Summary

By use of di- or tripeptides as substrates, LAP 1 and LAP 2, 2 fractions fromAspergillus oryzae hydrolyze oligopeptides that possess leucine as N-terminal amino acid. LAP 1 fraction also hydrolyzes the histidyl bond. Both fractions have no activity towards peptides as glutathion, gly-pro-ala; they have low or no activity towards tyrosyl and tryptophanyl bond.
