<p>The main protease Mpro is a key protein in the lifecycle of the SARS-CoV-2 virus. Mpro cleaves the viral polyproteins at the C-terminal end of a glutamine residue in recognition sequences containing Leu-Gln-(Ser, Ala, Gly) motifs (Rut et al, 2020).  As SARS-CoV-2 MPro has no closely related homologues in humans, it represents an attractive drug target (Ullrich and Nitsche, 2020). In summary, the Mpro protease is a chymotrypsin-like cysteine protease, requires homodimerisation for proteolytic activity, cleaves the viral polyproteins in 11 distinct sites, exclusively after a glutamine residue. A fluorogenic substrate for Mpro assays is Ac-Abu-Tle-Leu-Gln-AMC.The protein amount or better its concentration in solution is quantified using either A280 (absorption at 280 nm with its specific absorption coefficient) or using the Bradford assay (uses the dye Coomassie Brilliant Blue). Both of these methods quantify the total amount of protein in a sample, no matter what the oligomerization state is.</p>

<p>Penase (Penicillinase) is an enzyme, which is a type of β-lactamase sourced from various bacterial strains capable of deactivating penicillin. It accomplishes this by targeting the β-lactam ring, a crucial structural component of penicillin antibiotics, and hydrolyzing it, thereby neutralizing the antibiotic effect. This enzymatic action is a defense mechanism employed by certain bacteria to survive in environments saturated with penicillin-based antibiotics.</p>

<p>This product shows beta-lactamase activity against clinically relevant beta-lactam antibiotics such as penicillins, carbapenems and cephalosporins. This product may be of particular interest for laboratory teams who require the sterility testing of biological specimens or for environmental monitoring applications.</p>

<p>Proteinase K, freeze-dried, recombinant is an enzyme preparation used extensively in molecular biology and biochemistry. It is derived through recombinant DNA technology, producing a highly pure enzyme that is expressed in a non-pathogenic host. Its mode of action involves the non-specific cleavage of peptide bonds in proteins, making it a critical tool for protein digestion.</p>

Lipases belong to the family of esterases and naturally act on triglycerides at lipid-water interfaces catalyzing hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications. Lipase 38 was shown to hydrolyze p-Nitrophenyl esters of acetate (27 % activity compared to butyrate), butyrate (100 %), octanoate (9 %) and caprate (5 %).</p>

<p>Glucose-6-phosphate dehydrogenase (G6PD, G6PDH; EC 1.1.1.49) is an enzyme that catalises the following reaction:  D-glucose 6-phosphate + NADP+ + H2O ⇌ 6-phospho-D-glucono-1,5-lactone + NADPH + H+  One unit of G6PD will oxidize 1.0 µmole of D-glucose 6-phosphate to 6-phospho-D-glucono-1,5-lactone per min in the presence of NAD+ at pH 7.8 and 30 °C. NADP+ is available here.</p>

<p>CalB 02 is a lipase enzyme, which is a biocatalyst derived from the yeast Candida antarctica. It functions primarily by catalyzing the hydrolysis of ester bonds. This enzymatic action is due to the unique structure of the active site, which allows for precise substrate specificity and stereoselectivity.</p>

<p>CalB 10 is an industrial enzyme, specifically a lipase, which is derived from microbial sources, most commonly expressing the lipase B from Candida antarctica. It operates through the hydrolysis of ester bonds in lipids, enabling the conversion of triglycerides into glycerol and free fatty acids. This catalytic action is facilitated via its active site, where the nucleophilic serine residue attacks the carbonyl carbon of the substrate, forming a tetrahedral intermediate that eventually results in bond cleavage and product release.</p>

<p>Alpha Amylase is an enzyme that catalyses hydrolysis of large polysacharides into smaller fragments. Alpha amylase targets alpha bonds of 1→4 glycosidic linkages of poly- and oligosaccharides with three or more D-glucose units.
