BACKGROUND: Acute phytic acid intake has been found to decrease iron bioavailability; however, repeated phytic acid consumption leads to iron absorption adaptation. Salivary proline-rich proteins (PRPs) have been shown to inhibit iron chelation to tannins and may mediate similar...

BACKGROUND: Tannins are often cited for antinutritional effects, including chelation of non-heme iron. Despite this, studies exploring non-heme iron bioavailability inhibition with long-term consumption have reported mixed results. Salivary proline-rich proteins (PRPs) may mediate tannin-antinutritional effects on non-heme iron...

Are there phylogenetic differences in salivary tannin-binding proteins between browsers and grazers, and ruminants and hindgut fermenters?.

While feeding, mammalian browsers (primarily eat woody plants) encounter secondary metabolites such as tannins. Browsers may bind these tannins using salivary proteins, whereas mammalian grazers (primarily eat grasses that generally lack tannins) likely would not. Ruminant browsers rechew their...

Direct evaluation of the antioxidant properties of salivary proline-rich proteins.

Journal of clinical biochemistry and nutrition

Komatsu T, Kobayashi K, Morimoto Y, Helmerhorst E, Oppenheim F, Chang-Il Lee M.

J Clin Biochem Nutr. 2020 Sep;67(2):131-136. doi: 10.3164/jcbn.19-75. Epub 2020 Jun 09.

Proline-rich proteins are associated with the formation of an acquired protein layer overlying the tooth enamel surface. Previous studies have described the antioxidant activity of salivary histatin against the hydroxyl radical from Fenton's reaction, acting as the critical reactive...

Salivary proline-rich proteins in mammals: Roles in oral homeostasis and counteracting dietary tannin.

J Chem Ecol. 1995 Jun;21(6):663-91. doi: 10.1007/BF02033455.

We review information on the structure of proline-rich proteins (PRPs), their various functions related to oral homeostasis and dietary tannin, and the structural basis of these functions. Consideration of the multifunctional nature of these salivary proteins helps explain both...

Susceptibility to dental caries and the salivary proline-rich proteins.

Int J Dent. 2011;2011:953412. doi: 10.1155/2011/953412. Epub 2011 Nov 29.

Early childhood caries affects 28% of children aged 2-6 in the US and is not decreasing. There is a well-recognized need to identify susceptible children at birth. Caries-free adults neutralize bacterial acids in dental biofilms better than adults with...
