    4.1.1.72 | physiological function |
metabolic routes between isoleucine and active amyl alcohol all involve the initial decarboxylation of isoleucine to 2-oxo-3-methylvalerate and subsequent decarboxylation to 2-methylbutanoate. One of the decarboxylases encoded by PDC1, PDC5, PDC6, YDL080c, or YDR380w must be present to allow yeast to utilize 2-oxo-3-methylvalerate. Any one of this family of decarboxylases is sufficient to allow the catabolism of isoleucine to active amyl alcohol |

One of the decarboxylases encoded by PDC1, PDC5, PDC6, YDL080c, or YDR380w must be present to allow yeast to utilize 2-oxo-3-methylvalerate. Any one of this family of decarboxylases is sufficient to allow the catabolism of isoleucine to active amyl alcohol. In leucine catabolism, the enzyme encoded by YDL080c is solely responsible for the decarboxylation of alpha-ketoisocaproate, whereas in valine catabolism any one of the isozymes of pyruvate decarboxylase will decarboxylate 2-oxoisovalerate |

| 4.1.1.72 | physiological function |
pyruvate decarboxylase-like enzyme YDL080c appears to be the major route of decarboxylation of alpha-ketoisocaproate to isoamyl alcohol although at least one other unidentified decarboxylase can substitute to a minor extent |
