Bile acyl-CoA synthetase is an enzyme that in humans is encoded by the SLC27A5 gene. [5] [6] [7]
The protein encoded by this gene is an isozyme of very long-chain acyl-CoA synthetase (VLCS). It is capable of activating very long-chain fatty-acids containing 24- and 26-carbons. It is expressed in liver and associated with endoplasmic reticulum but not with peroxisomes. Its primary role is in fatty acid elongation or complex lipid synthesis rather than in degradation. This gene has a mouse ortholog. [7]
Very long-chain specific acyl-CoA dehydrogenase, mitochondrial (VLCAD) is an enzyme that in humans is encoded by the ACADVL gene.
Fatty acid transport proteins are a family of trans-membrane transport proteins, which allow and enhance the uptake of long chain fatty acids into cells. This subfamily is part of the solute carrier protein family. Within humans this family contains six very homologous proteins, which are expressed in all tissues of the body which use fatty acids:
The long chain fatty acyl-CoA ligase is an enzyme of the ligase family that activates the oxidation of complex fatty acids. Long chain fatty acyl-CoA synthetase catalyzes the formation of fatty acyl-CoA by a two-step process proceeding through an adenylated intermediate. The enzyme catalyzes the following reaction,
Acyl-CoA synthetase long-chain family member 6 is an enzyme that in humans is encoded by the ACSL6 gene. Long-chain acyl-CoA synthetases such as ACSL6, catalyze the formation of acyl-CoA from fatty acids, ATP, and CoA.
Long-chain-fatty-acid—CoA ligase 1 is an enzyme that in humans is encoded by the ACSL1 gene.
Long-chain-fatty-acid—CoA ligase 5 is an enzyme that in humans is encoded by the ACSL5 gene.
Long-chain-fatty-acid—CoA ligase 3 is an enzyme that in humans is encoded by the ACSL3 gene.
Acyl-CoA thioesterase 2, also known as ACOT2, is an enzyme which in humans is encoded by the ACOT2 gene.
Very long-chain acyl-CoA synthetase is an enzyme that in humans is encoded by the SLC27A2 gene.
Long-chain fatty acid transport protein 4 is a protein that in humans is encoded by the SLC27A4 gene. This membrane protein is also called FATP4 or ACSVL5. The purified protein shows enzyme activity, esterifying long and very long chain fatty acids with Coenzyme A. It is debated whether it is also a fatty acid transporter at the plasma membrane.
Acyl-CoA Synthetase, Bubblegum Family, member 1 (ACSBG1) is an enzyme that in humans is encoded by the ACSBG1 gene.
Acyl-coenzyme A thioesterase 4 is an enzyme that in humans is encoded by the ACOT4 gene.
Acyl-coenzyme A thioesterase 11 also known as StAR-related lipid transfer protein 14 (STARD14) is an enzyme that in humans is encoded by the ACOT11 gene. This gene encodes a protein with acyl-CoA thioesterase activity towards medium (C12) and long-chain (C18) fatty acyl-CoA substrates which relies on its StAR-related lipid transfer domain. Expression of a similar murine protein in brown adipose tissue is induced by cold exposure and repressed by warmth. Expression of the mouse protein has been associated with obesity, with higher expression found in obesity-resistant mice compared with obesity-prone mice. Alternative splicing results in two transcript variants encoding different isoforms.
Long-chain fatty acid transport protein 6 is a protein that in humans is encoded by the SLC27A6 gene.
Acyl-coenzyme A synthetase ACSM2B, mitochondrial is an enzyme that in humans is encoded by the ACSM2B gene.
Long-chain fatty acid transport protein 1 (FATP1) is a protein that in humans is encoded by the SLC27A1 gene.
Long-chain fatty acid transport protein 3 is a protein that in humans is encoded by the SLC27A3 gene.
Acyl-CoA thioesterase 9 is a protein that is encoded by the human ACOT9 gene. It is a member of the acyl-CoA thioesterase superfamily, which is a group of enzymes that hydrolyze Coenzyme A esters. There is no known function, however it has been shown to act as a long-chain thioesterase at low concentrations, and a short-chain thioesterase at high concentrations.
Acyl-CoA thioesterase 13 is a protein that in humans is encoded by the ACOT13 gene. This gene encodes a member of the thioesterase superfamily. In humans, the protein co-localizes with microtubules and is essential for sustained cell proliferation.
Acyl-CoA thioesterase 1 is a protein that in humans is encoded by the ACOT1 gene.
