title: Biological role of an arginine residue present in a histidine-rich peptide which inhibits hemagglutination of Porphyromonas gingivalis.
abstract: Inhibitory effects of synthetic fragments in histatin 8, having the sequence Lys-Phe-His-Glu-Lys-His-His-Ser-His-Arg-Gly-Tyr, on hemagglutination by Porphyromonas gingivalis 381 were examined. The hemagglutinating activity was reduced much more by the peptide Lys-His-His-Ser-His-Arg-Gly-Tyr than by the peptides Lys-His-His-Ser-His and/or Lys-Phe-His-Glu-Lys. These results suggest that the arginine residue may have an important role in the inhibition of hemagglutination by P. gingivalis.
