Maximum-likelihood tree estimation using codon substitution models with multiple partitions [PDF]
, 2015 Erworben im Rahmen der Schweizer Nationallizenzen (http://www.nationallizenzen.ch)Many protein sequences have distinct domains that evolve with different rates, different selective pressures, or may differ in codon bias.

Taxonomic quasi‐primes: peptides charting lineage‐specific adaptations and disease‐relevant loci
Protein Science, Volume 34, Issue 9, September 2025.Abstract The identification of succinct, universal fingerprints that enable the characterization of individual taxonomies can reveal insights into trait development. Here, we introduce taxonomic quasi‐primes, peptide k‐mer sequences that are exclusively present in a specific taxonomy and absent from all others.

Encystment Induces Down-Regulation of an Acetyltransferase-Like Gene in Acanthamoeba castellanii
Pathogens, 2020 Acanthamoeba castellanii is a ubiquitous free-living amoeba. Pathogenic strains are causative agents of Acanthamoeba keratitis and granulomatous amoebic encephalitis. In response to adverse conditions, A.

Frontiers in Microbiology, 2022 Biological soil crusts occur worldwide as pioneer communities stabilizing the soil surface. In coastal primary sand dunes, vascular plants cannot sustain due to scarce nutrients and the low-water-holding capacity of the sand sediment.

Journal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.ABSTRACT Several distantly related, deep‐branching lineages within the eukaryotic tree of life share what is known as the “typical excavate” morphology. This cell architecture includes a suspension‐feeding ventral groove, supported by complex and specific structures of the cytoskeleton, and a vane‐bearing posterior flagellum.

Ancestrality and Mosaicism of Giant Viruses Supporting the Definition of the Fourth TRUC of Microbes
Frontiers in Microbiology, 2018 Giant viruses of amoebae were discovered in 2003. Since then, their diversity has greatly expanded. They were suggested to form a fourth branch of life, collectively named ‘TRUC’ (for “Things Resisting Uncompleted Classifications”) alongside Bacteria ...

Computational and Structural Biotechnology Journal, 2022 Low complexity regions (LCRs) differ in amino acid composition from the background provided by the corresponding proteomes. The simplest LCRs are homorepeats (or polyX), regions composed of mostly-one amino acid type.

Mass Spectrometry in the Elucidation of the Glycoproteome of Bacterial Pathogens [PDF]
, 2010 Presently some three hundred post-translational modifications are known to occur in bacteria in vivo. Many of these modifications play critical roles in the regulation of proteins and control key biological processes.

Mechanisms driving functional divergence of transcription factor paralogs
New Phytologist, Volume 247, Issue 5, Page 2022-2033, September 2025.Summary Transcription factors (TFs) are core components of the regulatory toolkits that control gene expression. The sophistication of these regulatory toolkits dramatically increased during Eukaryotic evolution, accomplished in part by the duplication of existing TFs and the subsequent repurposing of these new paralogs. This process, termed functional
