Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The phylogenetic position of the Dura Language of Nepal [PDF]

, 2014
The precise phylogenetic propinquity of Dura within the Tibeto-Burman or Trans-Himalayan language family has hitherto been indeterminate. In the absence of compelling comparative evidence, the language has previously been assigned to a subgroup in its ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

The complete chloroplast genome of Prunus apetala, a native deciduous flowering cherry of Japan

Mitochondrial DNA. Part B. Resources, 2019
The complete chloroplast (cp) genome of Prunus apetala was determined. The length of the cp genome of P. apetala is 157,987 bp. A total of 129 genes are comprised of 84 protein-coding genes, 37 tRNA genes, and 8 rRNA ribosomal genes.

A Transcriptomic-Phylogenomic Analysis of the Evolutionary Relationships of Flatworms. [PDF]

, 2015
The interrelationships of the flatworms (phylum Platyhelminthes) are poorly resolved despite decades of morphological and molecular phylogenetic studies [1, 2].

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Phylogenetic Position of African Punctoid Snails (Stylommatophora, Punctoidea, Trachycystinae)

Taxonomy, 2022
The punctoid land snail family Charopidae, as currently defined, is a paraphyletic assemblage of taxa with Gondwanan distribution. It is represented in Africa largely by the pinwheels (genus Trachycystis and allies) and afrodontas (genus Afrodonta and ...
