Abstract

The withdrawal of pyridoxine from the diet of male weading rats did not appear to affect the liver mitochondrial L-aspartate : 2-oxoglutarate amhotransferase, but the ismnzymes in the liver supematant and in the erythrocyte showed gradual lowering of activity. The liver kalanine : Zoxoglutarate aminatransferase activity (mostly residing in the supernatant) showed a sharp and immediate decline, and that of the erythrocyte exhibited a more gradual decline with the progress of deficiency. The liver supernatant and erythrocyte aspartate aminotransferases of the deficient animals showed a marked recowry with subcutaneous injection of pyridoxine and in vitro addition of pyridoxal-5-phosphate to the enzyme system. The data emphasize the sensitivity of the supernatant and erythrocyte aspartate aminotransfemses in reflecting the pyridoxine nutritional state of the rat.
