Abstract
This study suggests degradation of salivary acidic proline-rich proteins (PRPs) into potential innate-immunity-like peptides by oral Streptococcus and Actinomyces species. PRP degradation paralleled cleavage of Pro-containing substrates. PRP degradation by S. gordonii strain SK12 instantly released a Pyr(1)-Pro(104)Pro(105) and a Gly(111)-Pro(149)Gln(150) peptide together with a presumed Arg(106)Gly(107)Arg(108)Pro(109)Gln(110) pentapeptide. The synthetic Arg(106)Gly(107)Arg(108)Pro(109)Gln(110) peptide desorbed bound bacteria and counteracted sucrose-induced decrease of dental plaque pH in vitro.Entities:
