Beta-glucuronidases are members of the glycosidase family of enzymes that catalyse breakdown of complex carbohydrates. Human β-glucuronidase is a type of glucuronidase that catalyses hydrolysis of β-D-glucuronic acid residues from the non-reducing end of mucopolysaccharides, such as heparan sulfate. In human gut β-glucuronidase converts conjugated bilirubin to the unconjugated form for reabsorption.

HRP is a plant glycohemoprotein belongs to the ferroprotoporphyrin group of peroxidases. It is used in biochemistry applications such as western blots, ELISA and Immunohistochemistry. It is used to amplify a weak signal and increase detectability of a target molecule, such as a protein. HRP labeled immunoglobulins are used as probes for the demonstration of tissue antigens and in enzyme immunoassay (EIA) systems for determination of soluble and insoluble antigens.

Bromelain is a glycoprotein which is a highly active thiol proteinase (non-specific cysteine protease), which splits glycine esters but not lysine esters; it is also a protein-digesting and milk-clotting enzyme. Substrates susceptible to bromelain include all of the common protein materials such as gelatin, casein, gluten, collagen, elastin, globulins an muscle fiber protein. It is a cysteine endopeptidase with broad specificity for cleavage of proteins. It may be from a stem or piece of fruit.
