Preparation and properties of a liver esterase which hydrolyzes S-acetoacetyldithioloctanoic acid and related thioesters.
The occurrence of thioesterases hydrolyzing thioesters of monothiol coenzymes, e.g. glutathione (l-3) and wenzyme A (P6), is well documented. In the course of experiments on the metabolism of acetoacetyl thioesters (7), it was found that liver enzyme fractions catalyzed the hydrolysis of (f)-S-acetoacetyl6 ,E&dithioloctanoic(dihydrolipoic) acid (Reaction 1) and ( &S-acetyld, Sdithioloctanoic(di...
متن کاملDifferent Stroke Scales; Which Scale or Scales Should Be Use?
Background: There has been considerable development in the clinometric of stroke. But, researcher is concerned that some scales are too generic, inherently and the insight may not be provided. The current study was conducted to determine which scale or scales should be used in stroke survivors. Methods: We selected 67 studies which published between January 2010 and December 2018 from Up to d...
متن کاملThe kinetic mechanism and properties of the cytoplasmic acetoacetyl-coenzyme A thiolase from rat liver.
1. Cytoplasmic acetoacetyl-CoA thiolase was highly purified in good yield from rat liver extracts. 2. Mg(2+) inhibits the rate of acetoacetyl-CoA thiolysis but not the rate of synthesis of acetoacetyl-CoA. Measurement of the velocity of thiolysis at varying Mg(2+) but fixed acetoacetyl-CoA concentrations gave evidence that the keto form of acetoacetyl-CoA is the true substrate. 3. Linear recipr...
