Abstract Mammalian cells require activated folates to generate nucleotides for growth and division. The most abundant circulating folate species is 5-methyl tetrahydrofolate (5-methyl- THF), which is used to synthesize methionine from homocysteine via the cobalamin-dependent enzyme methionine synthase (MTR). -

Asparaginase and Glutaminase Activities of Micro-Organisms
Journal of General MicrobiologjI (1973),76,85-99 85 Printed in Great Britain Asparaginase and Glutaminase Activities of Micro-organisms By A. IMADA, S. IGARASI, K. NAKAHAMA AND M. ISONO Microbiological Research Laboratories, Central Research Dillision, Takeda Chemical Industries, JlisB, Osaka, Japan (Received 14 September 1972; revised 28 November 1972) SUMMARY L-Asparaginase and L-glutaminase activities were detected in many micro- organisms and the distribution of these activities was found to be related to the classification of micro-organisms. Among 464 bacteria, the activities occurred in many Gram-negative bacteria and in a few Gram-positive bacteria. Most members of the family Enterobacteri- aceae possessed L-asparaginase. L-Asparaginase and L-glutaminase occurred together in a large proportion of pseudomonads. Among Gram-positive bacteria many strains of Bacillus pumilus showed strong L-asparaginase activity. Amidase activities were also observed in several strains in other families. L-Asparaginase activity was not detected in culture filtrates of 261 strains of species of the genera Streptomyces and Nocardia, but L-asparaginase and L- glutaminase were detected when these organisms were sonicated. The amidase activities in culture filtrates of 4158 fungal strains were tested. All the strains of Fusarium species formed L-asparaginase. Organisms of the genera Hjyomyces and Nectria, which are regarded as the perfect stage of the genus Fusarium, also formed L-asparaginase. Several Penicillium species formed L-asparaginase. Two organisms of the family Moniliaceae formed L-glutaminase together with L-asparaginase, and a few ascomycetous fungi formed L-asparaginase or L-glutaminase. Among I 326 yeasts, L-asparaginase or L-glutaminase occurred frequently in certain serological groups of yeasts : VI (Hansenula) group, Cryptococcus group and Rhodotorula group. -
Lignite Coal Burning Seam in the Remote Altai Mountains Harbors A

Kadnikov1, Andrey V. Mardanov1, Denis A. Ivasenko2, Dmitry V. Antsiferov2, Alexey V. Beletsky1, Olga V. Karnachuk2 & Nikolay V. Ravin1 Thermal ecosystems associated with underground coal combustion sites are rare and less studied than geothermal features. Here we analysed microbial communities of near-surface ground layer and bituminous substance in an open quarry heated by subsurface coal fre by metagenomic DNA sequencing. Taxonomic classifcation revealed dominance of only a few groups of Firmicutes. Near- complete genomes of three most abundant species, ‘Candidatus Carbobacillus altaicus’ AL32, Brockia lithotrophica AL31, and Hydrogenibacillus schlegelii AL33, were assembled. According to the genomic data, Ca. Carbobacillus altaicus AL32 is an aerobic heterotroph, while B. lithotrophica AL31 is a chemolithotrophic anaerobe assimilating CO2 via the Calvin cycle. H. schlegelii AL33 is an aerobe capable of both growth on organic compounds and carrying out CO2 fxation via the Calvin cycle. Phylogenetic analysis of the large subunit of RuBisCO of B. lithotrophica AL31 and H. schlegelii AL33 showed that it belongs to the type 1-E. All three Firmicutes species can gain energy from aerobic or anaerobic oxidation of molecular hydrogen, produced as a result of underground coal combustion along with other coal gases. We propose that thermophilic Firmicutes, whose spores can spread from their original geothermal habitats over long distances, are the frst colonizers of this recently formed thermal ecosystem. Studies of thermophilic microorganisms that survive and develop at temperatures that are extreme for ordi- nary life have broadened our understanding of the diversity of microorganisms and their evolution, the mech- anisms of adaptation to environmental conditions. -

Abstract: Homocysteine (HCY), a physiological amino acid formed when proteins break down, leads to a pathological condition called hyperhomocysteinemia (HHCY), when it is over a definite limit. It is well known that an increase in HCY levels in blood, can contribute to arterial damage and several cardiovascular disease, but the knowledge about the relationship between HCY and brain disorders is very poor. Recent studies demonstrated that an alteration in HCY metabolism or a deficiency in folate or vitamin B12 can cause altered methylation and/or redox potentials, that leads to a modification on calcium influx in cells, or into an accumulation in amyloid and/or tau protein involving a cascade of events that culminate in apoptosis, and, in the worst conditions, neuronal death. The present review will thus summarize how much is known about the possible role of HHCY in neurodegenerative disease. -

Mannion et al. BMC Genomics (2018) 19:830 https://doi.org/10.1186/s12864-018-5171-2 RESEARCHARTICLE Open Access Comparative genomics analysis to differentiate metabolic and virulence gene potential in gastric versus enterohepatic Helicobacter species Anthony Mannion*, Zeli Shen and James G. Fox Abstract Background: The genus Helicobacter are gram-negative, microaerobic, flagellated, mucus-inhabiting bacteria associated with gastrointestinal inflammation and classified as gastric or enterohepatic Helicobacter species (EHS) according to host species and colonization niche. While there are over 30 official species, little is known about the physiology and pathogenic mechanisms of EHS, which account for most in the genus, as well as what genetic factors differentiate gastric versus EHS, given they inhabit different hosts and colonization niches. The objective of this study was to perform a whole-genus comparative analysis of over 100 gastric versus EHS genomes in order to identify genetic determinants that distinguish these Helicobacter species and provide insights about their evolution/ adaptation to different hosts, colonization niches, and mechanisms of virulence. Results: Whole-genome phylogeny organized Helicobacter species according to their presumed gastric or EHS classification. Analysis of orthologs revealed substantial heterogeneity in physiological and virulence-related genes between gastric and EHS genomes. Metabolic reconstruction predicted that unlike gastric species, EHS appear asaccharolytic and dependent on amino/organic acids to fuel metabolism. Additionally, gastric species lack de novo biosynthetic pathways for several amino acids and purines found in EHS and instead rely on environmental uptake/ salvage pathways. Comparison of virulence factor genes between gastric and EHS genomes identified overlapping yet distinct profiles and included canonical cytotoxins, outer membrane proteins, secretion systems, and survival factors. -
