F0 complex of the Escherichia coli ATP synthase. Not all monomers of the subunit c oligomer are involved in F1 interaction. (1/160)

The antigenic determinants of mAbs against subunit c of the Escherichia coli ATP synthase were mapped by ELISA using overlapping synthetic heptapeptides. All epitopes recognized are located in the hydrophilic loop region and are as follows: 31-LGGKFLE-37, 35-FLEGAAR-41, 36-LEGAAR-41 and 36-LEGAARQ-42. Binding studies with membrane vesicles of different orientation revealed that all mAbs bind to everted membrane vesicles independent of the presence or absence of the F1 part. Although the hydrophilic region of subunit c and particularly the highly conserved residues A40, R41, Q42 and P43 are known to interact with subunits gamma and epsilon of the F1 part, the mAb molecules have no effect on the function of F0. Furthermore, it could be demonstrated that the F1 part and the mAb molecule(s) are bound simultaneously to the F0 complex suggesting that not all c subunits are involved in F1 interaction. From the results obtained, it can be concluded that this interaction is fixed, which means that subunits gamma and epsilon do not switch between the c subunits during catalysis and furthermore, a complete rotation of the subunit c oligomer modified with mAb(s) along the stator of the F1F0 complex, proposed to be composed of at least subunits b and delta, seems to be unlikely.  (+info)

Chemical mechanism of ATP synthase. Magnesium plays a pivotal role in formation of the transition state where ATP is synthesized from ADP and inorganic phosphate. (2/160)

The chemical mechanism by which ATP synthases catalyze the synthesis of ATP remains unknown despite the recent elucidation of the three-dimensional structures of two forms of the F(1) catalytic sector (subunit stoichiometry, alpha(3)beta(3)gammadeltaepsilon). Lacking is critical information about the chemical events taking place at the catalytic site of each beta-subunit in the transition state. In an earlier report (Ko, Y. H., Bianchet, M. A., Amzel, L.M., and Pedersen, P. L. (1997) J. Biol. Chem. 272, 18875-18881), we provided evidence for transition state formation in the presence of Mg(2+), ADP, and orthovanadate (V(i)), a photoreactive phosphate analog with a trigonal bipyramidal geometry resembling that of the gamma-P of ATP in the transition state of enzymes like myosin. In the presence of ultraviolet light and O(2,) the MgADP.V(i)-F(1) complex was cleaved within the P-loop (GGAGVGKT) of a single beta-subunit at alanine 158, implicating this residue as within contact distance of the gamma-P of ATP in the transition state. Here, we report that ADP, although facilitating transition state formation, is not essential. In the presence of Mg(2+) and V(i) alone the catalytic activity of the resultant MgV(i)-F(1) complex is inhibited to nearly the same extent as that observed for the MgADP. V(i)-F(1) complex. Inhibition is not observed with ADP, Mg(2+), or V(i) alone. Significantly, in the presence of ultraviolet light and O(2,) the MgV(i)-F(1) complex is cleaved also within the P-loop of a single beta-subunit at alanine 158 as confirmed by Western blot analyses with two different antibodies, by N-terminal sequence analyses, and by quantification of the amount of unreacted beta-subunits. These novel findings indicate that Mg(2+) plays a pivotal role in transition state formation during ATP synthesis catalyzed by ATP synthases, a role that involves both its preferential coordination with P(i) and the repositioning of the P-loop to bring the nonpolar alanine 158 into the catalytic pocket. A reaction scheme for ATP synthases depicting a role for Mg(2+) in transition state formation is proposed here for the first time.  (+info)

Catalytic activities of mitochondrial ATP synthase in patients with mitochondrial DNA T8993G mutation in the ATPase 6 gene encoding subunit a. (3/160)

We investigated the biochemical phenotype of the mtDNA T8993G point mutation in the ATPase 6 gene, associated with neurogenic muscle weakness, ataxia, and retinitis pigmentosa (NARP), in three patients from two unrelated families. All three carried >80% mutant genome in platelets and were manifesting clinically various degrees of the NARP phenotype. Coupled submitochondrial particles prepared from platelets capable of succinate-sustained ATP synthesis were studied using very sensitive and rapid luminometric and fluorescence methods. A sharp decrease (>95%) in the succinate-sustained ATP synthesis rate of the particles was found, but both the ATP hydrolysis rate and ATP-driven proton translocation (when the protons flow from the matrix to the cytosol) were minimally affected. The T8993G mutation changes the highly conserved residue Leu(156) to Arg in the ATPase 6 subunit (subunit a). This subunit, together with subunit c, is thought to cooperatively catalyze proton translocation and rotate, one with respect to the other, during the catalytic cycle of the F(1)F(0) complex. Our results suggest that the T8993G mutation induces a structural defect in human F(1)F(0)-ATPase that causes a severe impairment of ATP synthesis. This is possibly due to a defect in either the vectorial proton transport from the cytosol to the mitochondrial matrix or the coupling of proton flow through F(0) to ATP synthesis in F(1). Whatever mechanism is involved, this leads to impaired ATP synthesis. On the other hand, ATP hydrolysis that involves proton flow from the matrix to the cytosol is essentially unaffected.  (+info)

Supercomplexes in the respiratory chains of yeast and mammalian mitochondria. (4/160)

Around 30-40 years after the first isolation of the five complexes of oxidative phosphorylation from mammalian mitochondria, we present data that fundamentally change the paradigm of how the yeast and mammalian system of oxidative phosphorylation is organized. The complexes are not randomly distributed within the inner mitochondrial membrane, but assemble into supramolecular structures. We show that all cytochrome c oxidase (complex IV) of Saccharomyces cerevisiae is bound to cytochrome c reductase (complex III), which exists in three forms: the free dimer, and two supercomplexes comprising an additional one or two complex IV monomers. The distribution between these forms varies with growth conditions. In mammalian mitochondria, almost all complex I is assembled into supercomplexes comprising complexes I and III and up to four copies of complex IV, which guided us to present a model for a network of respiratory chain complexes: a 'respirasome'. A fraction of total bovine ATP synthase (complex V) was isolated in dimeric form, suggesting that a dimeric state is not limited to S.cerevisiae, but also exists in mammalian mitochondria.  (+info)

Differential regulation of exonic regulatory elements for muscle-specific alternative splicing during myogenesis and cardiogenesis. (5/160)

Muscle-specific isoform of the mitochondrial ATP synthase gamma subunit (F(1)gamma) was generated by alternative splicing, and exon 9 of the gene was found to be lacking particularly in skeletal muscle and heart tissue. Recently, we reported that alternative splicing of exon 9 was induced by low serum or acidic media in mouse myoblasts, and that this splicing required de novo protein synthesis of a negative regulatory factor (Ichida, M., Endo, H., Ikeda, U., Matsuda, C., Ueno, E., Shimada, K., and Kagawa, Y. (1998) J. Biol. Chem. 273, 8492-8501; Hayakawa, M., Endo, H., Hamamoto, T., and Kagawa, Y. (1998) Biochem. Biophys. Res. Commun. 251, 603-608). In the present report, we identified a cis-acting element on the muscle-specific alternatively spliced exon of F(1)gamma gene by an in vivo splicing system using cultured cells and transgenic mice. We constructed a F(1)gamma wild-type minigene, containing the full-length gene from exon 8 to exon 10, and two mutants; one mutant involved a pyrimidine-rich substitution on exon 9, whereas the other was a purine-rich substitution, abbreviated as F(1)gamma Pu-del and F(1)gamma Pu-rich mutants, respectively. Based on an in vivo splicing assay using low serum- or acid-stimulated splicing induction system in mouse myoblasts, Pu-del mutation inhibited exon inclusion, indicating that a Pu-del mutation would disrupt an exonic splicing enhancer. On the other hand, the Pu-rich mutation blocked muscle-specific exon exclusion following both inductions. Next, we produced transgenic mice bearing both mutant minigenes and analyzed their splicing patterns in tissues. Based on an analysis of F(1)gamma Pu-del minigene transgenic mice, the purine nucleotide of this element was shown to be necessary for exon inclusion in non-muscle tissue. In contrast, analysis of F(1)gamma Pu-rich minigene mice revealed that the F(1)gamma Pu-rich mutant exon had been excluded from heart and skeletal muscle of these transgenic mice, despite the fact mutation of the exon inhibited muscle-specific exon exclusion in myotubes of early embryonic stage. These results suggested that the splicing regulatory mechanism underlying F(1)gamma pre-mRNA differed between myotubes and myofibers during myogenesis and cardiogenesis.  (+info)

