Pilot study on binding of bovine salivary proteins to grit silicates and plant phytoliths
MAU, Marcus; KAISER, Thomas M. & SÜDEKUM, Karl-Heinz
Abstract
Mostly fed with grass in fresh or conserved form, cattle and other livestock have to cope with silicate defence bodies from
plants (phytoliths) and environmental silicates (grit), which abrade tooth enamel and could additionally interact with various salivary
proteins. To detect potential candidates for silicate-binding proteins, bovine whole saliva was incubated with grass-derived phytoliths
and silicates. Interactions of salivary proteins with pulverized bovine dental enamel and dentine were additionally analysed. After
intense washing, the powder fractions were loaded onto 1D-polyacrylamide gels, most prominent adhesive protein bands were cut
out and proteins were identified by mass spectrometry within three independent replicates. All materials were mainly bound by
bovine odorant-binding protein, bovine salivary protein 30×103 and carbonic anhydrase VI. The phytolith/silicate fraction showed
additional stronger interaction with haemoglobin β and lactoperoxidase. Conceivably, the binding of these proteins to the surfaces
may contribute to biological processes occurring on them.
