The reduction and specialization of the energy metabolism system is a common trait in the evolution of intracellular parasites. One group of fungi-related parasites, the Microsporidia, seems to have developed this trait far more than other eukaryotes. As an extreme adaptation for a parasitic lifestyle, some of them have completely lost the ability to synthesize ATP, relying heavily upon the metabolic processes of host cells to ensure their own development and reproduction. For a long time, only fragmentary data on the functioning and evolution of the energy metabolism system in microsporidia was available. However, the recent discovery of microsporidia-related microorganisms, the Cryptomycota and Aphelida, alongside with the genome sequencing and new data about basal groups in the Microsporidia has shed new light on this problem. Here, we review recent data about functioning of the energy metabolism system in microsporidia and closely related organisms, and discuss possible evolutionary pathways in the group.

The reversible interconversion of molecular hydrogen and protons is one of the most ancient microbial metabolic reactions and catalyzed by hydrogenases. A widespread yet largely enigmatic group compri...
Microsporidia have the leanest genomes among eukaryotes, and their physiological and genomic simplicity has been attributed to their intracellular, obligate parasitic lifestyle. However, not all micro...
Cancer and aging are both frequently associated with malnutrition, a factor of poor prognosis. In adult cancer patients, this may be related in part to impaired energy metabolism, with higher than pre...
The human brain consumes more energy than any other organ in the body and it relies on an uninterrupted supply of energy in the form of adenosine triphosphate (ATP) to maintain normal cognitive functi...
Diagnosis of patients with microsporiosis relies on pathological findings as well as laboratory detection of the causative organism. The conventional laboratory diagnosis of microsporiosis...
We aim to examine energy metabolism in patients with pulmonary MAC and clarify the causes of emaciation. We will also investigate the following: the relation between energy metabolism and ...
The E-MECHANIC Ancillary Study will measure changes in 24-hour energy expenditure and spontaneous physical activity in a subset of 60 obese individuals enrolled in the main study. We aim t...

Electric power supply devices which convert biological energy, such as chemical energy of metabolism or mechanical energy of periodic movements, into electrical energy.
The chemical reactions involved in the production and utilization of various forms of energy in cells.
The interdisciplinary science that studies evolutionary biology, including the origin and evolution of the major elements required for life, their processing in the interstellar medium and in protostellar systems. This field also includes the study of chemical evolution and the subsequent interactions between evolving biota and planetary evolution as well as the field of biology that deals with the study of extraterrestrial life.
Intracellular signaling protein kinases that play a signaling role in the regulation of cellular energy metabolism. Their activity largely depends upon the concentration of cellular AMP which is increased under conditions of low energy or metabolic stress. AMP-activated protein kinases modify enzymes involved in LIPID METABOLISM, which in turn provide substrates needed to convert AMP into ATP.

Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
