Abstract

1. Biochemical properties of delta 1-pyrroline-5-carboxylate reductase from d. melanogaster have been investigated. 2. The enzyme is stable below 4 degrees C. 3. the pH optimum of the enzyme is 5.7. It is rapidly inactivated below pH 5.4. 4. The Km values for NADPH and delta 1-pyrroline-5-carboxylate are 1.6 x 10-5 and 2.5 x 10-6 M, respectively. 5. the estimated molecular weight of the enzyme is 225,000. 6. the enzyme is weakly inhibited by L-proline (Ki = 0.12 M).
