title: Acyl-kallikrein; a delivery system for the kinin-liberating enzyme.
abstract: Glandular kallikrein can be temporarily acylated at the active centre by 4-amidinophenyl benzoates. The time course of reactivation depends on the nature of the acyl group introduced. Benzoyl kallikrein was used as a delivery system for kallikrein in vivo. In rabbits, bolus injection of the acylated enzyme caused a long-lasting drop in blood pressure due to sustained kinin liberation.