Catalytic site forms and controls in ATP synthase catalysis. (6/160)

A suggested minimal scheme for substrate binding by and interconversion of three forms of the catalytic sites of the ATP synthase is presented. Each binding change, that drives simultaneous interchange of the three catalytic site forms, requires a 120 degrees rotation of the gamma with respect to the beta subunits. The binding of substrate(s) at two catalytic sites is regarded as sufficing for near maximal catalytic rates to be attained. Although three sites do not need to be filled for rapid catalysis, during rapid bisite catalysis some enzyme may be transiently present with three sites filled. Forms with preferential binding for ADP and P(i) or for ATP are considered to arise from the transition state and participate in other steps of the catalysis. Intermediate forms and steps that may be involved are evaluated. Experimental evidence for energy-dependent steps and for control of coupling to proton translocation and transition state forms are reviewed. Impact of relevant past data on present understanding of catalytic events is considered. In synthesis a key step is suggested in which proton translocation begins to deform an open site so as to increase the affinity for ADP and P(i), that then bind and pass through the transition state, and yield tightly bound ATP in one binding change. ADP binding appears to be a key parameter controlling rotation during synthesis. In hydrolysis ATP binding to a loose site likely precedes any proton translocation, with proton movement occurring as the tight site form develops. Aspects needing further study are noted. Characteristics of the related MgADP inhibition of the F(1) ATPases that have undermined many observations are summarized, and relations of three-site filling to catalysis are assessed.  (+info)

The epsilon subunit of bacterial and chloroplast F(1)F(0) ATPases. Structure, arrangement, and role of the epsilon subunit in energy coupling within the complex. (7/160)

Recent studies show that the epsilon subunit of bacterial and chloroplast F(1)F(0) ATPases is a component of the central stalk that links the F(1) and F(0) parts. This subunit interacts with alpha, beta and gamma subunits of F(1) and the c subunit ring of F(0). Along with the gamma subunit, epsilon is a part of the rotor that couples events at the three catalytic sites sequentially with proton translocation through the F(0) part. Structural data on the epsilon subunit when separated from the complex and in situ are reviewed, and the functioning of this polypeptide in coupling within the ATP synthase is considered.  (+info)

The rotary binding change mechanism of ATP synthases. (8/160)

The F(0)F(1) ATP synthase functions as a rotary motor where subunit rotation driven by a current of protons flowing through F(0) drives the binding changes in F(1) that are required for net ATP synthesis. Recent work that has led to the identification of components of the rotor and stator is reviewed. In addition, a model is proposed to describe the transmission of energy from four proton transport steps to the synthesis of one ATP. Finally, some of the requirements for efficient energy coupling by a rotary binding change mechanism are considered.  (+info)

These disorders are caused by changes in specific genes that fail to function properly, leading to a cascade of effects that can damage cells and tissues throughout the body. Some inherited diseases are the result of single gene mutations, while others are caused by multiple genetic changes.

