Enzymes dans les Protéines Recombinantes

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.

A general purpose growth medium supplemented with LacBuster™ to effectively neutralize beta-lactam antibiotics. This product is suitable for the cultivation of a wide variety of microorganisms for environmental monitoring within the pharmaceutical industry and for high performance monitoring of your isolators and clean rooms during beta lactam manufacture

Lipases belong to the family of esterases and naturally act on triglycerides at lipid-water interfaces. Lipases/esterases can be used as versatile tools in hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications.

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. Systematic name of alpha-amylase is 4-α-D-glucan glucanohydrolase, EC 3.2.1.1. One unit of Alpha Amylase will produce 1.0 mg of maltose from starch in 1 minute at pH 4.9 and 40 °C.

Deoxyribonuclease II (DNase II, deoxyribonucleate 3'-nucleotidohydrolase, acid deoxyribonuclease, acid DNase, EC 3.1.22.1) is an endonuclease that cleaves DNA, yielding 3'-phosphate-terminated polynucleotides with a free hydroxyl group on position 5'. One unit of the DNase II will increase the absorbance of 260nm light at a rate of 0.001/minute in 1 ml reaction volume at pH 4.6 and 25°C.

Sialic acid aldolase - Aqueous solution is an enzyme preparation used extensively in biochemical and biotechnological applications. It is derived from microbial sources, where it is expressed and purified to high levels for research purposes. Sialic acid aldolase acts by catalyzing the reversible aldol reaction between N-acetylneuraminic acid (sialic acid) and pyruvate, facilitating the cleavage or synthesis of sialic acid.

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.

Lipase 70 recombinantly expressed in E. coli comes in a spray-dried formulation. It has its pH optimum at 6-8 and temp. optimum at 35-45°C. 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 70 was shown to hydrolyze p-Nitrophenyl esters of butyrate (100 % activity), octanoate (62 %), laurate (15 %), palmitate (4 %), stearate (3 %), arachidate (2 %) and behenate (0.2 %).

Ready to use beta-lactamase solution targeting beta-lactam antibiotics such as penicillins, carbapenems and cephalosporins. According to US Pharmacopeia (USP <71>) and EP, LacBusterTM-L is suitable for sterility testing methods such as membrane filtration and direct inoculation.

Porcine liver esterase (EC 3.1.1.1) is an enzyme that catalyses ester hydrolysis, producing a fatty acid and an alcohol. One unit of esterase will hydrolyze 1.0 μmole of ethyl butyrate to butyric acid and ethanol per min at pH 8.0 and 25 °C. Ethyl butyrate is available here.

DNA ligase (ATP) is an enzyme (EC 6.5.1.1) that ligates DNA strands, repairing nicks in double-standed DNA and coupling blunt-ended or cohesive DNA fragments. It requires 3′ hydroxyl and 5′ phosphate nucleoside ends for ligation and ATP as a cofactor.

Endoglycosidase H (systematic name glycopeptide-D-mannosyl-N4-(N-acetyl-D-glucosaminyl)2-asparagine 1,4-N-acetyl-β-glucosaminohydrolase, EC 3.2.1.96) is a highly specific enzyme, that cleaves asparagine-linked mannose rich oligosaccharides. One unit of Endoglycosidase H will remove >95% of the carbohydrate from 10μg of denatured RNase B in 1 hour at 37°C in a total reaction volume of 10μl.The product EEH01.7 is available as a large-scale bulk supply of liquid enzyme solution and is intended for use in the chemical, diagnostic, pharmaceutical and related industries.For removal of all N-linked carbohydrates from proteins see Cymit Quimica's PNGase F enzymes (PNG01.3 - vials for research and PNG01.7 - large-scale bulk supply)
