Inhibition of citrate synthase by oleoyl-CoA: a regulatory phenomenon.
Fatty acyl-CoAs are good detergents (dritical micelle concentrations = 3-4 muM) and can inhibit a number of enzymes, including some involved in fatty acid biosynthesis. The regulatory significance of fatty acyl-CoAs as negative effectors has been questioned largely because of the difficulties in distinguishing possible nonspecific detergent effects from more specific regulatory interactions wit...
متن کاملMechanism of the Propionyl Carboxylase Reaction
A study of the exchange reactions between adenosine triphosphate and either radioactive inorganic phosphate, or adenosine diphosphate (l), catalyzed by propionyl carboxylase, showed that inorganic phosphate was required for adenosine triphosphate-adenosine diphosphate exchange and, conversely, adenosine diphosphate was required for adenosine triphosphateinorganic phosphate exchange. A requireme...
متن کاملN-lysine propionylation controls the activity of propionyl-CoA synthetase.
Reversible protein acetylation is a ubiquitous means for the rapid control of diverse cellular processes. Acetyltransferase enzymes transfer the acetyl group from acetyl-CoA to lysine residues, while deacetylase enzymes catalyze removal of the acetyl group by hydrolysis or by an NAD(+)-dependent reaction. Propionyl-coenzyme A (CoA), like acetyl-CoA, is a high energy product of fatty acid metabo...
متن کاملCloning and characterisation of the gene encoding 3-hydroxy-3-methylglutaryl-CoA synthase in Tripterygium wilfordii.
Tripterygium wilfordii is a traditional Chinese medical plant used to treat rheumatoid arthritis and cancer. The main bioactive compounds of the plant are diterpenoids and triterpenoids. 3-Hydroxy-3-methylglutaryl-CoA synthase (HMGS) catalyses the reaction of acetoacetyl-CoA to 3-hydroxy-3-methylglutaryl-CoA, which is the first committed enzyme in the mevalonate (MVA) pathway. The sequence info...
متن کاملAssessing the reversibility of the anaplerotic reactions of the propionyl-CoA pathway in heart and liver.
While a number of studies underline the importance of anaplerotic pathways for hepatic biosynthetic functions and cardiac contractile activity, much remains to be learned about the sites and regulation of anaplerosis in these tissues. As part of a study on the regulation of anaplerosis from propionyl-CoA precursors in rat livers and hearts, we investigated the degree of reversibility of the rea...
