摘要
Purified monkey chymase cleaved the Tyr(31)-Gly(32) bond of big-endothelin-1 and big-endothelin-2 to yield endothelin-1-(1-31) and endothelin-2-(1-31), respectively. In the isolated monkey trachea, endothelin-1-(1-31) and endothelin-2-(1-31), as well as big-endothelin-1 and big-endothelin-2, induced contractile responses. Chymostatin, which inhibits chymase, suppressed the contractile response induced by big-endothelin-2 to 16.6% but not the responses induced by big-endothelin-l, endothelin-1-(1-31) and endothelin-2-(1-31). These results suggest that the contractile response of big-endothelin-2 is predominantly dependent on the conversion of big-endothelin-2 to endothelin-2-(1-31) by chymase.
