The Lactobacillus helveticus CNRZ32 gene encoding a di-/tri- pepidase with prolinase activity (pepPN) was sequenced. An open reading frame of 912 base pairs was identified corresponding to a peptide with a molecular mass of 35.04 kDa. Southern hybridization indicated that the gene sequence is well conserved in strains of lactobacilli and pediococci.
