  • Protein Targeting in Parasites with Cryptic Mitochondria
    International Journal for Parasitology 37 (2007) 265–272 www.elsevier.com/locate/ijpara Invited review Protein targeting in parasites with cryptic mitochondria Lena Burri, Patrick J. Keeling * Canadian Institute for Advanced Research, Department of Botany, University of British Columbia, 3529-6270 University Boulevard, Vancouver, BC, Canada V6T 1Z4 Received 4 October 2006; received in revised form 5 December 2006; accepted 11 December 2006 Abstract Many highly specialised parasites have adapted to their environments by simplifying different aspects of their morphology or bio- chemistry. One interesting case is the mitochondrion, which has been subject to strong reductive evolution in parallel in several different parasitic groups. In extreme cases, mitochondria have degenerated so much in physical size and functional complexity that they were not immediately recognised as mitochondria, and are now referred to as ‘cryptic’. Cryptic mitochondrion-derived organelles can be classified as either hydrogenosomes or mitosomes. In nearly all cases they lack a genome and all organellar proteins are nucleus-encoded and expressed in the cytosol. The same is true for the majority of proteins in canonical mitochondria, where the proteins are directed to the organelle by specific targeting sequences (transit peptides) that are recognised by translocases in the mitochondrial membrane. In this review, we compare targeting sequences of different parasitic systems with highly reduced mitochondria and give an overview of how the import machinery has been modified

These organelles, known as hydrogenosomes, mi- tosomes, or mitochondrion-like organelles, are typically reduced, both structurally and biochemically, relative to classical mitochondria. How- ever, despite their diversification and adaptation to different niches, all appear to play a role in Fe-S cluster assembly, as observed for mitochon- dria. Although evidence supports the use of common protein targeting mechanisms in the biogenesis of these diverse organelles, divergent fea- tures are also apparent.

  • Unique Features of Entamoeba Sulfur Metabolism; Compartmentalization, Physiological Roles of Terminal Products, Evolution and Pharmaceutical Exploitation
    International Journal of Molecular Sciences Review Unique Features of Entamoeba Sulfur Metabolism; Compartmentalization, Physiological Roles of Terminal Products, Evolution and Pharmaceutical Exploitation Fumika Mi-ichi * and Hiroki Yoshida Division of Molecular and Cellular Immunoscience, Department of Biomolecular Sciences, Faculty of Medicine, Saga University, 5-1-1 Nabeshima, Saga 849-8501, Japan; [email protected] * Correspondence: [email protected]; Tel.: +81-952-34-2294 Received: 30 August 2019; Accepted: 19 September 2019; Published: 21 September 2019 Abstract: Sulfur metabolism is essential for all living organisms. Recently, unique features of the Entamoeba metabolic pathway for sulfated biomolecules have been described. Entamoeba is a genus in the phylum Amoebozoa and includes the causative agent for amoebiasis, a global public health problem. This review gives an overview of the general features of the synthesis and degradation of sulfated biomolecules, and then highlights the characteristics that are unique to Entamoeba. Future biological and pharmaceutical perspectives are also discussed. Keywords: amoebiasis; mitosome; lipid metabolism; encystation; lateral gene transfer 1. Introduction 1.1. Sulfur Metabolism Sulfur is an essential element for life in all living organisms. Sulfate in the environment is typically activated as a prerequisite step for both sulfation and sulfate assimilation pathways. Sulfate activation is broadly found throughout the Bacteria, Protista, Fungi, Plantae, and Metazoa kingdoms [1,2]; KEGG (see Box1). Box 1. Databases. Sulfur metabolism research has greatly benefited from ever-expanding databases, such as the Kyoto Encyclopedia of Genes and Genomes (KEGG) (https://www.genome.jp/kegg/), The National Center for Biotechnology Information (NCBI) (https://www.ncbi.nlm.nih.gov/), and AmoebaDB (https://amoebadb.org/ amoeba/).

