(Synonyms: KerA)

Keratinase (KerA) is an orally active proteolytic enzyme that specifically degrades keratin, and it is mainly secreted by microorganisms such as bacteria, fungi and actinomycetes. Keratinase degrades keratin via reducing disulfide bond cross-links and cleaving peptide bonds, and it can also degrade infectious prion proteins. Keratinase can improve the nutritional bioavailability of keratin-based feed, and it can also be applied in various fields including depilation, proteolytic cleaning, organic fertilizer precursor preparation, cosmetics, bioenergy production, wastewater decolorization, biomolecule extraction, bioremediation, textile biopretreatment and feed processing.

Activité biologique

Description

In Vitro

Keratinase is derived from various bacterial and fungal sources, and exhibits stable activity in keratin degradation, prion inactivation, and leather unhairing^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Keratinase (0.05% (w/w); p.o.; continuous feeding) significantly increases glycine and β-conglycinin hydrolysis in weaned piglets and improves intestinal health parameters^[2].
Versazyme keratinase (p.o.; continuous feeding) improves growth performance, feed efficiency, and intestinal function in broiler chickens^[2].

Dosage:

0.05% (w/w)
Administration:

p.o.; continuous feeding
Result:

Increased glycine hydrolysis from 11.81% to 94.74%.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
