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. [1]
Structure
Renin belongs in a family called aspartic proteases which use an aspartate residue for the catalysis of their peptide substrate. X-ray diffraction experiments has shown there is a striking similarity among the structures of aspartyl proteases. [2] Renin consists of two homologous lobes each containing an aspartic acid. Between the lobes is the active site, which is catalyzed by the aspartic acid residues, a characteristic trait of all aspartate proteases. [1] Renin in its full mature form has a mass of 37 kDa and contains 340 amino acids.[3]
Biochemistry
Renin is an aspartyl protease. [4]

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. [5]
