Описание: The new edition focuses on the latest information on mitochondrion-derived organelles, particularly on hydrogenosomes and mitosomes. It has become more and more evident that hydrogenosomes and mitosomes are just two specific members of larger family of organelles derived to various extent from mitochondria due to adaptation to oxygen-poor environment and to the parasitic life style. Since the 1st edition, investigation of free-living protists and commensals has revealed that there is a continuous spectrum of mitochondria-derived organelles from typical aerobic mitochondria, mitochondria with stepwise loss of respiratory chain complexes and with concomitant gain of anaerobic pathways (particularly hydrogenase), via hydrogenosomes and mitosomes to the newly discovered organisms that completely lost mitochondria. Most of the experimental data collected relates to the human pathogens Trichomonas vaginalis harboring hydrogenosomes, and Giardia intestinalis and Entamoeba histolytica with mitosoms. In principle, hydrogenosomes are hydrogen and ATP producing organelles, while the only known function in Giardia mitosomes is synthesis of iron-sulfur clusters, whereas mitosomes of E. histolytica possess the recently discovered sulfur activation pathway. Functions of other unusual mitochondria are mostly predicted based on transcriptomic/genomic analyses as corresponding organisms are not amenable to biochemical studies. Investigations on evolution and function of mitochondria-derived organelles substantially changed conventional views on mitochondrion from textbook models of an oxygen-consuming powerhouse of cells to a large family of organelles, variables in their structure and function in which hydrogenosomes and mitosome represent the most divergent anaerobic members.
Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.

Описание: This volume represents the proceedings of the 24th Mos- bach Colloquium on "Regulation of Transcription and Trans- lation in Eukaryotes" which was held April 26-28, 1973, in Mosbach, Germany, under the auspices of the Gesellschaft fiir Biologische Chemie.
Описание: In recent years several different gene silencing phenomena have been discovered in plants. By providing a comparative update on gene silencing effects in different eukaryotes, this book should stimulate communication among scientists working in diverse areas of eukaryotic gene regulation.

Описание: Not many years ago most discussion of mutation induction by physical and chemical agents concentrated on the initial lesions induced in the DNA with the implicit assumption that once the lesions were made they were converted almost automatically to mutations by relatively simple processes associated with DNA replication.

Описание: ГЇВїВЅ Every time a cell divides, a copy of its genomic DNA has to be faithfully copied to generate new genomic DNA for the daughter cells. The Initiation of DNA Replication in Eukaryotes will focus on how DNA replication is initiated in eukaryotic cells.
