Natural variation within the principal arginine-specific protease gene, prpR1, of Porphyromonas gingivalis.

Oral microbiology and immunology - 1 Oct 1997

Allaker R P, Aduse-Opoku J, Batten J E, Curtis M A

Abstract excerpt

RI, one of the major extracellular arginine-specific proteases of Porphyromonas gingivalis is a heterodimer composed of catalytic (alpha) and adhesin (beta) chains, encoded by the gene prpR1. The distribution of prpR1 and its variation within 43 isolates of P. gingivalis was determined. Chromosomal DNA was digested with Sma I and probed with a 32P-labeled DNA fragment from within the coding region for the alpha...
