Computational Study on Potentially Active Antibacterial Compounds in Secondary Metabolites of Extremophilic Microorganisms

ChemistryOpen, EarlyView.
This study employed density functional theory (DFT) and conceptual DFT (CDFT) to calculate the structures and properties of potential antibacterial compounds derived from 16‐membered lactone ring‐containing secondary metabolites of extremophiles, as well as midecamycin.

Exploring perceptions of extreme environments and extremophiles in Chilean schoolchildren: an ethnographic study

Frontiers in Public Health
Chile is unique because of its diverse extreme environment, ranging from arid climates in the north to polar climates in Patagonia. Microorganisms that live in these environments are called extremophiles, and these habitats experience intense ecosystem ...

The conceptual structure of evolutionary biology: A framework from phenotypic plasticity [PDF]

, 2018
In this review, I approach the role of phenotypic plasticity as a key aspect of the conceptual framework of evolutionary biology. The concept of phenotypic plasticity is related to other relevant concepts of contemporary research in ...

Evolution of lysine and arginine biosynthesis revealed by substrate specificity of lysine biosynthetic enzymes in Thermus thermophilus

The FEBS Journal, EarlyView.
Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.

Communities that thrive in extreme conditions captured from a freshwater lake [PDF]

, 2016
Organisms that can grow in extreme conditions would be expected to be confined to extreme environments. However, we were able to capture highly productive communities of algae and bacteria capable of growing in acidic (pH 2), basic (pH 12) and saline (40

Characterisation of a cold‐adapted, thermostable glucokinase from psychrophilic Pseudoalteromonas sp. AS‐131 reveals how the enzyme achieves high thermal stability without loss of cold adaptation

The FEBS Journal, EarlyView.
We investigated glucokinase from the psychrophilic Pseudoalteromonas sp. AS‐131 (PsGK), which was isolated from the Antarctic Ocean. Biochemical studies revealed that PsGK is a cold‐adapted enzyme with high thermal stability, in contrast to general cold‐adapted enzymes, which have low thermal stability.
