Metalloendopeptidases EC 3.4.24.15 and EC 3.4.24.16: potential roles in vascular physiology
2001
The zinc metalloendopeptidases EC 3.4.24.15 (EP 24.15) and EC 3.4.24.16 (EP 24.16) are closely related ubiquitous enzymes, which have well-defined in vitro activities in generation and degradation of a range of specific peptide targets. Despite this, little is known regarding their roles in whole animal physiology. One of the peptides degraded by these enzymes in vitro is bradykinin, a mediator with potent effects on the vasculature at both systemic and local levels. This review summarises the work that has examined the role of EP 24.15/24.16 in regulation of the vascular effects of bradykinin in vivo. This work was made possible by the development of a specific stable inhibitor of these enzymes, JA-2. Use of this inhibitor has shown that EP 24.15/24.16 are capable of regulating responses induced by exogenous bradykinin. This effect was observed at a systemic level with an increase in the hypotensive effect of intravenous bradykinin. Further work is required to determine whether these enzymes also regulate bradykinin produced endogenously.
