HBA (111–142)

This 32-amino acid C-terminal fragment of alpha-hemoglobin (HBA 111-142) exhibits broad-spectrum antibacterial activity against ESKAPE pathogens and inhibits viruses including measles and herpesviruses. It also self-assembles into amyloid fibrils, making it a valuable tool for researching host defense peptides, amyloidogenesis, and antiviral mechanisms in vitro.
