2. Branched-chain amino acid - Wikipedia

   en.wikipedia.org/wiki/Branched-chain_amino_acid

   A branched-chain amino acid (BCAA) is an amino acid having an aliphatic side-chain with a branch (a central carbon atom bound to three or more carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine, and valine. [1] Non-proteinogenic BCAAs include 2-aminoisobutyric acid and alloisoleucine. Leucine ...

3. Branched-chain amino acid aminotransferase - Wikipedia

   en.wikipedia.org/wiki/Branched-chain_amino_acid...

   The biological function of branched-chain amino acid aminotransferases is to catalyse the synthesis or degradation of the branched chain amino acids leucine, isoleucine, and valine. [3] In humans, branched chain amino acids are essential and are degraded by BCATs.

4. Branched chain amino acid exporter family - Wikipedia

   en.wikipedia.org/wiki/Branched_chain_amino_acid...

   In Corynebacterium glutamicum, BrnFE exports branched chain amino acids isoleucine, leucine, and valine, as well as methionine and homoserine. [3] [5] [8] The greatest induction of BrnFE expression occurs under high methionine concentrations, suggesting that methionine may actually be the native substrate rather than a branched-chain amino acid ...

5. Branched chain amino acid transaminase 1 - Wikipedia

   en.wikipedia.org/wiki/Branched_chain_amino_acid...

   This gene encodes the cytosolic form of the enzyme branched-chain amino acid transaminase. This enzyme catalyzes the reversible transamination of branched-chain alpha-keto acids (BCKAs) to the branched-chain amino acids (BCAAs) valine, leucine and isoleucine, which are essential for cell growth.

6. Branched-chain alpha-keto acid dehydrogenase complex

   en.wikipedia.org/wiki/Branched-chain_alpha-keto...

   As previously mentioned, BCKDC's primary function in mammals is to catalyze an irreversible step in the catabolism of branched-chain amino acids. However BCKDC has a relatively broad specificity, also oxidizing 4-methylthio-2-oxobutyrate and 2-oxobutyrate at comparable rates and with similar Km values as for its branched-chain amino acid ...

7. BCKDHA - Wikipedia

   en.wikipedia.org/wiki/BCKDHA

   The second major step in the catabolism of the branched-chain amino acids (isoleucine, leucine, and valine) is catalyzed by the branched-chain alpha-keto acid dehydrogenase complex (BCKD; EC 1.2.4.4), an inner-mitochondrial enzyme complex that consists of 3 catalytic components: a heterotetrameric (alpha2, beta2) branched-chain alpha-keto acid decarboxylase (E1), a homo-24-meric dihydrolipoyl ...