Inherited diseases can be diagnosed through various methods, including:

1. Genetic testing: This involves analyzing a person's DNA to identify specific genetic changes that may be causing the disease.
2. Blood tests: These can help identify certain inherited diseases by measuring enzyme levels or identifying specific proteins in the blood.
3. Imaging studies: X-rays, CT scans, and MRI scans can help identify structural changes in the body that may be indicative of an inherited disease.
4. Physical examination: A healthcare provider may perform a physical examination to look for signs of an inherited disease, such as unusual physical features or abnormalities.

Inherited diseases can be treated in various ways, depending on the specific condition and its causes. Some treatments include:

1. Medications: These can help manage symptoms and slow the progression of the disease.
2. Surgery: In some cases, surgery may be necessary to correct physical abnormalities or repair damaged tissues.
3. Gene therapy: This involves using genes to treat or prevent inherited diseases.
4. Rehabilitation: Physical therapy, occupational therapy, and other forms of rehabilitation can help individuals with inherited diseases manage their symptoms and improve their quality of life.

Inherited diseases are a significant public health concern, as they affect millions of people worldwide. However, advances in genetic research and medical technology have led to the development of new treatments and management strategies for these conditions. By working with healthcare providers and advocacy groups, individuals with inherited diseases can access the resources and support they need to manage their conditions and improve their quality of life.

Causes and Inheritance:

Williams syndrome is caused by a deletion of genetic material from chromosome 7, specifically the q11.23 region. This deletion occurs spontaneously, without a known family history or environmental trigger. The disorder is not inherited in a Mendelian pattern, meaning that it does not follow traditional patterns of inheritance.

Diagnosis:

Williams syndrome can be diagnosed through a combination of physical and developmental assessments, as well as genetic testing. Physical features such as broad foreheads and wide mouths are often present at birth, while developmental delays and cognitive impairments may not become apparent until later in childhood. Genetic testing can confirm the diagnosis by identifying the deletion of genetic material on chromosome 7.

Treatment and Management:

There is no cure for Williams syndrome, but early intervention and specialized management can help individuals with the disorder reach their full potential. Treatment may include:

* Physical therapy to improve fine motor skills and coordination
* Speech and language therapy to improve communication skills
* Occupational therapy to develop daily living skills
* Special education programs tailored to individual needs
* Medications to manage cardiovascular problems, hypertension, and sleep disorders

Prognosis:

The prognosis for individuals with Williams syndrome varies depending on the severity of the symptoms. Some individuals may experience significant developmental delays and cognitive impairments, while others may have fewer or no symptoms. With early intervention and specialized management, many individuals with Williams syndrome can lead fulfilling lives and achieve their full potential.

Inheritance Pattern:

Williams syndrome is not inherited in a Mendelian pattern, meaning that it does not follow traditional patterns of inheritance. The disorder is caused by a spontaneous deletion of genetic material on chromosome 7, and there is no known family history or environmental trigger. Each child of an individual with Williams syndrome has a 50% chance of inheriting the deletion and developing the disorder.

Prenatal Testing:

Prenatal testing for Williams syndrome is available but not routine. The test is typically offered to pregnant women who have a family history of the disorder or who have had a previous child with Williams syndrome. Prenatal testing involves analyzing cells from the developing fetus, usually through chorionic villus sampling (CVS) or amniocentesis.

Genetic Counseling:

Genetic counseling is essential for individuals and families affected by Williams syndrome. A genetic counselor can provide information on the inheritance pattern of the disorder, discuss prenatal testing options, and offer guidance on managing the condition. Genetic counseling can also help families understand the risks and benefits of genetic testing and make informed decisions about their reproductive options.

In conclusion, Williams syndrome is a rare genetic disorder that affects approximately 1 in 10,000 individuals worldwide. It is caused by a spontaneous deletion of genetic material on chromosome 7 and is characterized by developmental delays, cognitive impairments, and cardiovascular problems. Early intervention and specialized management can significantly improve the prognosis for individuals with Williams syndrome. Prenatal testing and genetic counseling are available for families who have a risk of inheriting the disorder. With proper care and support, individuals with Williams syndrome can lead fulfilling lives and achieve their full potential.
