What is the normal function of branched chain amino acids BCAA in the body?

BCAAs are amino acids that suppress protein breakdown and are used as an efficient energy source during exercise.

What is BCAA oxidation?

It is known that BCAA oxidation is promoted by exercise. The mechanism responsible for this phenomenon is attributed to activation of the branched-chain alpha-keto acid dehydrogenase (BCKDH) complex, which catalyzes the second-step reaction of the BCAA catabolic pathway and is the rate-limiting enzyme in the pathway.

How are branched chain amino acids metabolized?

In contrast to the other 17 amino acids, which are predominantly metabolized in the liver, BCAAs are poorly metabolized during first pass through the liver as the liver expresses only low levels of the mitochondrial branched chain aminotransferase (BCAT2 or BCATm), the first enzyme in the catabolism of BCAAs in most …

What is the function of branched chain aminotransferase 3?

“Arabidopsis branched-chain aminotransferase 3 functions in both amino acid and glucosinolate biosynthesis.” Cited for: FUNCTION, CATALYTIC ACTIVITY, BIOPHYSICOCHEMICAL PROPERTIES, TISSUE SPECIFICITY, INDUCTION, DISRUPTION PHENOTYPE.

Which is the gene for branched chain amino acid transaminase?

Branched-chain amino acid aminotransferase (BCAT), also known as branched-chain amino acid transaminase, is an aminotransferase enzyme (EC 2.6.1.42) which acts upon branched-chain amino acids (BCAAs). It is encoded by the BCAT2 gene in humans.

Where are branched chain amino acids found in the body?

The structure to the right of branched chain amino acid aminotransferase was found using X-ray diffraction with a resolution of 2.20 Å. The branched-chain amino acid aminotransferase found in this image was isolated from mycobacteria. This protein is made up of two identical polypeptide chains.

Why are aminotransferases used in synthetic organic chemistry?

Aminotransferases are used because they can accomplish a typically multi-step reaction in one step, can perform reactions on a wide range of substrates, and have high regioselectivity and enantioselectivity. In synthetic organic chemistry, BCATs are typically used for the conversion of L-Leucine to 2-ketoglutarate.
