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 ...
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 ...
The New York City Economic Development Corporation's Early Stage Life Sciences Funding Initiative and venture capital partners, including Celgene, General Electric Ventures, and Eli Lilly, committed a minimum of US$100 million to help launch 15 to 20 ventures in life sciences and biotechnology in 2014, [6] and in January 2018, the City of New ...
The BCAT enzyme catalyzes the conversion of BCAAs and α-ketoglutarate into branched chain α-keto acids and glutamate. 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 ...
Whey protein contains high levels of all the essential amino acids and branched-chain amino acids. It also has the highest content of the amino acid cysteine, which aids in the biosynthesis of glutathione. For bodybuilders, whey protein provides amino acids used to aid in muscle recovery. [15]

Tissue transaminase activities can be investigated by incubating a homogenate with various amino/keto acid pairs. Transamination is demonstrated if the corresponding new amino acid and keto acid are formed, as revealed by paper chromatography. Reversibility is demonstrated by using the complementary keto/amino acid pair as starting reactants.
