Biochem/physiol Actions
Broad-spectrum inhibitor of carboxypeptidases of animal digestive-tract origin, but little or no activity against plant and microbial carboxypeptidases. However, recent results suggest it may play a part in resistance to microbial pathogens by preventing digestion of protein.
Packaging
Package size based on protein content
Unit Definition
One μg of inhibitor protein will inhibit the activity of ≥3 μg of carboxypeptidase A by 50% using hippuryl-L-phenylalanine as substrate at pH 7.5 at 25°C.
Physical form
Lyophilized powder containing traces of sodium citrate and sodium chloride; balance primarily non-protein components.

We have identified, purified, and characterized three subcomplexes of PA700, the 19 S regulatory complex of the 26 S proteasome. These subcomplexes (denoted PS-1, PS-2, and PS-3) collectively account for all subunits present in purified PA700 but contain no overlapping

Lack of experimental human models hinders research on Lassa hemorrhagic fever and the development of treatment strategies. Here, we report the first chip-based model for Lassa hemorrhagic syndrome. The chip features a microvessel interfacing collagen network as a simple mimic
