Aspergillopepsin I

(Synonyms: Aspergillus acid protease)

Kundenbewertung

Based on 1 Customer Validation

Aspergillopepsin I (Aspergillus acid protease) is a metal-containing aspartic protease that catalyzes the hydrolysis of peptide bonds in soybean 7S globulin, soybean 11S globulin and various proteins, with broad specificity. Aspergillopepsin I is intended for use in wine production, where it hydrolyzes haze-forming proteins into small peptides to prevent turbidity during storage. Aspergillopepsin I can be used in studies related to soybean protein hydrolysis and wine production.

Biologische Aktivität

Beschreibung

In Vitro

Aspergillopepsin I can hydrolyze defatted soybean meal, increasing the contents of soluble protein, amino nitrogen, free amino acids, and small molecular peptides with molecular weight <3 kDa in the hydrolysate^[1].
Aspergillopepsin I exhibits the highest relative activity at pH 3.5 and 35-40°C. It maintains pH stability within the range of pH 3.0-3.5, thermal stability within 20-50°C, and possesses salt tolerance. Its activity is promoted by K⁺ and Zn²⁺, and slightly inhibited by Mg²⁺, Cu²⁺, Co²⁺ and Fe²⁺^[1].
Aspergillopepsin I does not induce gene mutations in bacterial strains, nor does it cause chromosomal aberrations in mammalian cells^[2].

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

In Vivo

The no-observed-adverse-effect level (NOAEL) of Aspergillopepsin I for 90-day oral administration in rats is 919 mg TOS/kg bw/day; its amino acid sequence matches known respiratory allergens, presenting a low but non-excludable risk of dietary allergic sensitization^[2].

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.
