title: Purification and characterization of a dipeptidase from Lactobacillus sake.
abstract: A dipeptidase was purified from cell extracts of Lactobacillus sake. This compound was a monomer having a molecular weight of 50,000 and a pI of 4.7 and exhibited broad specificity against all dipeptides except those with proline or glycine at the N terminus. The enzyme was inhibited by EDTA or 1,10-phenanthroline but could be reactivated with CoCl2 and MnCl2.
