PCA‐Based Database Mining Enables the Discovery of Bacterial Carbene Transferases for Stereodivergent Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
Database mining using principal component analysis (PCA)‐based clustering enabled discovery of bacterial enzymes capable of catalyzing stereodivergent cyclopropanation of styrene. Statistical analyses of sequence data further revealed characteristic structural properties of these enzymes, highlighting the potential of the bioinformatics tools for ...

Identification of the Genes Related to the Glycogen Metabolism in Hyperthermophilic Archaeon, Sulfolobus acidocaldarius

Frontiers in Microbiology, 2021
Glycogen is a polysaccharide that comprises α-1,4-linked glucose backbone and α-1,6-linked glucose polymers at the branching points. It is widely found in organisms ranging from bacteria to eukaryotes.

A hot origin of dissimilatory sulfite reduction catalyzed by DsrAB in the Paleoarchean Era

mLife, EarlyView.
Abstract Dissimilatory sulfite reduction (DSR) has been essential to microbial energy metabolism in the biogeochemical sulfur cycle since the Paleoarchean Era. However, due to the lack of an integrated assessment of geological record and genomic data, the evolutionary origin of DSR remains elusive in terms of time, habitat, and genetic basis.

Validation of the prognosis model SIMAGRIO‐W to predict larval activity in top soil layers for Agriotes larvae in eastern Austria Validierung des Prognosemodells SIMAGRIO‐W zur Vorhersage der Aktivität von Agriotes‐Larven in den obersten Bodenschichten in Ostösterreich

Agricultural and Forest Entomology, EarlyView.
Wireworms migrate within the soil column depending on the temperature and moisture content of the soil. SIMAGRIO‐W model accuracy comparison between Germany and Austria. Different temperature preferences highlight the need for species‐specific modelling.

Cellular Viscosity in Prokaryotes and Thermal Stability of Low Molecular Weight Biomolecules [PDF]

, 2016
Prepint, Texto y GráficosSome low molecular weight biomolecules, i.e., NAD(P)H, are unstable at high temperatures. The use of these biomolecules by thermophilic microorganisms has been scarcely analyzed.

Long-Term Cultivation and Metagenomics Reveal Ecophysiology of Previously Uncultivated Thermophiles Involved in Biogeochemical Nitrogen Cycle

Microbes and Environments, 2018
Many thermophiles thriving in a natural high-temperature environment remain uncultivated, and their ecophysiological functions in the biogeochemical cycle remain unclear.

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...
