Description

Unit Definition

1 U corresponds to the amount of inhibitor which reduces the trypsin activity by 1 BAEE-U. (1 BAEE-U is the amount of enzyme which increases the absorbance at 253 nm by 0.001 per minute at pH 7.6 and 25 °C; BAEE, Cat. No. 12880, as substrate).

Biochem/physiol Actions

A potent inhibitor of Hageman Factor (clotting factor XII); it also inhibits trypsin, but not kallikrein. Inhibited growth of all nine plant pathogenic fungi studied; may be involved in host resistance to fungal pathogens.
