Mechanism of Ligand Recognition by Human ACE2 Receptor.

ABSTRACT: Angiotensin converting enzyme 2 (ACE2) plays a key role in renin-angiotensin system regulation and amino acid homeostasis. Human ACE2 acts as the receptor for severe acute respiratory syndrome coronaviruses SARS-CoV and SARS-CoV-2. ACE2 is also widely expressed in epithelial cells of the lungs, heart, kidney, and pancreas. It is considered an important drug target for treating SARS-CoV-2 as well as pulmonary diseases, heart failure, hypertension, renal diseases, and diabetes. Despite the critical importance, the mechanism of ligand binding to the human ACE2 receptor remains unknown. Here, we have addressed this challenge through all-atom simulations using a novel ligand Gaussian accelerated molecular dynamics (LiGaMD) method. Microsecond time scale LiGaMD simulations have unprecedentedly c
