General description

Exhibits both proteolytic and lipolytic activities.
Proteases are proteolytic enzymes that digests the proteins. It is classified into acidic, neutral and alkaline proteases based on their pH optimum. Proteases finds its applications in textile industries, laundry and healthcare. It is also being used in food processing industries such as baking and brewing. Rhizopus chinensis is the key species in the production of aspartate proteinase.
Stable in the acid range of pH 3-5. pH Optimum is 3.0.

Application

Protease from Rhizopus sp. has been used in the enzyme treatment of planted and nonplanted scots pine seedlings.
Protease from Rhizopus spp. Has been used in a study to assess the amino acid sequences near the amino termini using automated Edman degradation. It has also been used in a study to investigate inactivation of the enzyme by reaction with diazoacetyl-DL-norleucine methyl ester in the presence of cupric acetate.

Biochem/physiol Actions

Protease from Rhizopus chinensis can be inhibited by pepstatin.

Unit Definition

One unit will hydrolyze casein to produce color equivalent to 1.0 μmole (181 μg) of tyrosine per min at pH 3.0 at 37 °C (color by Folin-Ciocalteu reagent), unless otherwise indicated.

Physical form

Supplied as a powder containing dextrin as a stabilizer

Four derivatives of pepstatin, each of which contains the unusual amino acid 4-amino-3-hydroxy-6-methylheptanoic acid (statine) have been prepared. All four are porcine pepsin inhibitors. Both N-acetylstatine and N-acetyl-alanyl-statine are competitive inhibitors for pepsin with Ki values of 1.2 X 10(-4)
