The cardiolipin analogues of Archaea

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2009
The present article reviews studies of the structure and functional roles of the cardiolipin analogues of extremely halophilic prokaryotes belonging to the Archaea domain. Analogies and differences between the archaeal bisphosphatidylglycerol and the mitochondrial cardiolipin are presented. Furthermore the structure of archaeal glycophospholipid dimers

Identification of an Activity Selector for the Nitroso‐Forming Activity in Bacterial Type‐III Copper Enzymes

Angewandte Chemie International Edition, Accepted Article.
O‐aminophenol oxidases, a specialized subclass of type‐III copper proteins, play a crucial role in the biosynthesis of bioactive nitrosophenols which display antiretroviral and blood cholesterol lowering activity. Another related subclass of type‐III copper proteins, tyrosinases, closely resemble o‐aminophenol oxidases both structurally and ...

SICLE: A high-throughput tool for extracting evolutionary relationships from phylogenetic trees [PDF]

, 2013
We present the phylogeny analysis software SICLE (Sister Clade Extractor), an easy-to-use, high- throughput tool to describe the nearest neighbors to a node of interest in a phylogenetic tree as well as the support value for the relationship. The application is a command line utility that can be embedded into a phylogenetic analysis pipeline or can be ...

Planktonic microbial communities from microbialite‐bearing lakes sampled along a salinity‐alkalinity gradient

Limnology and Oceanography, Volume 67, Issue 12, Page 2718-2733, December 2022., 2022
Abstract Continental freshwater systems are particularly vulnerable to environmental variation. Climate change‐induced desertification and the anthropogenic exploitation of hydric resources result in the progressive evaporation and salinization of inland water bodies in many areas of the globe.

Diel Patterns in the Composition and Activity of Planktonic Microbes in a Subtropical Bay

Ocean-Land-Atmosphere Research
Planktonic microbes play a crucial role in the matter transformation and energy transfer of marine ecosystems. Marine microbial communities are profoundly influenced by various environmental factors, and their variations are typically investigated in a ...

Data compression and genomes: a two dimensional life domain map [PDF]

arXiv, 2008
We define the complexity of DNA sequences as the information content per nucleotide, calculated by means of some Lempel-Ziv data compression algorithm. It is possible to use the statistics of the complexity values of the functional regions of different complete genomes to distinguish among genomes of different domains of life (Archaea, Bacteria and ...

Microbial methods matter: Identifying discrepancies between microbiome denoising pipelines using a leaf biofilm taphonomic dataset

Applications in Plant Sciences, EarlyView.
Abstract Premise The occurrence of different microorganisms on aquatic macrophyte fossils suggests that biofilm microbes may facilitate leaf preservation. Understanding the impact of microorganisms on leaf preservation requires studies on living plants coupled with microbial amplicon sequencing.

Contrasting bacterial and archaeal distributions reflecting different geochemical processes in a sediment core from the Pearl River Estuary

AMB Express, 2020
Microbial community structure and metabolic activities have profound impacts on biogeochemical processes in marine sediments. Functional bacteria such as nitrate- and sulfate-reducing bacteria respond to redox gradients by coupling specific reactions ...

A Unique B-Family DNA Polymerase Facilitating Error-Prone DNA Damage Tolerance in Crenarchaeota

Frontiers in Microbiology, 2020
Sulfolobus islandicus codes for four DNA polymerases: three are of the B-family (Dpo1, Dpo2, and Dpo3), and one is of the Y-family (Dpo4). Western analysis revealed that among the four polymerases, only Dpo2 exhibited DNA damage-inducible expression.

A limiting rule for the variability of coding sequence length in microbial genomes [PDF]

arXiv, 2008
The mean length and the variability of coding sequences for 48 genomes of bacteria and archaea were analyzed. It was found that the plotted data can be described by an angular area. This suggests the followings: a) The variability of a genome increases as the mean length increases; b) There is an upper and a lower limit for variability for a given mean
