Description

Leucine (abbreviated as Leu or L) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a nonpolar branched chain amino acid, because of the hydrophobic nature of its branched alkyl side chain. Leucine is synthesized in yeast via several steps starting from pyruvic acid. The initial part of the pathway also leads to valine. The intermediate alpha-ketoisovalerate is converted to alpha-isopropylmalate and then β-isopropylmalate, which is dehydrogenated to alpha-ketoisocaproate, which in the final step undergoes reductive amination. Enzymes involved in leucine biosynthesis include: 1) Acetolactate synthase; 2) Acetohydroxy acid isomeroreductase; 3) Dihydroxyacid dehydratase; 4) alpha-Isopropylmalate synthase; 5) alpha-Isopropylmalate isomerase, and 6) Leucine aminotransferase. S. cerevisiae degrade the branched-chain amino acids (valine, leucine, and iso-leucine) via the Ehrlich pathway. This pathway consists of 3 steps: 1) deamination of the amino acid to the corresponding alpha-keto acid; 2) decarboxylation of the resulting alpha-keto acid to the respective aldehyde; and, 3) reduction of the aldehyde to form the corresponding long chain or complex alcohol, known as a fusel alcohol or fusel oil. Fusel alcohols are important flavor and aroma compounds in yeast-fermented food products and beverages. Each of the three steps in branched-chain amino acid degradation can be catalyzed by more than one isozyme; which enzyme is used appears to depend on the amino acid, the carbon source and the stage of growth of the culture. In leucine degradation, Thi3p is believed to be the major decarboxylase.
