Biochem/physiol Actions

A human salivary peptide that inhibits the protease of Bacteroides gingivalis, as well as clostripain.
The antifungal (Candida, Leishmania) activity of histatin 5 involves penetration of the microbial cell, localization in the mitochondria, and inhibition of F1-F0 ATPase, with rapid depletion of ATP.

We examined the effect of histatin 5 from human parotid saliva on various proteases. Histatin 5 strongly inhibited a trypsin-like protease produced by Bacteroides gingivalis with an IC50 value of 55 nM. Clostripain was also inhibited (IC50 = 800 nM).

Biochemical and biophysical research communications, 250(2), 474-478 (1998-10-01)
The salivary peptide histatin 5 has been reported to be an inhibitor of the Arg- and Lys-specific proteinases of Porphyromonas gingivalis, an oral pathogen associated with periodontitis. In this study a purified P. gingivalis proteinase preparation consisting of a complex

Salivary histatins are potent in vitro antifungal proteins and have promise as therapeutic agents against oral candidiasis. We performed pharmacological studies directed at understanding the biochemical basis of Hst 5 candidacidal activity. Three inhibitors of mitochondrial metabolism: carbonyl cyanide p-chlorophenylhydrazone
