Acyl CoA binding protein and cholesterol differentially alter fatty acyl CoA utilization by microsomal acyl-CoA:cholesterol transferase by

Acyl-CoA dehydrogenases and acyl-CoA oxidases

Acyl-CoA dehydrogenases and acyl-CoA oxidases are two closely related FAD-containing enzyme families that are present inmitochondria andperoxisomes, respectively. They catalyze the dehydrogenation of acyl-CoA thioesters to the corresponding trans-2-enoyl-CoA. This review examines the structure of medium chain acyl-CoA dehydrogenase, as a representative of the dehydrogenase family, with respect ...

Membrane charge and curvature determine interaction with acyl-CoA binding protein (ACBP) and fatty acyl-CoA targeting.

Although acyl-CoA binding protein (ACBP) stimulates utilization of long-chain fatty acyl-CoA by a variety of membrane-bound enzymes, it is not known whether ACBP directly interacts with membranes. To test this hypothesis, mouse recombinant (mr) ACBP was engineered to contain the native mouse ACBP amino acid sequence expressed as a fusion protein at high levels (>150 mg/L) in Escherichia coli. P...

Substrate specificities of rat liver peroxisomal acyl-CoA oxidases: palmitoyl-CoA oxidase (inducible acyl-CoA oxidase), pristanoyl-CoA oxidase (non-inducible acyl-CoA oxidase), and trihydroxycoprostanoyl-CoA oxidase.

Rat liver peroxisomes contain three acyl-CoA oxidases:palmitoyl-CoA oxidase, pristanoyl-CoA oxidase, and trihydroxycoprostanoyl-CoA oxidase. The three oxidases were separated by anion-exchange chromatography of a partially purified oxidase preparation, and the column eluate was analyzed for oxidase activity with different acyl-CoAs. Short chain mono (hexanoyl-) and dicarboxylyl (glutaryl-)-CoAs...

Microsomal long chain fatty acyl-CoA transacylation: differential effect of sterol carrier protein-2.

The recent discovery that sterol carrier protein-2 (SCP-2) binds long chain++ (LCFA-CoA) with high affinity (A. Frolov et al., J. Biol. Chem. 271 (1997) 31878-31884) suggests new possible functions of this protein in LCFA-CoA metabolism. The purpose of the present investigation was to determine whether SCP-2 differentially modulated microsomal LCFA-CoA transacylation to cholesteryl esters, tria...
