Nucleotide sequence of gene PBI encoding a protein homologous to salivary proline-rich protein P-B.
The nucleotide sequence of gene PBI, the putative translational product of which is homologous to salivary proline-rich protein P-B, has been determined. PBI is 6.4 kb long and contains 3 exons. PBI appears to code for the precursor of a proline-rich protein which we have designated P-B1. The P-B1 precursor is composed of 134 amino acid residues including 22 residues of signal sequence, 23 resi...
متن کاملMultiple interactions between polyphenols and a salivary proline-rich protein repeat result in complexation and precipitation.
Polyphenols (tannins) in the diet not only precipitate oral proteins, producing an astringent sensation, but also interact with dietary proteins and digestive enzymes in the gut, resulting in a variety of antinutritive and toxic effects. Salivary proline-rich proteins (PRPs), which are secreted into the oral cavity, form complexes with and precipitate dietary polyphenols, and thus, they constit...
متن کاملSalivary proline-rich protein genes on chromosome 8 of mouse.
Endonuclease restriction (Hind III) fragments of DNA from Chinese hamster X mouse somatic cell hybrids hybridized with proline-rich protein complementary DNA clones only when the DNA was isolated from cells containing mouse chromosome 8, or a fragment of chromosome 8. The evidence suggests that proline-rich protein genes are located at the proximal portion of chromosome 8 toward the centromere.
متن کاملA conformational study of a glutamine- and proline-rich cereal seed protein, C hordein.
A combination of c.d. spectroscopy and computer prediction is used to show that C hordein has an unusual secondary structure with an absence of alpha-helix and beta-sheet, but the presence of regularly repeated beta-turns. This is associated with a repetitive primary structure based mainly on blocks of eight residues. Similar spectral changes occurred when the protein was heated from 6 to 86 de...
متن کاملSalivary proline-rich protein may reduce tannin-iron chelation: a systematic narrative review
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 bioavailability. AIM To review evidence regarding biochemical bind...
