Phytase activity in chicken erythrocytes and its control by organic phosphates (glycerate-2,3-P2 and inositol-P5) during avian development.
The activity and basic kinetic constants of phytase were studied in chicken erythrocytes during animal development. The regulatory inhibition of phytase by IHP and 2,3-BPG takes place at key stages of the development. As in mammals, there is a specific control of the levels of organic phosphate involved in the oxygenation process of haemoglobin, during animal development.
