Descrição geral
Pyruvate decarboxylase (PDC) usually appear in plant seeds at the time of germination, especially when the plant embryo is totally covered by an oxygen-impermeable testa.
Aplicação
Pyruvate Decarboxylase from baker′s yeast (S. cerevisiae) has been used to evaluate the power of systematic identification of meaningful metabolic enzyme regulation (SIMMER) for finding unknown yeast regulatory interactions.
Pyruvate decarboxylase (PDC) is used to study residues involved in thiamine pyrophosphate (TPP) binding. It is used to study the regulation of fermentation pathways in plant species.
Ações bioquímicas/fisiológicas
Pyruvate decarboxylase (PDC) is a homotetrameric enzyme that catalyses the decarboxylation of pyruvic acid to acetaldehyde and carbon dioxide in the cytoplasm. Pyruvate decarboxylase depends on cofactors thiamine pyrophosphate (TPP) and magnesium. PDC contains a β-α-β structure, yielding parallel β-sheets.
Pyruvate decarboxylase (PDC) actively participates in the anaerobic metabolism of several bacteria, yeast and plant seeds.
Definição da unidade
One unit will convert 1.0 μmole of pyruvate to acetaldehyde per min at pH 6.0 at 25 °C.
forma física

The crystal structure of brewers' yeast pyruvate decarboxylase, a thiamin diphosphate dependent alpha-keto acid decarboxylase, has been determined to 2.4-A resolution. The homotetrameric assembly contains two dimers, exhibiting strong intermonomer interactions within each dimer but more limited ones between dimers.
