Streptococcus thermophilus CNRZ 302 contains at least three general aminopeptidases able to hydrolyze Phe-beta-naphthylamide substrate. The gene encoding one of these aminopeptidases was cloned from a total DNA library of S. thermophilus CNRZ 302 constructed in Escherichia coli TG1 using

A genomic library of Lactobacillus delbrueckii subsp. lactis DSM7290 DNA fragments from a Sau3A partial digestion in the low-copy-number vector pLG339, was used to screen Escherichia coli for the presence of peptidases. Using the chromogenic substrate leucine-beta-naphthylamide (Leu-NH-Nap) and E.

The puromycin-sensitive aminopeptidase was found to be resistant to proteolysis by trypsin, chymotrypsin, and protease V8 but was cleaved into an N-terminal 60-kDa fragment and a C-terminal 33-kDa fragment by proteinase K. The two proteinase K fragments remain associated and

To elucidate the mechanisms involved in the increase in free amino acids during postmortem storage of meat, a novel aminopeptidase was purified from bovine skeletal muscle by ammonium sulfate fractionation and successive chromatographies such as DEAE-cellulose, Sephacryl S-200, Hydroxyapatite, Phenyl-Sepharose
