Structure of human ACE gives new insights into inhibitor binding and design.

摘要

Angiotensin-converting enzyme (ACE) is a primary target of drugs used for controlling hypertension. A new X-ray crystallographic structure of the key catalytic domain of ACE provides detailed information about the structure of its active site, located in a deep channel, and its interactions with an inhibitor. Such information might facilitate the rational design of ACE inhibitors that are more potent and more selective and therefore of clinical use.
