Collagen Degrading Units (CDU) (Mandl Units) |
One CDU catalyzes the hydrolysis of 1 µmole of L-leucine equivalents from collagen in 5 hours at 37°C, pH 7.4 |
1 Wünsch unit = ~1000 CDU
1 Wünsch unit = ~3.9 FALGPA units
1 Wünsch unit = ~10 HPU |
| FALGPA unit |
One FALGPA Unit catalyzes the hydrolysis of 1
µmole of N-(3-[2-furyl]-acryloyl)- L- leucylglycyl- Lprolyl-L-alanine (FALGPA) per minute at 25°C, pH 7.5 |
Wünsch units
(PZ Units) |
One PZ unit catalyzes the hydrolysis of 1 µmole 4-phenylazobenzyloxycarbonyl- L-prolyl- Lleucyl-glycyl-L-prolyl-D-arginine per minute at 25 °C, pH 7.1 |
| Clostridiopeptidase A “HP Units” (HPU) |
One HPU catalyzes the hydrolysis of 1 µmole N-carbobenzyloxy- glycyl-L- prolyl-lycylglycyl-L-prolyl-L-alanine per minute at 37°C |
