Respiration, oxidative phosphorylation and yields in aerobic bacteria.
in effluent-treatment processes, the major concern is with biomass production, whereas in many microbial processes it is important to produce an extracellular product, e.g. amino acid, organic acid or polysaccharide. For microbial-product formation there must often be a diversion of energy, reductant and carbon away from biomass production into product formation, and a possible energy-dependent...
متن کاملRespiratory Enzymes in Oxidative Phosphorylation
In a complex enzymatic sequence the site of action of substrates and inhibitors is clearly marked by the way they affect the steady state concentrations of the components of the system (1). Antimycin A, for example, inhibits respiration in the succinic oxidase system (2) and at the same time increases the steady state reduction of cytochrome b and decreases that of cytochromes c, a, and aa (3)....
متن کاملOxidative protein folding in bacteria.
Ten years ago it was thought that disulphide bond formation in prokaryotes occurred spontaneously. Now two pathways involved in disulphide bond formation have been well characterized, the oxidative pathway, which is responsible for the formation of disulphides, and the isomerization pathway, which shuffles incorrectly formed disulphides. Disulphide bonds are donated directly to unfolded polypep...
متن کاملRegulation of Oxidative Phosphorylation
Introduction Thyroid hormones (TI Is) affect cellular metabolism via two different pathways. The first one is the socalled nuclear, long-term effect: there the TI I binds to a nuclear receptor and regulates the transcription o f multiple cellular proteins f 11. The other pathway, the short-term extranuclear pathway, is less w d l defined and could in principle be similar to other short-term sig...
متن کاملBarbiturates and oxidative phosphorylation.
It has been claimed that barbiturates uncouple oxidative phosphorylations (Brody & Bain, 1954; Brody, 1955). These authors have demonstrated that during the oxidation of pyruvate by liver and brain mitochondria, phosphate uptake was lowered proportionately more than oxygen uptake. Support for the uncoupling theory was derived from certain similarities between the barbiturates and 2:4dinitrophen...
