Purification and characterization of Hb 98-114: A novel hemoglobin-derived antimicrobial peptide from the midgut of Rhipicephalus (Boophilus) microplus

► A new antimicrobial peptide was identified in the tick Ripicephalus microplus. ► This peptide is originated from bovine hemoglobin α-chain amino acids 98-114. ► Synthetic Hb 98-114 permeabilized Candida albicans cells and had fungicidal effect. ► Hb 98-114 has α-helix structure only in the presence of SDS micelles.
