Below you will find a brief description of each of the enzyme subclasses in which Novozymes have products, with a link to their ExPASy entry. On the Our Success Stories site, found in the menu to the left, you can read more about the use of some of our enzyme products, and how they were developed.

Oxidoreductases
Catalase
Base reaction: 2 H2O2 <=> O2 + 2 H2O

Glucose oxidases
Base reaction: Beta-D-glucose + O2 <=> D-glucono-1,5-lactone + H2 O2

Laccases
Base reaction: 4 benzenediol + O(2) <=> 4 benzosemiquinone + 2 H(2)O

Transferases
Fructosyltransferases
Base reaction: Catalyses the synthesis of fructo-oligosaccharides from sucrose.

Glucosyltransferases
Base reaction: Act as a catalyst for the transfer of a monosaccharide unit from an activated nucleotide sugar (also known as the "glycosyl donor") to an Glycosyl acceptor molecule

Hydrolases
Amylases
Base reaction: Hydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides

Cellulases
Base reaction: Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans

Lipases
Base reaction: Catalyzes the hydrolysis of ester bonds in water–insoluble, lipid substrates

Mannanases
Base reaction: Hydrolysis of (1->6)-alpha-D-mannosidic and  (1->4)-beta-D-mannosidic linkages

Pectinases
Base reaction: Hydrolysis of (1->4)-alpha-D-galactosiduronic linkages in pectate and other galacturonans

Phytases
Base reaction:
3-Phytase: Myo-inositol hexakisphosphate + H2O <=> 1D-myo-inositol 1,2,4,5,6-pentakisphosphate + phosphate
4-Phytase: Myo-inositol hexakisphosphate + H2O <=> 1D-myo-inositol 1,2,3,5,6-pentakisphosphate + phosphate
5-Phytase: Myo-inositol hexakisphosphate + H2O <=> 1L-myo-inositol 1,2,3,4,6-pentakisphosphate + phosphate

Proteases
Base reaction: A protease is any enzyme that conducts proteolysis, that is, begins protein catabolism by hydrolysis of the peptide bonds that link amino acids together in the polypeptide chain, which form a molecule of protein.

Pullulanases
Base reaction: Hydrolysis of (1->6)-alpha-D-glucosidic linkages in pullulan, amylopectin and glycogen, and in the alpha- and beta-limit dextrins of amylopectin and glycogen

Xylanases
Base reaction: Degrades the linear polysaccharide beta-1,4-xylan into xylose

Lyases
Pectate lyases
Base reaction: Eliminative cleavage of (1->4)-alpha-D-galacturonan to give oligosaccharides with 4-deoxy-alpha-D-galact-4-enuronosyl groups at their non-reducing ends

Alpha-acetolactate decarboxylases
Base reaction: (2S)-2-hydroxy-2-methyl-3-oxobutanoate <=> (3R)-3-hydroxybutan-2-one + CO(2)

Isomerases
Glucose isomerases
Base reaction:  D-glucose 6-phosphate <=> D-fructose 6-phosphate
