The '''<scene name='10/1083732/Peptidase_domain/1'>Peptidase Domain</scene>''' is responsible for the enzymatic activity of ACE2. This domain can be divided in two subdomains: <scene name='10/1083732/Subdominio_1_nterm/1'>Subdomain I</scene> (residues 19–400) and <scene name='10/1083732/Subdominio_2_cterm/1'>Subdomain II</scene> (residues 401–615). Together, they form a substrate-binding cleft, where is located the '''<scene name='10/1083732/Sitio_zinco_com_residuos/1'>catalytic site</scene>''', denominated '''HEXXH+E zinc-binding motif'''. Within this site, a '''{{Font color|lime|zinc-ion}}''' is associated with the residues '''His374''', '''His378''', and '''Glu402''', which are going to perform a nucleophilic attack on the peptide bond of the substrate, leading to its cleavage. '''<scene name='10/1083732/Peptidase_domain_hydrofobic/2'>Hydrophobic portions</scene>''' within each subdomain, composed mainly of nonpolar residues provide tertiary structural stability, maintaining the correct spatial arrangement of catalytic residues. In the animation, we can observe a concentration of the '''{{Font color|gray|hydrophobic residues}}''' towards the center of the molecule, while the '''{{Font color|orchid|polar}}''' ones are towards the outside part of the molecule.

The <scene name='10/1083732/Transmembrane_domain/1'>Transmembrane Domain</scene> is composed of a '''{{Font color|red|single alpha helix}}''', made of a majority of <scene name='10/1083732/Transmembrane_domain_hydrop/1'>hydrophobic residues</scene> (in '''{{Font color|gray|gray}}'''). This characteristic allows ACE2 to be anchored in the plasma membrane, due to its hydrophobic nature.
