malic enzyme/atrophy

Two adult non-identical twins with autosomal recessive olivopontocerebellar degeneration (OPCA) had markedly deficient adenylate deaminase in skeletal muscle homogenates. Ischemic exercise failed to increase the blood ammonia, while lactate increased normally. Glutamate dehydrogenase and

In vivo, feeding stimulates and starvation inhibits transcription of the malic enzyme gene. In chick-embryo hepatocytes in culture, triiodothyronine (T3) stimulates and glucagon inhibits transcription of this gene. As a first step in the characterization of the involved regulatory mechanisms,

The 'malic' enzyme (ME) gene promoter contains three main regulatory regions. One of these, the direct repeat element (DRE), contains tandem degenerate Sp1-binding sites separated by a 3 bp intervening sequence. We now show that a previously unreported 95 kDa protein, which we have designated DRP-1,

Malic enzyme (ME; NADP(+)-dependent; EC 1 . 1 . 1 . 40) has been postulated to be the rate-limiting step for fatty acid biosynthesis in oleaginous fungi in which the extent of lipid accumulation is below the maximum possible. The genes encoding the isoform of ME involved in fatty acid synthesis were

Aging decreases the quality of seeds and results in agricultural and economic losses. The damage that occurs at the biochemical level can alter the seed physiological status. Although loss of viability has been investigated frequently, little information exist on the molecular and biochemical

Cinnamyl alcohol dehydrogenase (CAD, EC 1.1.1. 195) has been purified to homogeneity from differentiating xylem tissue and developing seeds of loblolly pine (Pinus taeda L.). The enzyme is a dimer with a native molecular weight of 82,000 and a subunit molecular weight of 44,000, and is the only form

Male, Sprague-Dawley rats were weaned prematurely (postnatal day 17) to a starch-based diet. At the age of 182 days, half of the rats were fed for 14 days a diet in which sucrose supplied 40% of the energy. Early weaning led to increases in the activities of hepatic glucose-6-phosphate dehydrogenase

There is an increasing demand for efficient and effective methods to engineer protein variants for industrial applications, structural biology and drug development. We describe a PCR-based strategy that produces multi-site-saturation mutagenic expression library using a circular plasmid carrying the

BACKGROUND Schizophrenia is the most devastating mental illness that causes severe deterioration in social and occupational functioning. This is a pilot study for family-based association analysis of schizophrenia in a Korean population to search candidate genes functionally relevant and

The ovate mutation has frequently been used to study changes in fruit shape but not fruit quality. A deterioration in fruit quality associated with the ovate mutation was discovered in this study. To elucidate how ovate influences the quality of fruit, we performed a proteomics analysis of the
