[Effect of hypoxia on activity of glucose-6-phosphate dehydrogenase in red mullet and sea scorpion tissues].

90 min hypoxia (50% initial saturation) does not change the level of glucose-6-phosphate dehydrogenase activity in liver and brain of the red mullet. It is shown, that existence of the sea scorpion in environmental with low oxygen concentration (15% initial saturation) results in the increasing in this enzyme activity for 68% (p < 0.05). The rise of h values for NADP in 1.2-1.4 times and substrate-binding ability in 1.5-3 times are found for glucose-6-phosphate dehydrogenase from sea scorpion liver under hypoxia.
