Inhibition of spinach phosphoribulokinase by DL-glyceraldehyde.
Spinach chloroplast phosphoribulokinase is inhibited by DL-glyceraldehyde. The inhibition is non-competitive with respect to ribulose 5-phosphate (Ki 19mM) and ATP (Ki 20mM). The inhibition is discussed in relation to a previously reported inhibition of CO2 assimilation in intact and envelope-free chloroplasts by DL-glyceraldehyde. It is concluded that the inhibition of phosphoribulokinase is i...
متن کاملTetrose diphosphate, a specific inhibitor of glyceraldehyde 3-phosphate dehydrogenase.
In the course of a study on the osidation of various aldehydes by glyceraldehyde 3-phosphate dehydrogenase (l), it was observed that aged preparations of glycolaldehyde 2-phosphate inhibited strongly the activity of glyceraldehyde Q-phosphate dehydrogenase. Differences in inhibitory potency of several orders of magnitude were noted between various batches. A synthetic preparation, kindly suppli...
متن کاملEffect of DL-glyceraldehyde on mouse neuroblastoma cells in culture.
Neuroblastoma cells had a much higher rate of glycolysis than the Chinese hamster ovary Kl cells, although the former cell type had a longer doubling time (24 hr) than did the latter (12 hr). DL-Glyceraldehyde inhibited the glycolysis in both cell types to the same extent, but it reduced the growth of neuroblastoma cells more markedly than that of Chinese hamster ovary Kl cells. These data indi...
متن کاملInhibition of erythrocyte sickling in vitro by DL-glyceraldehyde.
Concentrations of DL-glyceraldehyde between 5 and 20 mM reduce the sickling of S/S erythrocytes even in the complete absence of oxygen; at 10 mM glyceraldehyde the increase in the number of normal cells ranges from 20 to 40%. The inhibition of sickling was both concentration- and time-dependent and was not reversed by repeated washings with buffer. Incubation of erythrocytes with increasing con...
متن کاملPhotosynthesis by isolated chloroplasts. Inhibition by DL-glyceraldehyde of carbon dioxide assimilation.
Photosynthetic carbon assimilation and associated CO(2)-dependent O(2) evolution by chloroplasts isolated from pea shoots and spinach leaves is almost completely inhibited by 10mm-dl-glyceraldehyde. The inhibitor is without appreciable effect on photosynthetic electron transport, photophosphorylation, the carboxylation of ribulose 1,5-diphosphate or the reduction of 3-phosphoglycerate, but appa...
