CarD, an essential activator in Mycobacterium tuberculosis, 20 is found in many bacteria, including Thermus species, but absent in Escherichia coli. To 21 delineate the molecular mechanism of CarD, we determined crystal structures of 22 Thermus transcription initiation complexes containing CarD. The structures show CarD 23 interacts with the unique DNA topology presented by the upstream double- 24 stranded/single-stranded DNA junction of the transcription bubble. We confirm that our 25 structures correspond to functional activation complexes, and extend our understanding 26 of the role of a conserved CarD Trp residue that serves as a minor groove wedge, 27 preventing collapse of the transcription bubble to stabilize the transcription initiation 28 complex. Unlike E. coli RNAP, many bacterial RNAPs form unstable promoter 29 complexes, explaining the need for CarD.

Systema Naturae. the Classification of Living Organisms
Systema Naturae. The classification of living organisms. c Alexey B. Shipunov v. 5.601 (June 26, 2007) Preface Most of researches agree that kingdom-level classification of living things needs the special rules and principles. Two approaches are possible: (a) tree- based, Hennigian approach will look for main dichotomies inside so-called “Tree of Life”; and (b) space-based, Linnaean approach will look for the key differences inside “Natural System” multidimensional “cloud”. Despite of clear advantages of tree-like approach (easy to develop rules and algorithms; trees are self-explaining), in many cases the space-based approach is still prefer- able, because it let us to summarize any kinds of taxonomically related da- ta and to compare different classifications quite easily. This approach also lead us to four-kingdom classification, but with different groups: Monera, Protista, Vegetabilia and Animalia, which represent different steps of in- creased complexity of living things, from simple prokaryotic cell to compound Nature Precedings : doi:10.1038/npre.2007.241.2 Posted 16 Aug 2007 eukaryotic cell and further to tissue/organ cell systems.

Biology 1015 General Biology Lab Taxonomy Handout
Biology 1015 General Biology Lab Taxonomy Handout Section 1: Introduction Taxonomy is the branch of science concerned with classification of organisms. This involves defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. Something that you will learn quickly is there is a lot of uncertainty and debate when it comes to taxonomy. It is important to remember that the system of classification is binomial. This means that the species name is made up of two names: one is the genus name and the other the specific epithet. These names are preferably italicized, or underlined. The scientific name for the human species is Homo sapiens. Homo is the genus name and sapiens is the trivial name meaning wise. For green beans or pinto beans, the scientific name is Phaseolus vulgaris where Phaseolus is the genus for beans and vulgaris means common. Sugar maple is Acer saccharum (saccharum means sugar or sweet), and bread or brewer's yeast is Saccharomyces cerevisiae (the fungus myces that uses sugar saccharum for making beer cerevisio). In taxonomy, we frequently use dichotomous keys. A dichotomous key is a tool for identifying organisms based on a series of choices between alternative characters. Taxonomy has been called "the world's oldest profession", and has likely been taking place as long as mankind has been able to communicate (Adam and Eve?). Over the years, taxonomy has changed. For example, Carl Linnaeus the most renowned taxonomist ever, established three kingdoms, namely Regnum Animale, Regnum Vegetabile and Regnum Lapideum (the Animal, Vegetable and Mineral Kingdoms, respectively).

The tree of life is a useful metaphor for organis- mal genealogical history provided we recognize that branches sometimes fuse. Hennigian cladistics emphasizes only lineage splitting, ignoring most other major phylogenetic processes.

The Neomuran Revolution and Phagotrophic Origin of Eukaryotes and Cilia in the Light of Intracellular Coevolution and a Revised Tree of Life

I combine evidence from multigene trees, palaeontology, and cell biology to show that eukaryotes and archaebacteria are sisters, forming the clade neomura that evolved 1.2 Gy ago from a posibacterium, whose DNA segregation and cell division were destabilized by murein wall loss and rescued by the evolving novel neomuran endoskeleton, histones, cytokinesis, and glycoproteins. Phagotrophy then induced coevolving serial major changes making eu- karyote cells, culminating in two dissimilar cilia via a novel gliding–ﬁshing–swimming scenario. I transfer Chloroﬂexi to Posibacteria, root the universal tree between them and Heliobacteria, and argue that Negibacteria are a clade whose OM, evolving in a green posibacterium, was never lost.

