| Abstract: | The effect of thermal acclimatization on the incorporation of [3H]-l-leucine into muscular acid-soluble amino acids, soluble proteins and into the lactate dehydrogenase was studied in the shrimp Palaemon serratus As far as protein synthesis is concerned, a period of time of 10 to 15 days is required for the achievement of the process. During acclimatization to 10° or 20° three periods can be distinguished. During the first 3–4 days the temperature increment exert a direct decreasing or increasing effect on the protein synthesis. The system then tends to reach a new equilibrium respectively below or above the initial level: the synthesis mechanisms were able to partially compensate the effect of thermal variations. The synthesis of LDH follows the general pattern of incorporation of the labelled precursor into the macromolecules |
