WebHistatin 5 (DSHAKRHHGYKRKFHEKHHSHRGY) is one of the basic peptides present in human parotid saliva. More than half of amino acid residues constitute potential ligands for metal ions. Moreover, the HAXXH motif and HXXXH appear twice in the sequence, similarly to proteins which contain zinc or copper, respectively. WebHistatins are a family of at least 12 small, histidine-rich, cationic peptides secreted into human saliva by salivary glands and having antimicrobial activity, especially against fungi such as Candida ( Pollock et al., 1984; Oppenheim et al., 1988 ).

Assessment of the optical density at 620 nm (OD 620) after 48 h of incubation at 30°C showed that C. glabrata was able to grow even in the presence of the highest concentration of histatin 5, while the growth of C. albicans was inhibited by all three histatin con-centrations (Fig. 1). WebFeb 18, 2010 · Histatins are a group of antimicrobial peptides, found in the saliva of man and some higher primates, which possess antifungal properties.
