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

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
