title: Cloning of the gene encoding a glycylprolyl aminopeptidase from Porphyromonas gingivalis.
abstract: A genomic library of Porphyromonas gingivalis 381 was constructed in the cosmid vector pHC79. A clone, pSN1, was identified by the expression of glycylprolyl-naphthylamide hydrolysing activity. The DNA insert contained within the cosmid pSN1 was subcloned into the plasmid vector pBR328 to create the recombinant plasmid pSN11 containing a 2.9 kb EcoRV insert. An Escherichia coli transformant containing pSN11 produced a protein having a molecular weight of 75 kDa. Southern-blot hybridization revealed that the 2.9 kb EcoRV DNA hybridized with an identical sized Eco RV DNA fragment in the chromosomal DNA of P. gingivalis 381.
