Intermediate-Salinity Systems at High Altitudes in the Peruvian Andes Unveil a High Diversity and Abundance of Bacteria and Viruses
(MDPI, 2019)
Intermediate-salinity environments are distributed around the world. Here, we present a snapshot characterization of two Peruvian thalassohaline environments at high altitude, Maras and Acos, which provide an excellent ...
Tracing the phylogenetic history of the Crl regulon through the Bacteria and Archaea genomes
(BMC, 2019)
Background: Crl, identified for curli production, is a small transcription factor that stimulates the association of the sigma(S) factor (RpoS) with the RNA polymerase core through direct and specific interactions, increasing ...
Effect of CO2 Concentration on Uptake and Assimilation of Inorganic Carbon in the Extreme Acidophile Acidithiobacillus ferrooxidans
(FRONTIERS MEDIA SA, 2019)
This study was motivated by surprising gaps in the current knowledge of microbial inorganic carbon (Ci) uptake and assimilation at acidic pH values (pH < 3). Particularly striking is the limited understanding of the ...
ATP6V(0)d2 controls Leishmania parasitophorous vacuole biogenesis via cholesterol homeostasis
(PUBLIC LIBRARY SCIENCE, 2019)
V-ATPases are part of the membrane components of pathogen-containing vacuoles, although their function in intracellular infection remains elusive. In addition to organelle acidification, V-ATPases are alternatively implicated ...
Non-lysosomal Activation in Macrophages of Atlantic Salmon (Salmo salar) After Infection With Piscirickettsia salmonis
(FRONTIERS MEDIA SA, 2019)
Piscirickettsia salmonis is a facultative intracellular pathogen and etiological agent of the systemic disease salmonid rickettsial septicemia. It has been suggested that P salmonis is able to survive in host macrophages, ...
Uncovering the Mechanisms of Halotolerance in the Extremely Acidophilic Members of the Acidihalobacter Genus Through Comparative Genome Analysis
(FRONTIERS MEDIA SA, 2019)
There are few naturally occurring environments where both acid and salinity stress exist together, consequently, there has been little evolutionary pressure for microorganisms to develop systems that enable them to deal ...
Identification of functional signatures in the metabolism of the three cellular domains of life
(PUBLIC LIBRARY SCIENCE, 2019)
In order to identify common and specific enzymatic activities associated with the metabolism of the three cellular domains of life, the conservation and variations between the enzyme contents of Bacteria, Archaea, and ...
Signal peptide recognition in Trypanosoma cruzi GP82 adhesin relies on its localization at protein N-terminus
(NATURE PUBLISHING GROUP, 2019)
Trypanosoma cruzi, the causative agent of Chagas disease, has a dense coat of GPI-anchored virulence factors. T. cruzi GPI-anchored adhesin GP82 is encoded by a repertoire of transcripts containing several in-frame initiation ...
Identification and Unusual Properties of the Master Regulator FNR in the Extreme Acidophile Acidithiobacillus ferrooxidans
(FRONTIERS MEDIA SA, 2019)
The ability to conserve energy in the presence or absence of oxygen provides a metabolic versatility that confers an advantage in natural ecosystems. The switch between alternative electron transport systems is controlled ...
Relationship between photo-physical and electrochemical properties of D--A compounds regarding solar cell applications. 1. Substituent type effect in photovoltaic performance
(SPRINGER, 2019)
Studying the electrochemical characteristics is an important step for determining interactions between molecules and the chemical environment. Moreover, the electrochemical evaluation of dyes is highly needed to establish ...
