Pyruvate dehydrogenase deficiency is characterized by the buildup of a chemical called lactic acid in the body and a variety of neurological problems. Signs and symptoms of this condition usually first appear shortly after birth, and they can vary widely among affected individuals.
Pyruvate dehydrogenase deficiency | About the Disease | GARD
Pyruvate dehydrogenase complex (PDC) deficiency is a type of metabolic disease. This means that the body is not able to efficiently break down nutrients in food to be used for energy. Symptoms of PDC deficiency include signs of metabolic dysfunction such as extreme tiredness (lethargy), poor feeding, and rapid breathing (tachypnea).

丙酮酸脱氢酶的结构、功能与相关疾病 - 知乎 - 知乎专栏
PDH是典型的多酶体系,将催化连续反应的几种酶结合成复杂有序的结构,以提高效率。 原核生物的复合体较为简单,大肠杆菌的PDH含有12个E1二聚体,24个E2和6个E3二聚体。 真核生物的复合体结构更加复杂,比如人的复合体除含有30个E1四聚体(α2 β 2),60个E2和12个E3二聚体外,还含有三种调控蛋白,包括E3结合蛋白(E3BP),丙酮酸脱氢酶激酶(PDK)和丙酮酸脱氢酶磷酸酶(PDP)。 原核生物的PDH直径30纳米,真核的直径50纳米,而核糖体的直径才20纳 …

丙酮酸脱氢酶(PDH) - Abcam中文官网
丙酮酸脱氢酶复合物 (PDH)将柠檬酸循环和随后的氧化磷酸化与糖酵解、糖异生以及脂质和氨基酸代谢途径联系起来。 PDH催化丙酮酸的氧化脱羧生成乙酰辅酶A (乙酰辅酶A)、NADH和CO2。 PDH促进碳水化合物的使用以满足能量需求:当哺乳动物的碳水化合物储存耗尽时,PDH活性下调,以限制氧化磷酸化对葡萄糖的使用。 脂肪酸或酮体被用作心脏和骨骼肌等组织的能量来源。 PDH是一种9.5 MDa复合物,由三种酶的多个副本组成:丙酮酸脱氢酶 (E1)、二氢脂酰胺转乙 …
