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 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 کاملSPARQL-DL: SPARQL Query for OWL-DL
There are many query languages (QLs) that can be used to query RDF and OWL ontologies but neither type is satisfactory for querying OWL-DL ontologies. RDF-based QLs (RDQL, SeRQL, SPARQL) are harder to give a semantics w.r.t. OWL-DL and are more powerful than what OWL-DL reasoners can provide. DL-based QLs (DIG ask queries, nRQL) have clear semantics but are not powerful enough in the general ca...
