Introduction

Renin (pronounced /ˈriːnɨn/ REE-nin) is also known as angiotensinogenase, a monospecific enzyme that participates in the body's renin-angiotensin system (RAS). Renin is responsible for catalyzing the rate-limiting step in the synthesis of angiotensin II. Once renin and pro-renin bind to the pro-renin receptor, there is an increased enzymatic activity and additional physiological effects.

Structure

Renin belongs in the family called aspartic proteases because they use an aspartate residue for catalysis of their peptide substrate.

Biochemistry

Renin is an aspartyl protease.

Function

Renin plays a key role in the Renin-Angiotension sysmtem (RAS). This system is responsible for the control of blood pressure and salt balances in mammals.