The examination will be conducted in English. Faculty examiner: Professor Scott Dawson (UC Davies, USA). Abstract Einarsson, E. 2015. Comparative Cell Biology in Diplomonads. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1303. 84 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9374-5. The diplomonads are a diverse group of eukaryotic flagellates found in microaerophilic and anaerobic environments. The most studied diplomonad is the intestinal parasite Giardia intestinalis, which infects a variety of mammals and cause diarrheal disease. Less is known about Spironucleus salmonicida, a parasite of salmonid fish, known to cause systemic infections with high mortality. We created a transfection system for S. salmonicida to study cellular functions and virulence in detail (Paper I). The system was applied to explore the mitochondrion-related organelle (MRO) in S. salmonicida. We showed that S. salmonicida possesses a hydrogenosome (Paper II) with a higher metabolic capacity than the corresponding MRO of Giardia, the mitosome. Evolutionary analysis of key hydrogenosomal proteins showed ancient origin, indicating their presence in the ancestral diplomonad and subsequent loss in Giardia. Annexins are of evolutionary interest since these proteins are found across all kingdoms.

BMC Biology (2021) 19:193 https://doi.org/10.1186/s12915-021-01129-7 RESEARCH ARTICLE Open Access Inheritance of the reduced mitochondria of Giardia intestinalis is coupled to the flagellar maturation cycle Pavla Tůmová1*, Luboš Voleman2, Andreas Klingl3, Eva Nohýnková1, Gerhard Wanner4 and Pavel Doležal2* Abstract Background: The presence of mitochondria is a distinguishing feature between prokaryotic and eukaryotic cells. It is currently accepted that the evolutionary origin of mitochondria coincided with the formation of eukaryotes and from that point control of mitochondrial inheritance was required. Yet, the way the mitochondrial presence has been maintained throughout the eukaryotic cell cycle remains a matter of study. Eukaryotes control mitochondrial inheritance mainly due to the presence of the genetic component; still only little is known about the segregation of mitochondria to daughter cells during cell division. Additionally, anaerobic eukaryotic microbes evolved a variety of genomeless mitochondria-related organelles (MROs), which could be theoretically assembled de novo, providing a distinct mechanistic basis for maintenance of stable mitochondrial numbers. Here, we approach this problem by studying the structure and inheritance of the protist Giardia intestinalis MROs known as mitosomes. Results: We combined 2D stimulated emission depletion (STED) microscopy and focused ion beam scanning electron microscopy (FIB/SEM) to show that mitosomes exhibit internal segmentation and conserved asymmetric structure. From a total of about forty mitosomes, a small, privileged population is harnessed to the flagellar apparatus, and their life cycle is coordinated with the maturation cycle of G. intestinalis flagella. The orchestration of mitosomal inheritance with the flagellar maturation cycle is mediated by a microtubular connecting fiber, which physically links the privileged mitosomes to both axonemes of the oldest flagella pair and guarantees faithful segregation of the mitosomes into the daughter cells.

    The Origin and Evolution of Microbial Life: Prokaryotes and Protists Chapter.16 Introduction: How Ancient Bacteria Changed the World • Virtually all metabolic pathways on Earth evolved in prokaryotic cells, before the evolution of eukaryotes • The products generated by prokaryotic metabolism changed the Earth’s atmosphere and rocks • Fossilized stromatolites from 3 billion years ago contain the fossils of photosynthetic cyanobacteria – These bacteria produced O2 and made Earth’s atmosphere aerobic Copyright © 2009 Pearson Education, Inc. PROKARYOTES Prokaryotes are diverse and widespread • Prokaryotes lived alone on Earth for over 1 billion years – They remain the most numerous and widespread organisms on Earth – The total biomass of prokaryotes is ten times that of eukaryotes – Most prokaryotes are 1–5 µm in diameter (vs. 10–100 µm for eukaryotic cells) – More prokaryotes live in your mouth than the total number of humans that have ever lived – There are ten times as many prokaryotes living in and on your body as the number of cells in your body Copyright © 2009 Pearson Education, Inc. Prokaryotes are diverse and widespread • Prokaryotes live in cold, hot, salty, acidic, and alkaline habitats • Although some bacteria are pathogenic (pathogen) and cause disease, most bacteria on our bodies are benign or beneficial ! Several hundred species of bacteria live in and on our bodies, • decomposing dead skin cells, • supplying essential vitamins, and • guarding against pathogenic organisms. • Prokaryotes in soil decompose dead organisms, sustaining chemical cycles Copyright © 2009 Pearson Education, Inc. Bacteria and archaea • The two prokaryotic domains, Bacteria and Archaea, diverged soon after life on Earth arose • Present day Archaea and Eukarya evolved from a common ancestor, complicated by gene transfer between prokaryotic lineages • Some genes of Archaea are similar to bacterial genes, some are similar to eukaryotic genes, and some are unique to Archaea External features ! Prokaryotic cells have three common cell shapes.
