.eXrase DNA endonuclease is suitable for the effective breakdown of nucleic acids in numerous biotech settings:  • Removal of residual host DNA from biotechnological products to meet regulatory standards • Reduction of viscosity and streamlined purification in downstream processing of fermentation procedures. • Reduction of viscosity in in upstream fermentation processes • Extraction and/or synthesis of flavouring nucleotides • Enhanced bioavailability of nucleotides in specific feed products • DNA degradation for the removal or prevention of biofilm formationeXrase DNA endonuclease from enGenes is made by a proprietary microbial fermentation process utilizing Escherichia coli cells. This enzyme facilitates the hydrolysis of phosphodiester bonds in various forms of DNA and RNA, including single-stranded, double-stranded, linear, circular, or supercoiled configurations, yielding smaller oligonucleotides typically composed of 2-4 base pairs. Unit-Definition: One unit (U) of the enzyme is defined as the amount required to digest calf thymus DNA, yielding acid-soluble oligonucleotides equivalent to a ΔA260nm of 1.0 within a 30-minute timeframe at pH 8.0 and 37°C. This standardization allows for consistent measurement of enzymatic activity across different batches.
