The three-dimensional (3D) structure of the protein encoded by C1QBP- P.Leu275Phe was analyzed using the wild type of C1QBP (PDB accession codes 1P32, https://www.rcsb.org/structure/1P32) and the SWISS-MODEL (http://swissmodel.expasy.org/). A regular heartbeat at 86 bpm, and heart sound was strong. We demonstrated that a homozygous C1QBP- P.Leu275Phe mutation in an autosomal recessive inherited mode of inheritance caused early onset combined oxidative phosphorylation deficiency 33 (COXPD 33) (OMIM:617713) in two brothers from a Chinese family. Copyright © 2020 Wang, Li, Sun, Yang, Yang, Liu, Liu, Hu and Zhang. Cellular respiration (oxidative phosphorylation) occurs in the mitochondria, where a series of enzymes catalyze the transfer of electrons to molecular oxygen and the generation of energy-storing adenosine triphosphate (ATP). Furthermore, the suppressive effect of α-KG on ATP synthase plays an important role in the low levels of oxidative phosphorylation in SMMC-7721 cells; this effect could be strengthened by the metabolic poison methotrexate and reversed by L-(-)-malic acid, an accelerator of the malate-aspartate cycle. Their parents were heterozygous mutation carriers without clinical manifestations. COXPD8 is an autosomal recessive disorder due to dysfunction of the mitochondrial respiratory chain. Birth weight, length, and head circumference were within normal limits. Table 1 summarizes the clinical characteristics and the laboratory test results of the two brothers. The GC-MS analyses of organic acids in the urine showed that the values for lactic-2, 2-OH-isovaleric-2, 4-OH-phenyllactic (PHPLA)-3, 2-Keto-isovaleric-OX-2, 2-K o-isocaproic-OX-2, and 2-Keto-3-Methylvaleric-OX-2 were increased (Table 1). He had a blood pressure of 100/58 mmHg with a regular pulse rate at 86 beats per min (bmp). NIH Both phosphorylation and dephosphorylation are carried out by enzymes (e.g., kinases, phosphotransferases). The only alive patient carried homozygous mutation of C1QBP- p.Leu275Phe. |, https://www.frontiersin.org/articles/10.3389/fped.2020.583047/full#supplementary-material, Creative Commons Attribution License (CC BY).

Mitochondrial oxidative phosphorylation is the primary source of cellular ATP with suboptimal mitochondrial function implicated in disorders in which fatigue is a feature (1– 3). Background: Mutations can directly affect oxidative phosphorylation (OXPHOS) subunits or indirectly impair OXPHOS activity by disrupting mitochondrial homeostasis (4). First, the inner mitochondrial membrane (IMM) must be physically intact so that protons can only re-enter the matrix of the mitochondrion by a process coupled to ATP synthesis. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Oxidative phosphorylation is the fourth and final step in cellular respiration. They presenting with progressive external ophthalmoplegia (PEO), mitochondrial myopathy and without any heart involvement. In the cases of children with ages < 16 years, written informed consent was obtained from the parents. The amino acid residues of L and F are all nonpolar amino acids and have similar isoelectric points. Prior research has indicated that a p32 mutation was the suspected cause of mitochondrial respiratory chain disorders (20). To analyze differences between cell types, cell viability, ATP and α-ketoglutaric acid levels, the oxygen consumption rate and extracellular acidification rate, and the expression of key enzymes involved in α-KG metabolism and transfer were examined.

Figure 1 shows the pedigree of the family. They were born after uneventful pregnancies of five generation blood relative Chinese parents. (C,c) Mutation type, F275 is shown in red color. Cardiovasc Res. HCM is one of the most common and important of cardiac phenotype associated with mitochondrial respiratory disorders (16, 17). During the oxidative phosphorylation, the reduction of oxygen by one electron at a time (O 2 → O 2-⋅ → H 2 O 2 → ⋅OH → H 2 O) produces ROS, relatively stable intermediates with one unpaired electron . YY, BL, FL, and WH: validation. Marchet et al. Production of ATP within the living system occurs in many ways. B, The oxidative phosphorylation signalling pathway (P‐value = 6.2e−49) played a crucial role in pathogenesis of GC. Feichtinger et al. The clinical symptoms include left ventricular hypertrophy, fatiguability and ptosis. Clinical investigations such as imaging, cardiac studies, and endocrine investigations are often supportive of a diagnosis and form an important part of the clinical investigation. Eur Heart J. The UCG examination showed that the thickness of END significantly increased to ~5.1 mm. [Research progress on energy metabolism of Plasmodium at erythrocytic stage]. Uncouplers are hydrophobic molecules with a dissociable proton • The ETC remains intact and electrons are transferred to O2 to generate H2O. The identified mutation was verified among the remaining family members by Sanger sequencing. doi: 10.1093/cvr/cvx095, 7.
