The acetyl-CoA carboxylase present in both wheat germ and total wheat leaf protein contains ca. 220 kDa subunits. It is the major biotin-dependent carboxylase present in wheat chloroplasts. Active acetyl-CoA carboxylase purified from wheat germ is a homodimer with an apparent molecular mass of ca. 500 kDa.

Abstract A biotin carboxyl carrier protein (BCCP) from Escherichia coli has been purified and crystallized. The purified protein was found to be homogeneous by polyacrylamide gel electrophoresis and sedimentation in a synthetic boundary cell. BCCP has a sedimentation coefficient of 1.04 S, a diffusion coefficient ( D 20,w ) of 10.4 × 10 −7 cm 2 ...

Regulation of acetyl-CoA carboxylase
Biochemical Society Transactions, 2006Acetyl-CoA carboxylase (ACC) catalyses the formation of malonyl-CoA, an essential substrate for fatty acid synthesis in lipogenic tissues and a key regulatory molecule in muscle, brain and other tissues. ACC contributes importantly to the overall control of energy metabolism and has provided an important model to explore mechanisms of enzyme control ...

Multi-subunit acetyl-CoA carboxylases
Progress in Lipid Research, 2002Acetyl-CoA carboxylase (ACC) catalyses the first committed step of fatty acid synthesis, the carboxylation of acetyl-CoA to malonyl-CoA. Two physically distinct types of enzymes are found in nature. Bacterial and most plant chloroplasts contain a multi-subunit ACC (MS-ACC) enzyme that is readily dissociated into its component proteins.

Engineering a Novel Acetyl-CoA Pathway for Efficient Biosynthesis of Acetyl-CoA-Derived Compounds
ACS Synthetic Biology, 2023Acetyl-CoA is an essential central metabolite in living organisms and a key precursor for various value-added products as well. However, the intracellular availability of acetyl-CoA limits the efficient production of these target products due to complex and strict regulation. Here, we proposed a new acetyl-CoA pathway, relying on two enzymes, threonine

Regulation of Acetyl-CoA Carboxylase
1983Publisher Summary This chapter discusses the regulation of acetyl-CoA carboxylase. Acetyl-CoA carboxylase catalyzes the ATP-dependent carboxylation of acetyl-CoA in the formation of malonyl-CoA. Malonyl-CoA is then condensed to acetyl-CoA in the process of long-chain fatty acid synthesis.

Purification of Glyoxysomal Acetyl-CoA Acyltransferase
Hoppe-Seyler´s Zeitschrift für physiologische Chemie, 1980Acetyl-CoA acyltransferase was extracted from cotyledons of germinating cucumber seeds and purified to apparent heomogeneity. The purification based primarily on cation exchange chromatography and separation on an affinity gel. The enzyme is a dimer consisting of two subunits of molecular weight 45 000.

The Evolution of Acetyl-CoA Synthase
Origins of life and evolution of the biosphere, 2001Acetyl-coenzyme A synthases (ACS) are Ni-Fe-S containing enzymes found in archaea and bacteria. They are divisible into 4 classes. Class I ACS's catalyze the synthesis of acetyl-CoA from CO2 + 2e-, CoA, and a methyl group, and contain 5 types of subunits (alpha, beta, gamma, delta, and epsilon).

Molecular biology of acetyl-CoA metabolism
Biochemical Society Transactions, 2000We have characterized the expression of potential acetyl-CoA-generating genes (acetyl-CoA synthetase, pyruvate decarboxylase, acetaldehyde dehydrogenase, plastidic pyruvate dehydrogenase complex and ATP-citrate lyase), and compared these with the expression of acetyl-CoA-metabolizing genes (heteromeric and homomeric acetyl-CoA carboxylase).

The acetyl-CoA transporter family SLC33
Molecular Aspects of Medicine, 2013The acetyl-CoA (Ac-CoA) transporter, ACATN is a multiple (11 or 12) transmembrane protein in the endoplasmic reticulum. Ac-CoA is transported into the lumen of the endoplasmic reticulum/Golgi apparatus, where it serves as the substrate of acetyltransferases that modify a variety of molecules including the sialic acid residues of gangliosides and lysine
