The biotin carboxylase-biotin carboxyl carrier protein complex of Escherichia coli acetyl-CoA carboxylase.
Escherichia coli acetyl-CoA carboxylase (ACC) is composed of four different protein molecules. These proteins form a large but very unstable complex. Hints of a sub-complex between the biotin carboxylase (BC) and biotin carboxyl carrier protein (BCCP) subunits have been reported in the literature, but the complex was not isolated and thus the protein stoichiometry could not be determined. We re...
متن کاملNatural history of propionic acidemia.
Propionic acidemia is an organic acidemia that can lead to metabolic acidosis, coma and death, if not treated appropriately in the acute setting. Recent advancements in treatment have allowed patients with propionic acidemia to live beyond the neonatal period and acute presentation. The natural history of the disease is just beginning to be elucidated as individuals reach older ages. Recent stu...
متن کاملOptic neuropathy in methylmalonic acidemia and propionic acidemia.
BACKGROUND Methylmalonic acidemia (MMA) and propionic acidemia (PA) are rare hereditary disorders of protein metabolism, manifesting early in life with ketoacidosis and encephalopathy and often resulting in chronic complications. Optic neuropathy (ON) has been increasingly recognised in both conditions, mostly through isolated case reports or small cases series. We here report the clinical feat...
متن کاملAtypical presentations of propionic acidemia
One of the most common recessively inherited organic acidemias is the Propionic Acidosis (PA) which results from Propionyle-CoA Carboxylase (PCC) enzyme deficiency that is necessary for the catabolism of the branched chain Amino Acids and other metabolites. Classically this disease presented with high anion gap metabolic acidosis with its clinical consequences. We report 4 patients who presente...
متن کاملAcute management of propionic acidemia.
Propionic acidemia or aciduria is an intoxication-type disorder of organic metabolism. Patients deteriorate in times of increased metabolic demand and subsequent catabolism. Metabolic decompensation can manifest with lethargy, vomiting, coma and death if not appropriately treated. On January 28-30, 2011 in Washington, D.C., Children's National Medical Center hosted a group of clinicians, scient...
