Application
Protease from Aspergillus saitoi has been used in a study to assess sequence coverage and resolution in hydrogen exchange of large proteins. It has also been used in a study to investigate the conversion of soybean curd isoflavone glycosides to their aglycones through β-glucosidase..
Biochem/physiol Actions
Protease from Aspergillus saitoi was shown to also function as a β-glucosidase.
Other Notes
One unit will hydrolyze hemoglobin to produce color equivalent to 1.0 μmole (181 μg) of tyrosine per min at pH 2.8 at 37 °C (color by Folin-Ciocalteu reagent).

This review covers the unique catalytic and molecular properties of three proteolytic enzymes and a glycosidase from Aspergillus. An aspartic proteinase from A. saitoi, aspergillopepsin I (EC 3.4.23.18), favors hydrophobic amino acids at P1 and P'1 like gastric pepsin. However

The combination of hydrogen exchange and mass spectrometry has been widely used in structural biology, providing views on protein structure and protein dynamics. One of the constraints is to use proteases working at low pH and low temperature to limit

For the construction of an overexpression system of the intracellular 1,2-alpha-mannosidase (EC 3.2.1.113) gene (msdS) from Aspergillus saitoi (now designated Aspergillus phoenicis), the N-terminal signal sequence of the gene was replaced with that of the aspergillopepsin I (EC 3.4.23.18) gene

An Aspergillus saitoi protease preparation, Molsin, was found to contain beta-glucosidase as well as protease activities. Application of Molsin to soybean curd improved its functionality by converting the contained isoflavone glycosides to their aglycones through beta-glucosidase, and also modified the
