Chiral symmetry breaking yields the I-Au60 perfect golden shell of singular rigidity

Nature Communications, 2018
Chiral-icosahedral symmetry is exceptionally rare in molecular systems. Here, the authors predict the spontaneous formation of a stable chiral-icosahedral gold shell, in which all 60 atoms are symmetrically equivalent.

The structure of a 12-segmented dsRNA reovirus: New insights into capsid stabilization and organization.

PLoS Pathogens, 2023
Infecting a wide range of hosts, members of Reovirales (formerly Reoviridae) consist of a genome with different numbers of segmented double stranded RNAs (dsRNA) encapsulated by a proteinaceous shell and carry out genome replication and transcription ...

Formation of a stable deacagonal quasicrystalline Al-Pd-Mn surface layer [PDF]

, 2001
We report the in situ formation of an ordered equilibrium decagonal Al-Pd-Mn quasicrystal overlayer on the 5-fold symmetric surface of an icosahedral Al-Pd-Mn monograin.

Discrete Groups and Internal Symmetries of Icosahedral Viral Capsids

Computational and Mathematical Biophysics, 2014
A classification of all possible icosahedral viral capsids is proposed. It takes into account the diversity of hexamers’ compositions, leading to definite capsid size.We showhowthe self-organization of observed capsids during their production results ...

Structural morphing in a symmetry-mismatched viral vertex

Nature Communications, 2020
In icosahedral viruses, a symmetry-mismatched portal vertex is assembled by inserting a 12-fold-symmetric portal complex into a 5-fold-symmetric capsid environment.

Capsid structure of a fungal dsRNA megabirnavirus reveals its previously unidentified surface architecture.

PLoS Pathogens, 2023
Rosellinia necatrix megabirnavirus 1-W779 (RnMBV1) is a non-enveloped icosahedral double-stranded (ds)RNA virus that infects the ascomycete fungus Rosellinia necatrix, a causative agent that induces a lethal plant disease white root rot.

Crystal morphology of spherical viruses

Записки Горного института, 2021
The article discusses modern views on the structure of spherical virus capsids, which have the shape of icosahedrons (icosahedral viruses). Each face of icosahedron is composed of a single-layer closest packing of protein globules, which can have ...
