Failure to Maintain Acetate Homeostasis by Acetate-Activating Enzymes Impacts Plant Development

The acetate activating enzyme of beef heart.

Assay System-The assay system, previously described (1, 6, 7), is based on the conversion of acetyl CoA to citrate in the presence of malic dehydrogenase and condensing enzyme. The oxalacetate necessary for the condensation reaction is generated by the oxidation of malate in the presence of DPN, and the rate of DPN reduction is proportional to the concentration of AAE present, within the limits...

Anaphylaxis to Glatiramer Acetate

Glatiramer acetate (Copaxone, Teva Pharma) and interferon beta are the two only disease-modifying therapies for multiple sclerosis. Glatiramer acetate is known for frequently simulating mild, anaphylactoid reactions while true, IgEmediated allergic reactions have been hardly reported so far. Herein, we report two females suffering from multiple sclerosis who experienced rapidly aggravating hype...

The acetate activating enzyme system of heart muscle.

Nachmansohn and Machado (1) discovered a soluble enzyme system in extracts of brain tissue which catalyzed the formation of active acetate in the presence of ATPI and CoA. Active acetate was detected by the acetylation of choline. Later Lipmann (2, 3) reported an enzyme system in extracts of pigeon liver which catalyzed the CoA and ATP-dependent acetylation of sulfanilamide by acetate. The iden...

Clostebol acetate

The title compound, C(21)H(29)ClO(3) [systematic name (8R,9S,10R,13S,14S,17S)-4-chloro-3-oxoandrost-4-en-17β-yl acetate], is a 4-chloro derivative of testosterone, used as an anabolic androgenic agent or applied topically in ophthalmological and dermatological treatments. The absolute configurations at positions 8, 9, 10, 13, 14 and 17 were established by refinement of the Flack parameter as R,...
