| Native Pyruvate decarboxylase from Thermophillic bacteria | 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. Applications: C-c bond formation: ligation of two aldehyde molecules enantioselectively to 2-hydroxy ketones; preparation of (r)-phenylacetylcarbinol (pac). Group: Enzymes. Synonyms: Pyruvate decarboxylase; EC 4.1.1.1; α-carboxylase (ambiguous); pyruvic decarboxylase; α-ketoacid carboxylase; 2-oxo-acid carboxy-lyase; 9001-04-1; 2-Oxo-acid carboxy-lyase; PDC. Enzyme Commission Number: EC 4.1.1.1. CAS No. 9001-4-1. PDC. Storage: Store at -20°C. Form: Frozen Liquid. Source: Thermophillic bacteria.
