Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

One of five 2-oxo acid decarboxylases (PDC1, PDC5, PDC6, ARO10, and THI3) involved in amino acid catabolism. The enzyme catalyzes the decarboxylation of amino acids, which, in a first step, have been transaminated to the corresponding 2-oxo acids (alpha-keto-acids). In a third step, the resulting aldehydes are reduced to alcohols, collectively referred to as fusel oils or alcohols. Its preferred substrates are the transaminated amino acids derived from leucine (4-methyl-2-oxopentanoate, also alpha-keto-isocaproate) and isoleucine ((3S)-3-methyl-2-oxopentanoate, also alpha-keto-beta-methylvalerate), whereas transaminated valine, transaminated aromatic amino acids, and pyruvate are no substrates. In analogy to the pyruvate decarboxylases the enzyme may in a side-reaction catalyze condensation (or carboligation) reactions leading to the formation of 2-hydroxy ketone, collectively called acyloins. The enzyme is also positively regulating the thiamine metabolism by a molecular mechanism that may involve thiamine concentration sensing and signal transmission.6 Publications

Caution

While genetic evidence suggests this enzyme is involved in leucine and isoleucine catabolism (PubMed:9341119, PubMed:10753893), no decarboxylase enzymatic activity could be detected in cell extracts of S.cerevisiae strains expressing the individual gene (PubMed:22904058).3 Publications