Origin of the Cell Nucleus, Mitosis and Sex: Roles of Intracellular Coevolution Thomas Cavalier-Smith*
Cavalier-Smith Biology Direct 2010, 5:7 http://www.biology-direct.com/content/5/1/7 RESEARCH Open Access Origin of the cell nucleus, mitosis and sex: roles of intracellular coevolution Thomas Cavalier-Smith* Abstract Background: The transition from prokaryotes to eukaryotes was the most radical change in cell organisation since life began, with the largest ever burst of gene duplication and novelty. According to the coevolutionary theory of eukaryote origins, the fundamental innovations were the concerted origins of the endomembrane system and cytoskeleton, subsequently recruited to form the cell nucleus and coevolving mitotic apparatus, with numerous genetic eukaryotic novelties inevitable consequences of this compartmentation and novel DNA segregation mechanism. Physical and mutational mechanisms of origin of the nucleus are seldom considered beyond the long- standing assumption that it involved wrapping pre-existing endomembranes around chromatin. Discussions on the origin of sex typically overlook its association with protozoan entry into dormant walled cysts and the likely simultaneous coevolutionary, not sequential, origin of mitosis and meiosis. Results: I elucidate nuclear and mitotic coevolution, explaining the origins of dicer and small centromeric RNAs for positionally controlling centromeric heterochromatin, and how 27 major features of the cell nucleus evolved in four logical stages, making both mechanisms and selective advantages explicit: two initial stages (origin of 30 nm chromatin fibres, enabling DNA compaction; and firmer attachment of endomembranes to heterochromatin) protected DNA and nascent RNA from shearing by novel molecular motors mediating vesicle transport, division, and cytoplasmic motility. Then octagonal nuclear pore complexes (NPCs) arguably evolved from COPII coated vesicle proteins trapped in clumps by Ran GTPase-mediated cisternal fusion that generated the fenestrated nuclear envelope, preventing lethal complete cisternal fusion, and allowing passive protein and RNA exchange.

Protistology New Views on the Megaclassification of Life*
Protistology 7 (4), 218–237 (2012) Protistology New views on the megaclassification of life* Stefan Luketa Department of Biology and Ecology, Faculty of Science, University of Novi Sad, Serbia Summary This paper provides a review of the existing literature about megaclassification of the living beings. Novel classification system is introduced, including 5 dominions and 17 kingdoms. In addition, a new nomenclature of higher taxa has been proposed with a premise that the dominion names end with a suffix “-biota”, subdominions with a suffix “-konta”, kingdoms with a suffix “-ida” and subkingdoms with a suffix “-ides”. Dominion Prionobiota comprises acellular organisms without nucleic acid, acellular organisms with nucleic acid have been classified in dominion Virusobiota, dominion Bacteriobiota consists of typical prokaryotic organisms, and dominion Archaebiota comprises specific organisms of prokaryotic structure, whereas dominion Eukaryobiota entails all living beings with eukaryotic organization. Key words: Bikonta, eukaryotes, nomenclature, priones, prokaryotes, Unikonta, viruses Introduction 1981, 1988, 1998; Parker, 1982; Shipunov, 2009), and certain authors perceive biodiversity through As humankind grew accustomed to a great numerous kingdoms (e.g. Leedale, 1974; Drozdov, variety of the living beings, a need arose to assort 2003). Nevertheless, none of the up-to-date them. Principles of classification largely differ and classification systems assumes an existence of only three main schools of thought can be distinguished. two kingdoms. In addition, a taxonomic category Part of the authors follow Aristotle and acknowledge beyond a level of kingdom – dominion or domain existence of not more than two kingdoms of the – is being used by some researchers (e.g. Moore, living beings (e.g.
