Pyruvate Decarboxylation to Acetyl-CoA

Citrobacter youngae ATCC 29220
The multi-enzyme complex catalyze three reactions that constitute a cycle, which is an essential source of acetyl-CoA. Pyruvate dehydrogenase E1 and dihydrolipoyllysine-residue acetyltransferase catalyzes pyruvic acid to acetyl-CoA and CO2. Acetyl-CoA is required for the TCA cycle. Lipoamide dehydrogenase reduces NAD+ to NADH.

Pyruvate Dehydrogenase Complex Deficiency

Homo sapiens
Pyruvate dehydrogenase complex deficiency results from a mutation in the E1-alpha polypeptide gene (PDHA1). PDHA1 encodes the pyruvate dehydrogenase complex (PDC) a critical complex that converts pyruvate from glycolysis to acetyl CoA for the citric acid cycle. This conversion step links glycolysis and the citric acid cycle. A defect in this complex causes accumulation of lactate and pyruvate in the blood; lactate and pyruvic acid in the spinal fluid; and lactate in the urine. Symptoms include lactic and metabolic acidosis, motor retardation, dystonia, growth and mental retardation, and respiratory distress.

Pyruvate Dehydrogenase Deficiency (E2)

Homo sapiens
Pyruvate Dehydrogenase (PDH) Deficiency is an X linked disease where individuals have a reduced number of functioning PDH complexes ultimately affecting the mitochondria’s energy metabolism. In a healthy individual, PDH complex catalyzes the conversion of pyruvate to acetyl coenzyme A, therefore PDH deficiency can cause the accumulation of excess pyruvate and lactic acid. PDH deficiency presents itself in a variety of ways, however since the brain obtains most of it’s energy from aerobic oxidation of glucose, all PDH deficient individuals have some degree of neurological impairment. Other symptoms range from fatal lactic acidosis in the newborns, chronic neurodegenerative conditions, brain lesions, cerebral atrophy and much more. Due to the fatal nature of the disease many with this condition do not live past childhood, however there are some that survive to adolescents and adulthood. Treatments have tried to minimize systemic lactic acid accumulation by feeding patients high fat/low carbohydrate diets. However, this does not reverse neurological structural damage already present and therefore does little to influence the end results.
