DNA sequence analysis, expression, distribution, and physiological role of the Xaa-prolyldipeptidyl aminopeptidase gene fromLactobacillus helveticus CNRZ32


Lactobacillus helveticus CNRZ32 possesses and Xaa-prolyldipeptidyl aminopeptidase (PepX), which releases amino-terminal dipeptides from peptides containing proline residues in the penultimate position. The PepX gene, designatedpepX, fromLb. helveticus CNRZ32 was sequenced. Analysis of the sequence identified a putative 2379-bppepX open-reading frame, which… (More)
