Modulating the potency of an activator in a yeast in vitro transcription system.
The intrinsic stimulatory potential or potency of a eukaryotic gene activator is controlled by the interaction between the activation domain and the transcriptional machinery. To further understandExpand

Human liver long-chain 3-hydroxyacyl-coenzyme A dehydrogenase is a multifunctional membrane-bound beta-oxidation enzyme of mitochondria.
We have purified to homogeneity the long-chain specific 3-hydroxyacyl-CoA dehydrogenase from mitochondrial membranes of human infant liver. The enzyme is composed of non-identical subunits of 71 kDaExpand

The synthesis and characterisation of 2-methylacetoacetyl coenzyme A and its use in the identification of the site of the defect in 2-methylacetoacetic and 2-methyl-3-hydroxybutyric aciduria.
(1) 2-Methylacetoacetyl coenzyme A was prepared, purified by ion exchange chromatography as judged by TLC and HPLC and a number of its properties characterised. (2) An assay of 3-oxothiolase inExpand

3-Ketoacyl-CoA thiolases of mammalian tissues.
Publisher Summary This chapter discusses the determination of 3-ketoacyl-CoA thiolases of mammalian tissues. 3-Ketoacyl-CoA thiolase activity is determined by following the stimulation ofExpand

Mitochondrial Fatty Acid β-Oxidation in the Human Eye and Brain: Implications for the Retinopathy of Long-Chain 3-Hydroxyacyl-CoA Dehydrogenase Deficiency
The retinal pigment epithelium (RPE) and the choriocapillaris are affected early in the retinopathy associated with long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency. RPE in cultureExpand

Urinary excretion of 2-methylacetoacetate, 2-methyl-3-hydroxybutyrate and tiglylglycine after isoleucine loading in the diagnosis of 2-methylacetoacetyl-CoA thiolase deficiency
SummaryThe concentrations of 2-methylacetoacetate, 2-methyl-3-hydroxybutyrate and tiglylglycine were determined by gas chromatography-mass spectrometry in urine collected before and for 8 h afterExpand

Effects of hypothyroidism and high-fat feeding on mRNA concentrations for the low-density-lipoprotein receptor and on acyl-CoA:cholesterol acyltransferase activities in rat liver.
1. Induction of hypothyroidism in rats by feeding propylthiouracil (PTU) significantly increased serum cholesterol concentrations, and the effect was more pronounced for cholesterol in low-densityExpand

The kinetic mechanism of 3-hydroxy-3-methylglutaryl-coenzyme A synthase from baker's yeast.
1. The effect of independent variation of both acetyl-CoA and acetoacetyl-CoA on the initial velocity at pH8.0 and pH8.9 gives results compatible with a sequential mechanism involving a modifiedExpand
