The sequence of the amino-terminal region of eleven rat liver ribosomal proteins--S4, S6, S8, L6, L7a, L18, L27, L30, L37a, and L39--was determined. The analysis confirmed the homogeneity of the proteins and suggests that they are unique, since no extensive common sequences were found. The N-terminal regions of the rat liver proteins were compared with(More)
Illumination of intact chloroplasts and treatment of chloroplast stroma with dithiothreitol (DTT) both inactivate glucose-6-phosphate dehydrogenase (G6PDH; EC 1.1.1.49) to less than 10% apparent activity when assayed under standard conditions. Illumination of intact protoplasts and incubation of leaf extract with DTT inactivate about 25-35% of the total(More)
Various properties of purified chloroplast NADP-malate dehydrogenase were analyzed with respect to the redox state of the light/dark-modulated enzyme. The reduced enzyme is less resistant to heat, but the instability can be overcome by the addition of the coenzyme NADPH. Similarly, instability of the reduced NADP-MDH at high pH is alleviated by NADPH. The(More)
