Abstract
Prolyl-dipeptidyl-peptidase activity was detected in cell extracts of 21 lactic acid bacteria [Lactobacillus-sp., Streptococcus-sp.] tested. Using disc electrophoresis and various substrates it was possible to distinguish it from proline iminopeptidase and proline endopeptidase. Generally the activity was high and was greater than that of proline iminopeptidase or proline endopeptidase at neutral pH and at 25.degree. C.This publication has 14 references indexed in Scilit:
