1. Effect of Cottonseed Meal Fermented with Yeast on the Lipid-related Gene Expression in Broiler Chickens
ABSTRACT Fermented cottonseed meal (FCSM) is widely used in poultry diets in China. This study was conducted to investigate the effect of FCSM on lipid-related gene expression in broilers. Initially, 180 broiler chickens (21-days-old, equal number of males and females) were randomly divided into three groups, with six pens per group and 10 birds per pen. The

2. Activation of AMPK/Acetyl-Coa carboxylase in the hypothalamus of cold exposed rats / Ativação da via de sinalização AMPK/Acetil-CoA carboxilase no hipotalamo de ratos expostos a baixa temperatura
The exposure of homeothermic animals to a cold environment leads to a powerful activation of orexigenic signalling which is accompanied by molecular and functional resistance to insulin-induced inhibition of feeding. Recent evidence suggests that AMPK participates in nutrient-dependent control of satiety and adiposity. The objective of the present study was

3. Regulation of acetyl-coA carboxylase: properties of coA activation of acetyl-coA carboxylase.
Acetyl-CoA carboxylase [acetyl-CoA:carbon-dioxide ligase (ADP-forming), EC 6.4.1.2] is activated by physiological concentrations of CoA. The CoA concentration dependency of this activation is sigmoidal; below 60 microM there is little or no activation, but the activation observed between 60 and 120 microM indicates that small changes in the concentration of

4. ACETYL COA CARBOXYLASE, II. DEMONSTRATION OF BIOTIN-PROTEIN AND BIOTIN CARBOXYLASE SUBUNITS*
Previous work has shown that Escherichia coli acetyl CoA carboxylase is composed of two dissimilar protein components, Ea which contains covalently bound biotin and forms Ea-CO2-from HCO3- and ATP, and Eb which is involved in the transfer of the carboxyl group from Ea-CO2- to acetyl CoA, forming malonyl CoA. Ea has been dissociated into two subunits at pH 9.

5. Acetyl CoA Carboxylase: The Purified Transcarboxylase Component
Acetyl CoA carboxylase of Escherichia coli has been resolved into three functionally dissimilar proteins: (1) biotin-carboxyl carrier protein (BCCP); (2) a biotin carboxylase component that catalyzes the Mn-ATP-dependent carboxylation of BCCP to form CO2--BCCP; and (3) a transcarboxylase component that catalyzes the transfer of the carboxyl group from CO2--B

6. The Carboxyl Transferase Component of Acetyl CoA Carboxylase: Structural Evidence for Intersubunit Translocation of the Biotin Prosthetic Group
An essential protein component of acetyl CoA carboxylase, isolated and extensively purified from cell-free extracts of Escherichia coli, has been identified as malonyl CoA: d-biotin carboxyl transferase. This enzyme, which does not contain covalently-bound biotin, catalyzes carboxyl transfer from malonyl CoA to free d-biotin, a model reaction for the second

8. Enzymatic Carboxylation of Biotin: Molecular and Catalytic Properties of a Component Enzyme of Acetyl CoA Carboxylase*
The biotin carboxylase component of acetyl CoA carboxylase has been purified approximately 2000 times from Escherichia coli. This protein, which catalyzes the carboxylation of free d-biotin, is free of the biotin-containing carboxyl carrier protein, is homogeneous by polyacrylamide gel electrophoresis and analytical ultracentrifugation, and has been crystall

9. Molecular cloning, characterization, and elicitation of acetyl-CoA carboxylase from alfalfa.
Acetyl-CoA carboxylase [ACCase; acetyl-CoA:carbon-dioxide ligase (ADP-forming), EC 6.4.1.2] catalyzes the ATP-dependent carboxylation of acetyl CoA to produce malonyl CoA. In plants, malonyl CoA is needed for plastid localized fatty acid biosynthesis and for a variety of pathways in the cytoplasm including flavonoid biosynthesis. We have determined the full

11. Inhibition of Acetyl-CoA Carboxylase Activity by Haloxyfop and Tralkoxydim
Acetyl-coenzyme A (CoA) carboxylase from maize (Zea mays L.) is inhibited by nanomolar concentrations of both haloxyfop, an aryloxyphenoxypropionate, and tralkoxydim, a cyclohexanedione herbicide. These results suggest that acetyl-CoA carboxylase, which catalyzes the first committed step in fatty acid biosynthesis, may be the target of these herbicides, cont
