290 g of carrier-bound penicillinacylase according to Example 4, having an enzymatic activity of 2,803 U (NIPAB test) and 138 g of potassium penicillin V are added to 2,000 ml of water and stirred for 9 hours at 38°C. The pH value is kept constant at 7.8 by continuous addition of triethylamine. The mixture is worked up as described in Example 1. Yields of 6-APA 64.3 g (86.1% of theory); purity 97.4%.
