Where is carnitine acyltransferase I located?
Where is carnitine acyltransferase I located?
outer mitochondrial membrane
The mitochondrion is the site of the β-oxidation pathway that generates acetyl CoA from fatty acids. Fatty acids, as the CoA derivatives, are transported into the mitochondrion by carnitine acyltransferase located in the outer mitochondrial membrane.
Where is carnitine acyltransferase 2 located?
the mitochondria
Carnitine palmitoyltransferase II precursor (CPT2) is a mitochondrial membrane protein which is transported to the mitochondrial inner membrane. CPT2 together with carnitine palmitoyltransferase I oxidizes long-chain fatty acids in the mitochondria.
Where is acyl carnitine formed?
Long-chain acyl-CoAs are converted to acylcarnitines by carnitine palmitoyltransferase 1 (CPT1), which exchanges the CoA moiety for carnitine. CPT1 is located at the outer mitochondrial membrane, and three isoforms are known: CPT1a, 1b, and 1c are encoded by separate genes (21).
What is the location of Camlin Palmitoyltransferase 1 enzyme?

Where is fatty acid synthase located?
cytoplasm
In biochemistry, fatty acid synthesis is the creation of fatty acids from acetyl-CoA and NADPH through the action of enzymes called fatty acid synthases. This process takes place in the cytoplasm of the cell.
Which is the correct listing of the two substrates for carnitine acyltransferase I?
Thus, the two substrates of this enzyme are acetyl-CoA and carnitine, whereas its two products are CoA and O-acetylcarnitine.
What is the difference between CPT1 and CPT2?
CPT1, CPT2, and carnitine-acylcarnitine translocase (CACT) play vital roles in the transport system for FA esterification in the mitochondrial membrane. The transmembrane protein CPT1 is located at the outer mitochondrial membrane, while CPT2 is in the inner of the mitochondrial membrane (Fraser et al., 1997).
What is the location of carnitine palmitoyltransferase I enzyme Mcq?
This gene provides instructions for making an enzyme called carnitine palmitoyltransferase 1A, which is found in the liver . Carnitine palmitoyltransferase 1A is essential for fatty acid oxidation, which is the multistep process that breaks down (metabolizes) fats and converts them into energy.
Where is carnitine found?
Carnitine is in many animal products. Red meat has the highest levels. A 4-ounce beef steak has an estimated 56 mg to 162 mg of carnitine. Carnitine is also found in smaller amounts in chicken, milk and dairy products, fish, beans, and avocado.
What is the location of carnitine palmitoyl?
Carnitine palmitoyltransferase A (CPT-A), located on the external surface of the inner membrane, catalyzes the conversion of cytoplasmic long-chain acyl-CoA and carnitine into acylcarnitine.
What is the role of carnitine acyltransferase I?
Carnitine acyltransferases are a large family of enzymes that play a main role in cellular energy metabolism, i.e. fatty acid oxidation. These enzymes catalyze the reversible exchange of acyl groups (which derive from fatty acids) between coenzyme A and carnitine.
Which fatty acid is commonly attached to proteins to allow membrane localization?
The 14-carbon saturated fatty acid, myristic acid (14:0), is often employed as a lipid anchor for proteins [29]. This may seem an odd choice since myristic acid, in sharp contrast to the other commonly employed fatty acid lipid anchor palmitic acid (16:0), is found in membranes only at very low levels.
