Amoebae, Giant Viruses, and Virophages Make Up a Complex, Multilayered Threesome

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
Viral infection had not been observed for amoebae, until the Acanthamoeba polyphaga mimivirus (APMV) was discovered in 2003. APMV belongs to the nucleocytoplasmatic large DNA virus (NCLDV) family and infects not only A.

The Origin and Evolution of Viruses as Molecular Organisms [PDF]

open access: yes, 2009
Viruses are the most abundant life forms and the repertoire of viral genes is greater than that of cellular genes. It is also evident that viruses have played a major role in driving cellular evolution, and yet, viruses are not part of mainstream biology,

Supervised Classification Methods for Flash X-ray single particle diffraction Imaging

open access: yes, 2018
Current Flash X-ray single-particle diffraction Imaging (FXI) experiments, which operate on modern X-ray Free Electron Lasers (XFELs), can record millions of interpretable diffraction patterns from individual biomolecules per day.

When holography meets coherent diffraction imaging [PDF]

open access: yes, 2012
Modern imaging techniques at the molecular scale rely on utilizing novel coherent light sources like X-ray free electron lasers for the ultimate goal of visualizing such objects as individual biomolecules rather than crystals. Here, unlike in the case of

Unveiling Common Bean (Phaseolus vulgaris L) RNA‐ and DNA‐Based Virome in Western Kenya: Insights From Metatranscriptomic and Metagenomic Signatures

open access: yesAdvances in Virology, Volume 2025, Issue 1, 2025.
Common bean (Phaseolus vulgaris L) is Kenya’s second most important agricultural product after maize, serving as a vital source of protein for many rural families in Western Kenya. However, viral diseases caused by RNA and DNA viruses greatly impair bean productivity, often leading to yield losses of up to 100%, thus contributing to food insecurity ...

Diversity and structural‐functional insights of alpha‐solenoid proteins

open access: yesProtein Science, Volume 33, Issue 11, November 2024.
Abstract Alpha‐solenoids are a significant and diverse subset of structured tandem repeat proteins (STRPs) that are important in various domains of life. This review examines their structural and functional diversity and highlights their role in critical cellular processes such as signaling, apoptosis, and transcriptional regulation.

Essential versus accessory aspects of cell death: recommendations of the NCCD 2015 [PDF]

open access: yes, 2014
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ‘accidental cell death’ (ACD).

Exploring ORFan domains in giant viruses: structure of mimivirus sulfhydryl oxidase R596.

open access: yesPLoS ONE, 2012
The mimivirus genome contains many genes that lack homologs in the sequence database and are thus known as ORFans. In addition, mimivirus genes that encode proteins belonging to known fold families are in some cases fused to domain-sized segments that ...
