A relatively simple procedure was devised for the purification of Adenosine Triphosphate Creatine Phosphotranseferase(E. C. 2. 7. 3. 2.) from duck breast muscle extracts. The enzyme was purified and yield of close to 25%. The specific enzyme activity, thiol group and amino acids were determined.
The results are as follows:
1. Adenosine Triphosphate Creatine Phosphotranseferase from (luck breast muscle extract has a specific activity of 76.32 units/§·.
2. The thiol group of the duck breast muscle creatine kinase was 6.2 §ß/M. of enzyme.
3. All most essential amino acids are contained in this enzyme.
