一般說明
丙酮酸脱羧酶(PDC)通常出现在萌发阶段的植物种子中，特别是当整个植物胚都包裹氧透过性种皮时。
應用
丙酮酸脱羧酶(PDC)可用于研究参与硫胺素焦磷酸(TPP)结合的残基。 也可用于研究植物发酵途径调控。
丙酮酸脱羧酶（来自面包酵母/酿酒酵母）已用于评估有益代谢酶调控系统鉴定(SIMMER,systematic identification of meaningful metabolic enzyme regulation)方法发现未知酵母调控作用的能力。
生化／生理作用
丙酮酸脱羧酶(PDC)是可在细胞质中催化丙酮酸脱羧成为乙醛和二氧化碳的同四聚体酶。 丙酮酸脱羧酶(PDC)依赖辅因子硫胺素焦磷酸(TPP)和镁。 PDC具有1个β-α-β结构，形成平行β-折叠片。
丙酮酸脱羧酶(PDC)活跃参与多种细菌、酵母和植物种子的厌氧代谢。
單位定義
在pH 6.0、25℃条件下，一个单位每分钟可将1.0 μmole丙酮酸转化为乙醛。
外觀
溶于3.2 M (NH4)2SO4(pH 6.5)的悬液，添加5%甘油、5 mM磷酸钾、1 mM乙酸镁、0.5 mM EDTA和25 μM辅羧酶帮助稳定。
準備報告
分离纯化处理时不曾使用重金属。

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.
