Chemical genetics of acetyl-CoA carboxylases.

Molecular cloning and characterization of two genes for the biotin carboxylase and carboxyltransferase subunits of acetyl coenzyme A carboxylase in Myxococcus xanthus.

We have cloned a DNA fragment from a genomic library of Myxococcus xanthus using an oligonucleotide probe representing conserved regions of biotin carboxylase subunits of acetyl coenzyme A (acetyl-CoA) carboxylases. The fragment contained two open reading frames (ORF1 and ORF2), designated the accB and accA genes, capable of encoding a 538-amino-acid protein of 58.1 kDa and a 573-amino-acid pro...

Plant biotin-containing carboxylases.

Biotin-containing proteins are found in all forms of life, and they catalyze carboxylation, decarboxylation, or transcarboxylation reactions that are central to metabolism. In plants, five biotin-containing proteins have been characterized. Of these, four are catalysts, namely the two structurally distinct acetyl-CoA carboxylases (heteromeric and homomeric), 3-methylcrotonyl-CoA carboxylase and...

Substrate specificity of the 3 - Methylcrotonyl - CoA and Geranyl - CoA Carboxylases

Holocarboxylase Synthetase 1 Physically Interacts with Histone H3 in Arabidopsis

Biotin is a water-soluble vitamin required by all organisms, but only synthesized by plants and some bacterial and fungal species. As a cofactor, biotin is responsible for carbon dioxide transfer in all biotin-dependent carboxylases, including acetyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and pyruvate carboxylase. Adding biotin to carboxylases is catalyzed by the enzyme holocarboxylas...

Synthesis, Biological Evaluation and Molecular Docking Studies of Piperidinylpiperidines and Spirochromanones Possessing Quinoline Moieties as Acetyl-CoA Carboxylase Inhibitors.

Acetyl-coenzyme A carboxylases (ACCs) play critical roles in the regulation of fatty acid metabolism and have been targeted for the development of drugs against obesity, diabetes and other metabolic diseases. Two series of compounds possessing quinoline moieties were designed, synthesized and evaluated for their potential to inhibit acetyl-CoA carboxylases. Most compounds showed moderate to goo...
