Alpha-L-iduronidase is a glycoside hydrolase enzyme that cleaves the non-reducing, terminal alpha-L-iduronic acid residues from polysaccharides and oligosaccharides. Alpha-L-iduronidase is involved in the lysosomal degradation of glycosaminoglycans and its deficiency leads to the accumulation of dermatan sulphate and heparan sulphate in tissues, a condition known as mucopolysaccharidosis I (MPS I). Alpha-L-iduronidase activity can be detected and quantified in an assay using a fluorogenic substrate 4MU-alpha-L-idopyranosiduronic acid. Alpha-L-iduronidase is also used in a 2-step assay for Hunter syndrome (MPS II) testing in combination with 4-MU-alpha-L-idopyranosiduronic acid 2-sulphate.
This enzyme is supplied as a 2 mg/mL aqueous solution in 25 mM sodium acetate, 150 mM NaCl, 50% glycerol, pH 5.0 from a bacterial source, recombinantly expressed in Escherichia coli (see application notes for more details). Alpha-L-iduronidase is also available as lyophilisate (FA181881)

Cholesterol dehydrogenase (EC 1.1.1.840) is NADP+-dependant oxidoreductase, that catalyses the following reaction:cholesterol + NADP+ + H2O → cholest-4-en-3-one + NADPH + H+This is achieved by oxidizing alcohol hydroxy-group into ketone. One unit of cholesterol dehydrogenase will produce 1.0 μmole of cholest-4-en-3-one per minute at pH 8.5 and 25 °C.

L-Leucine dehydrogenase (Leucine dehydrogenase, systematic name L-leucine:NAD+ oxidoreductase (deaminating); EC 1.4.1.9) is an enzyme that catalyzes the following reaction:  L-leucine + H2O + NAD+ ⇌ 4-methyl-2-oxopentanoate + NH3 + NADH + H+  One unit of L-Leucine dehydrogenase will convert 1.0 µmole of L‑leucine into 4-methyl-2-oxopentanoate per min at pH 10.5 and 37 °C in the presence of NAD+. The enzyme requires NAD+ as a cofactor, it is available here.

20mg/ml aq. solution.  Proteinase K is used for the general digestion of proteins and removal of protein contamination in nucleic acids. Addition of Protease K also stabilizes nucleic acids but degrading any nucleases present. Proteinase K is active in wide range of pH range, in the presence of SDS, urea and Guanidinium chloride at low to moderate concentrations. Proteinase K is also known under names of protease K and endopeptidase K.

Glucosyltransferase205-freeze dried is an enzyme preparation that is commonly used in biochemical and molecular biology research. It is derived from microbial sources, often from bacteria or fungi that are known for producing extracellular enzymes. The primary mode of action of Glucosyltransferase205 involves catalyzing the transfer of glucose residues from donor molecules, such as UDP-glucose, to acceptor molecules, forming glycosidic bonds. This enzymatic activity is crucial in the biosynthesis of polysaccharides, which are essential components in various biological structures and processes.

Aldehyde dehydrogenase (EC 1.2.1.3) is the enzyme that catalyzes oxidation of aldehydes to carboxilic acids, using NAD+ as a cofactor in the following reaction: R-CHO + NAD+ + H2O → R-COOH + NADH + H+    One enzyme unit will oxidize 1.0 μmole of acetaldehyde to acetic acid per min at 25 °C at pH 8.0 in the presence of β-NAD+, potassium and thiols.

This enzymatic activity results in complex carbohydrate structures essential for various biological processes.

SPM-1 (β-Lactamase) is a metallo-β-lactamase enzyme, which is derived from certain Gram-negative bacteria, such as Pseudomonas aeruginosa. This enzyme is characterized by its ability to hydrolyze a broad spectrum of β-lactam antibiotics, including penicillins, cephalosporins, and carbapenems, due to the presence of a zinc ion in its active site. The zinc ion plays a crucial role in the catalytic mechanism by facilitating the cleavage of the β-lactam ring, rendering the antibiotic ineffective against bacterial cell wall synthesis.

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.
