Labyrinthula strains isolated from coastal regions of Kagoshima Prefecture and the Philippines exhibited algicidal activity for diatom living cells, bacteriolytic activity for Vibrio dead cells, and hydrolytic activity for high molecular substances such as starch and casein. Cell extract from Labyrinthula strains found to possess leucine aminopeptidase(LAPase). Optimal temperature and pH of the crude enzyme were 30C and 8.0, respectively and it was　stable up　to　55C. LAPase　was　inhibited with Ag^+, Zn^{2+}, Hg^{2+} and EDTA, and activated with Co^{2+}.
