Cloning of a Streptococcus mutans glucosyltransferase gene coding for insoluble glucan synthesis
Results indicate that the gtfB gene codes for a GTF involved in insoluble glucan synthesis in strain GS-5, and evidence for the existence of a distinct gene sharing partial homology with gTFB was obtained.
Glycylprolyl Dipeptidylaminopeptidase from Bacteroides gingivalis
Dipeptidyl aminopeptidase activity was found in the culture medium of Bacteroides gingivalis 381 and the purified enzyme specifically cleaved glycylprolyl dipeptide from partially digested type I collagen.
A 35-kDa co-aggregation factor is a hemin binding protein in Porphyromonas gingivalis.
Stimulation of interleukin-6 production of periodontal ligament cells by Porphyromonas endodontalis lipopolysaccharide.
Results suggest that stimulation of the IL-6 release of PDL cells by P. endodontalis LPS may have a role in the progression of inflammation and alveolar bone resorption in periodontal and periapical diseases.
Sequence analysis of the Porphyromonas gingivalis dipeptidyl peptidase IV gene.
Isolation and characterization of the sucrose 6-phosphate hydrolase gene from Streptococcus mutans
Results suggest that processing of the hydrolase occurs in S. mutans GS-5, and the relative position of the gene in the insert has been determined after Tn5 mutagenesis and deletion analysis.
A sensitive method for detecting Porphyromonas gingivalis by polymerase chain reaction and its possible clinical application.
The PCR assay established in this study can be a powerful tool to detect P. gingivalis in periodontal pockets and monitor the colonization and/or recolonization of P.g. at the very early phase.
