Abstract excerpt

Lactococcus lactis subsp. lactis NCDO 763 (also designated ML3) possesses an X-prolyl dipeptidyl aminopeptidase (X-PDAP; EC 3.4.14.5). X-PDAP mutants were selected by an enzymatic plate assay on the basis of their inability to hydrolyze an L-phenylalanyl-L-proline-beta-naphthylamide substrate. A DNA bank from L. lactis subsp. lactis NCDO 763 was constructed in one of these X-PDAP mutants, and one clone in which...
