Peptide vocabulary analysis reveals ultra-conservation and homonymity in protein sequences [PDF]

open access: yes, 2007
A new algorithm is presented for vocabulary analysis (word detection) in texts of human origin. It performs at 60%–70% overall accuracy and greater than 80% accuracy for longer words, and approximately 85% sensitivity on Alice in Wonderland, a ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Cretaceous bird with dinosaur skull sheds light on avian cranial evolution

open access: yesNature Communications, 2021
In addition to major innovations in their locomotor system, early birds evolved highly derived skulls. Here, Wang et al. three dimensionally reconstruct the skull of a new enantiornithine bird from the Early Cretaceous that illustrates the early avialan ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

A new species of the mud terrapin Pelusios offers insights into early hominin habitats at the Pliocene Hadar Formation of Ethiopia

open access: yesScientific Reports
A novel extinct species of mud terrapin Pelusios awashi sp. nov. is described from the Hadar Formation in Ethiopia. Referred specimens include articulated and isolated specimens from multiple individuals that represent most elements of the shell and a ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
