    Prebiological Evolution and the Metabolic Origins of Life

    Prebiological Evolution and the Andrew J. Pratt* Metabolic Origins of Life University of Canterbury Keywords Abiogenesis, origin of life, metabolism, hydrothermal, iron Abstract The chemoton model of cells posits three subsystems: metabolism, compartmentalization, and information. A specific model for the prebiological evolution of a reproducing system with rudimentary versions of these three interdependent subsystems is presented. This is based on the initial emergence and reproduction of autocatalytic networks in hydrothermal microcompartments containing iron sulfide. The driving force for life was catalysis of the dissipation of the intrinsic redox gradient of the planet. The codependence of life on iron and phosphate provides chemical constraints on the ordering of prebiological evolution. The initial protometabolism was based on positive feedback loops associated with in situ carbon fixation in which the initial protometabolites modified the catalytic capacity and mobility of metal-based catalysts, especially iron-sulfur centers. A number of selection mechanisms, including catalytic efficiency and specificity, hydrolytic stability, and selective solubilization, are proposed as key determinants for autocatalytic reproduction exploited in protometabolic evolution. This evolutionary process led from autocatalytic networks within preexisting compartments to discrete, reproducing, mobile vesicular protocells with the capacity to use soluble sugar phosphates and hence the opportunity to develop nucleic acids. Fidelity of information transfer in the reproduction of these increasingly complex autocatalytic networks is a key selection pressure in prebiological evolution that eventually leads to the selection of nucleic acids as a digital information subsystem and hence the emergence of fully functional chemotons capable of Darwinian evolution. 1 Introduction: Chemoton Subsystems and Evolutionary Pathways Living cells are autocatalytic entities that harness redox energy via the selective catalysis of biochemical transformations.

    Coenzymes Features Discovery, metabolism and functions of NAD Downloaded from http://portlandpress.com/biochemist/article-pdf/37/1/9/3189/bio037010009.pdf by guest on 01 October 2021 and NADP Magali R. VanLinden, Renate Hvidsten Skoge and Mathias Ziegler (University of Bergen, Norway) Nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) are two major players in metabolism as they participate as electron carriers in a multitude of redox reactions. Moreover, they act in life and death decisions on a cellular level in all known life forms. NAD and NADP both exist in two states; the oxidized forms are characterized by a positive charge on the nicotinamide (Nam) moiety, denoted NAD+ and NADP+ respectively. The reduced forms are denoted NADH and NADPH (Figure 1). The independent discoveries of NAD(P) as vitamins and co-enzymes Vitamin B3 is a collective term for the two NAD(P) precursors nicotinic acid (NA) (also referred to as niacin) and Nam, as well as their corresponding ribosides. Niacin and Nam were found to be essential nutrients after severe outbreaks of pellagra (originally thought to be a new pestilence) in 18th Century Europe. Large outbreaks of pellagra occurred in North America in the early 20th Century. Pellagra (from Italian: pelle = skin; agra = sour) is characterized by dermatitis, diarrhoea, dementia and ultimately death, and was widespread in the hundreds of thousands of poor people living on a diet mostly composed of corn or maize flour. Although successfully consumed by American Indians for centuries, degerminated maize does not contain niacin in a bioavailable form. The crucial difference was that Figure 1.

    5. POTENTIAL for HUMAN EXPOSURE 5.1 OVERVIEW White

    WHITE PHOSPHORUS 157 5. POTENTIAL FOR HUMAN EXPOSURE 5.1 OVERVIEW White phosphorus can enter the environment from its production, use, accidental spills during loading and unloading for shipment, and accidental spills during transport. Hazardous wastes sites containing white phosphorus can also be a source of phosphorus in the environment. White phosphorus has been found in at least 77 of the 1,430 current or former EPA National Priorities List (NPL) hazardous waste sites (HazDat 1996). However, the number of sites evaluated for white phosphorus is not known. The frequency of these sites within the United States can be seen in Figure 5-l. The persistence of elemental phosphorus in the air is very short due to oxidation to phosphorus oxides and ultimately to phosphorus acids. However, the particulate phosphorus aerosol may be coated with a protective oxide layer that may prevent further oxidation and extend the lifetime of particulate phosphorus in air. Both wet and dry deposition remove unreacted elemental phosphorus and the degradation products from the air. Similarly, elemental phosphorus oxidizes and hydrolyzes in water and in soil. A small amount of elemental phosphorus is lost from soil and water by volatilization. Phosphorus is used as a fumigant in the storage of grain. Because of ease of application, pellets of aluminum or magnesium phosphide are commonly used (Garry et al. 1993). Phosphine, a highly toxic gas, is generated from phosphide. The rate of formation of phosphine (permissible exposure limit [PEL], 0.4 mg/m3) is dependent on the ambient temperature and humidity. Its release is rapid, and it is extremely fatal to the unprotected person (Garry et al.

Indeed bacterial paleontology is one the youngest branches of paleontology. It has began in the end of 20th century and has developed rapidly in recent years. The main tasks of bacterial paleontology are detailed investigation of fossil microorganisms, in particular their morphology and sizes, conditions of burial and products of habitation that are reflected in lithological and geochemical features of rocks. Bacterial paleontology deals with fossil materials and is useful in analysis of the genesis of sedimentary rocks, and sedimentary mineral resources including oil and gas.
