Panel I: Secondary structures of NTH and peptides used in the study (A) The secondary structure of NTH was obtained by extracting residues 19–53 of hACE2 using Maestro from PDB ID 6LZG from https://www.rcsb.org/. (B) The structure of the LL‐37 peptide (2K6O) from https://www.rcsb.org/. (C) The structure of the PACAP‐38 peptide (2D2P) from https://www.rcsb.org/. (D) The structure of the Amylin endocrine hormone (2KB8) from https://www.rcsb.org/. (E) The structure of the GLP‐2 peptide (2L63) from https://www.rcsb.org/. Panel II: Structural alignment of hACE2 NTH with (A) hACE2 NTH, (B) LL‐37, (C) PACAP‐38, (D) Amylin and (E) GLP‐2. The structure of hACE2 NTH is represented in blue color and aligned peptides are shown in red color
