An extracellular phospholipase C was partially purified from Pseudomonas sp. strain KS3.2. The enzyme was composed of an approximately 18-kDa peptide. Maximal enzyme activity was found at pH 7.2 and 50 degrees C. The enzyme retained activity between pH 8 and 9, and 50% activity at about 52 degrees C for 30 min. The enzyme sample showed the highest activity on phosphatidylcholine and low activity toward other phospholipids.
